Date of birth

There is no certain information in any source on Mieszko I's life before he took over the government of his lands. Only the Lesser Poland Chronicle ranked the date of his birth between the years 920–931 (depending on the version of the manuscript), but modern researchers don't recognize the Chronicle as a reliable source. Several historians on the basis of their investigations determined the date of Mieszko I's birth between 922–945; the activity of the Duke in his final years of life puts the date of his birth closer to the latter year.

Origin and meaning of his name

There are three major theories concerning the origin and meaning of Mieszko I's name. The most popular theory, proposed by Jan Długosz, explains that Mieszko is a diminutive of Mieczysław, a combination of two elements or lexemes: Miecz meaning sword and Sław meaning famous. Today, this theory is rejected by the majority of Polish historians, who consider the name Mieczysław to have been invented by Długosz to explain the origin of the name Mieszko. Today, we know that ancient Slavs never formed their names using either animal names or weapon names. Ancient Slavic names were abstract in nature. The same explanation rules out another theory about the origin of the name Mieszko, which links the name with the Polish word miś/miśko meaning bear, as no animal names were used to form honorable Polish names among Polish nobility.

The second most popular theory about the origin and sense of Mieszko's name can be traced to the very old legend, firstly described by Gallus Anonymus

) as follows:
At that time (after Mieszko recovered his eyesight) Prince Siemomysł urgently asked the elderly people of his country whether his son's blindness conveyed some miraculous meaning. They explained that this blindness meant that Poland was blind back then, but from now was going to be illuminated by Mieszko and elevated over the neighboring nations.


This interpretation was a clear reference to the later baptism of the Duke:
Poland was indeed blind before, knowing nothing about the true God or the principles of the Catholic faith, but thanks to the enlightenment of Mieszko the country also had become enlightened, because when he adopted the faith, the Polish nation was saved from death and destruction.


In addition, it is known that the Slavic word "mzec" can be interpreted as “having his eyes closed” or “be blind”. Yet again, today it is almost certain that this legend was used as a metaphor, in allusion to the old Slavic pagan ceremony known as the "postrzyżyny": During that ceremony hair cutting was performed to every boy at the age of seven. In that symbolic rite a child became a man. That explains that Mieszko wasn't blind in fact. He was blind only metaphorically. Besides his son’s name was also Mieszko and it is hard to believe that he was also blind. In addition, as we know today ancient Slavs used only abstract names among nobility.

The third theory links the name of Mieszko with his other name, Dagome, as it appeared in the document called Dagome iudex

"Dagome iudex" is one of the earliest historical documents relating to Poland. Poland is not mentioned by name, but reference is made to Dagome and Ote and their sons in 991, placing their land under the protection of the Apostolic See...

. We know this document only from a copy prepared by an anonymous monk who was not familiar with Polish language or Polish names. It is possible that while copying the document he made a mistake and wrote down Dagome instead of Dagomer or even Dagomir. The name Dagomir is used to this day and its construction is similar to other Polish names like for example: Władimir/Włodzimierz or Casimir/Kazimierz. The evolution of the “-mir” element to “-mierz” is due to two separate developments: first, the regular change of the vowel "i" to "(i)e" before "r", and second, the modification of the nominative case by the vocative for certain names (hence, Kazimierz replaced Kazimier based on the vocative Kazimierze). It is debatable whether the name Mieszko is a nickname formed from the second part of the name *Dago-mierz, since the merger in pronunciation of "sz" with the devoiced "rz" which would appear in this position is quite recent. The word mir can be translated as peace. However, some historians believe that the word "Dagome" is a melding of two names: the Christian "Dago," for "Dagobert" (Mieszko's hypothetical baptismal name), and the Slavic "Me," for "Mieszko." The Latin word "iudex" ("judge") would be used in the meaning of "prince." Another interpretation is that "Dagome iudex" is a corruption of "Ego Mesco dux" ("I, Prince Mieszko").

Early reign

Mieszko I took over the tribal rule after his father's death ca. 950–960, probably closer to the latter date. Due to the lack of sources it is not possible to determine exactly which lands he inherited. Certainly among them were the areas inhabited by the Polans

Margrave Gero's war; Mieszko's homage to the Emperor

The chronicle of Thietmar poses some problems of interpretation of the information regarding the attack of Margrave Gero on the Slavic tribes, as a result of which he purportedly subordinated to the authority of the Emperor Lusatia and the Selpuli (meaning the Słupian tribes) and also Mieszko with his subjects. According to the majority of modern historians, Thietmar made an error summarizing the chronicle of Widukind, placing the Gero raid there instead of the fighting that Mieszko conducted at that time against Wichmann the Younger. Other sources make no mention of such conquest and of putting the Polans state on the same footing with the Polabian Slavs. On the other hand, the supporters of the Gero's invasion theory believe that the Margrave did actually carry out a successful invasion, as a result of which Mieszko I was forced to pay tribute to the Emperor
Otto I, Holy Roman Emperor
Otto I the Great , son of Henry I the Fowler and Matilda of Ringelheim, was Duke of Saxony, King of Germany, King of Italy, and "the first of the Germans to be called the emperor of Italy" according to Arnulf of Milan...

 and also was compelled to adopt Christianity through the German Church. The thesis that proposes the introduction of Christianity as a result of this war finds no confirmation in German sources.

The homage is then a separate issue, since, according to the chronicle of Thietmar, Mieszko actually paid tribute to the Emperor from the lands usque in Vurta fluvium (up to the Warta River). In all probability Mieszko decided to pay tribute in order to avoid an invasion similar to the one that Lusatia had suffered. This homage would take place in 965, or in 966 at the latest. Very likely the tribute applied only to the Lubusz land, which was in the German sphere of influence. This understanding of the tribute issue explains why already in 967 Mieszko I was described in the Saxon chronicles as the Emperor's friend (or ally, supporter, Latin: amicus imperatoris).

Marriage and conversion to Christianity

Probably in 964 Mieszko began negotiations with the Bohemian ruler Boleslav I the Cruel. As a result, in 965 Mieszko I married his daughter Dobrawa (also named Dobrava, Doubravka or Dąbrówka). The initiative of the alliance is likely to have come from the Polish ruler. It is probable that the marriage was officially arranged in February of 965.

The next step was the baptism of Mieszko. There are different hypotheses concerning this event. Most often it is assumed that it was a political decision, intended to bring Mieszko's state closer to the Czechs and to facilitate his activities in the Polabian Slavs
Polabian Slavs

 area. At the same time, the baptism decreased the likelihood of future attacks by German margraves and deprived them of the opportunity to attempt Christianization of Mieszko's lands by force. An additional reason could be Mieszko's desire to remove from power the influential pagan priest class, who may have been blocking his efforts to establish a more centralized rule.

A different hypothesis is linked with the above-mentioned acceptance of the veracity of Gero's invasion of Poland. According to it, it was the attack of the Margrave that forced the Christianization, which was to be an act of subordination to the Emperor, done without the mediation of the Pope.

Still other motives were responsible according to Gallus Anonymus

, who claimed that it was the Bohemian Princess Dobrawa who convinced her husband to change his religion. Likewise chronicler Thietmar attributes Mieszko's conversion to Dobrawa's influence. There are no reasons to negate Dobrawa's role in Mieszko's acceptance of Christianity; however crediting rulers' wives with positive influence over their husbands' actions was a common convention at that time.
It is generally recognized that the baptism of Mieszko I took place in 966. The place is unknown; it could have had happened in any of the cities of the Empire

. The belief that the baptism was accomplished through the Czechs in order to avoid the dependence on Germany and the German Church is incorrect, because Bohemia would not have its own church organization until 973. At the time of the baptism of Mieszko the existing Bohemian church establishment was a part of the Regensburg diocese. Thus, if the Polish ruler accepted the baptism through Prague's mediation, it had to be sanctioned in Regensburg. However, the religious vocabulary (words like baptism, sermon, prayer, church, apostle, bishop or confirmation) were adopted from the Czech language

. The latter was a ring-fort some 500 meters in circumference, containing the duke's residence, a stone palace, the country's first monumental architecture.

The Christianization had also led to political changes. The emergent power structures were independent of the traditional tribal elders and limited their authority. Clergy who arrived in the country contributed to the development of education and culture, and of the state administration and diplomacy. At the end of Mieszko's reign (ca. 990) Poland began to pay tribute to the pope (Peter's Pence

However, the conversion of the Polish population into Christianity was a long-term process and was not be completed during the reign of Mieszko I. The duke probably had to deal with rebellions led by the old pagan priest caste. In some villages, the old Slavic beliefs and customs were continued until the 16th century.

, which gave Mieszko the control over the mouth of the Odra River. The German margraves had not opposed Mieszko's activities in Pomerania, perhaps even supported them; the death of the rebellious Wichmann, who succumbed to his wounds soon after the battle, may have been in line with their interests. A telling incident took place after the battle, a testimony to Mieszko's high standing among the Empire's dignitaries, just one year after his baptism: Widukind of Corvey reported that the dying Wichmann asked Mieszko to hand over Wichmann's weapons to Emperor Otto I, to whom Wichmann was related. For Mieszko the victory had to be a satisfying experience, especially in light of his past defeats inflicted by Wichmann.

War against Margrave Odo I of Ostmark

In 972 Poland suffered the attack of Odo I, Margrave of the Saxon Ostmark
Odo I, Margrave of the Saxon Ostmark
Odo I was the Margrave of the Saxon Ostmark from 965 until his death....

. According to the chronicles of Thietmar, this attack was an arbitrary action, without the consent of the Emperor:
Meanwhile, the noble Margrave Hodo, having collected his army attacked Mieszko, who has been faithfully paying tribute to the Emperor (for the lands) up the Warta river.

There are different hypotheses concerning the reasons for this invasion. Possibly Margrave Odo wanted to stop the growing power of the Polish state. Very likely Odo wanted to protect the Wolinian state, which he considered his zone of influence, from the Polish take-over. Possibly the Wolinians themselves called the Margrave and asked his help. In any event, Odo's forces moved in and on 24 June 972 twice engaged Mieszko's army at the village of Cidini, commonly identified with Cedynia

 defeated the Germans in the decisive stage, inflicting great losses among their troops. It may be that Mieszko intentionally staged the retreat, which was followed by a surprise attack on the flank of the German pursuing troops. After this battle, Mieszko and Odo were called to the Imperial Diet in Quedlinburg

 in 973 to explain and justify their conduct. The exact judgment of the Emperor is unknown, but it's certain that the sentence wasn't carried out because he died a few weeks after the Diet. It is commonly assumed that the sentence was unfavorable to the Polish ruler. Some sources indicate that Mieszko was not present in Quedlinburg during the gathering; instead, he had to sent his son Bolesław as a hostage.

Mieszko's conflict with Odo I was a surprising event because, according to Thietmar, Mieszko respected the Margrave highly. Thietmar wrote the following:
Mieszko would never wear his outdoor garment in a house where Odo was present, or remain seated after Odo had gotten up.

Shortly afterwards the young emperor waged a retaliatory expedition against Bohemia, forcing in 978 Duke Boleslav into submission.

In 977 Mieszko's wife, Dobrawa, died. At first there were no apparent repercussions, as the Polish ruler had maintained his alliance with Bohemia.

In 979 Otto II supposedly attacked Poland. Mention of this event can be found in the Chronicle of the Bishops of Cambrai

. Chronicler Thietmar described the event as follows:
When Bolesław's mother died his father married, without permission from the Church, a nun from the monastery in Kalbe, daughter of Margrave Dietrich. Oda was her name and her guilt was great. For she scorned her vows to God, and gave preference to the man of war before him (...). But because of the concern for the well-being of the homeland and the necessity to secure its peace, the event caused no break of relations, instead a proper way was found to restore concord. For thanks to Oda the legion of followers of Christ became augmented, many prisoners returned to their country, the shackled had their chains taken off, and the gates of prisons were opened for the trespassers.


Although Thietmar made no mention of warfare that possibly took place on this occasion, the information on the return of the accord, acting for the good of the country and release of prisoners indicate that a conflict actually did occur.

The marriage with Oda considerably affected the position and prestige of Mieszko, who entered the world of Saxon

, but in the same year Henry II gave up his pretension to the German throne.

The role played by Mieszko I in the subsequent struggles is unclear because the contemporary sources are scarce and not in agreement. Probably in 985 the Polish ruler ended his support for the Bavarian duke and moved to the side of the Emperor. It is believed that Mieszko's motivation was the threat posed to his interests by the Polabian Slavs uprising. The upheaval was a problem for both Poland and Germany, but not for Bohemia. In the Chronicle of Hildesheim

One year later, the Polish ruler had a personal meeting with the Emperor, an event mentioned in the Annals of Hersfeld

:
Otto the boy-king ravaged Bohemia, but received Mieszko who arrived with gifts.


According to Thietmar and other contemporary chronicles the gift given by Mieszko to the Emperor was a camel. The meeting consolidated the Polish-German alliance, with Mieszko joining Otto's expedition against a Slavic land, which together they wholly devastated (...) with fire and tremendous depopulation. It is not clear which Slavic territory was invaded. Perhaps another raid against the Polabians took place. But there are indications that it was an expedition against the Czechs, Mieszko's first against his southern neighbors. Possibly on this occasion the Duke of the Polans accomplished the most significant expansion of his state, the take-over of Lesser Poland

The Thietmar's relation however raises doubts as to whether the joined military operation actually happened. The chronicler claims that a settlement was then concluded between the Emperor and the Bohemian ruler Boleslav II the Pious, which is not mentioned in any other source and is contrary to the realities of the political situation at that time.

Another debatable point is Thietmar's claim that Mieszko subordinated himself to the King. Most historians believe that it was only a matter of recognition of Otto's royal authority. Some suggest that a fealty

Lesser Poland is one of the historical regions of Poland, with its capital in the city of Kraków. It forms the southeastern corner of the country, and should not be confused with the modern Lesser Poland Voivodeship, which covers only a small, southern part of Lesser Poland...

 is also not completely resolved. Possibly Mieszko took the region before 990, which is indicated by the vague remark of Thietmar, who wrote of a country taken by Mieszko from Boleslav. In light of this theory, the conquest of Lesser Poland could be a reason for the war, or its first stage. Many historians suggested that the Czech rule over Lesser Poland was only nominal and likely limited to the indirect control of Kraków
Kraków
Kraków also Krakow, or Cracow , is the second largest and one of the oldest cities in Poland. Situated on the Vistula River in the Lesser Poland region, the city dates back to the 7th century. Kraków has traditionally been one of the leading centres of Polish academic, cultural, and artistic life...

 and perhaps a few other important centers. This theory is based on the lack of archaeological discoveries, which would indicate major building investments undertaken by the Bohemian state.

Lesser Poland supposedly after its incorporation had become the partition of the country assigned to Mieszko's oldest son, Bolesław, which is indirectly indicated in the chronicle of Thietmar.

Some historians, on the basis of the chronicle of Cosmas of Prague
Cosmas of Prague
Cosmas of Prague was a Bohemian priest, writer and historian born in a noble family in Bohemia. Between 1075 and 1081, he studied in Liège. After his return to Bohemia, he became a priest and married Božetěcha, with whom he probably had a son. In 1086 Cosmas was appointed prebendary of Prague, a...

, believe that the conquest of the lands around the lower Vistula River took place after Mieszko's death, specifically in 999. There is also a theory according to which during this transition period Lesser Poland was governed by Bolesław Chrobry, whose authority was granted to him by the Bohemian duke.

Dagome iudex

At the end of his life (ca. 991-92), Mieszko I, together with his wife Oda and their sons, issued a document called Dagome iudex

"Dagome iudex" is one of the earliest historical documents relating to Poland. Poland is not mentioned by name, but reference is made to Dagome and Ote and their sons in 991, placing their land under the protection of the Apostolic See...

, where the Polish ruler placed his lands under the protection of the Pope and described their borders. Only a later imprecise summary of the document has been preserved.

There are two main theories concerning reasons behind the issuing of Dagome iudex:
  • According to the first theory the document was an effort to transform the existing missionary bishopric into a regular organization of the Catholic Church, that would cover all of Mieszko's state. This understanding implies that the arrangement led to payment by Poland of Peter's Pence
    Peter's Pence

Though formally discontinued in England at the time of the Reformation, a post-Reformation payment of uncertain characteristics is seen in some...

    .

  • The second theory assumes that the document was created in order to protect the interests of Mieszko's second wife Oda and their sons (who were named in the document) after Mieszko's death. Bolesław, Mieszko's eldest son, whose mother was Dobrawa, was not named in the document. However, one of Mieszko's and Oda's sons, Świętopełk, also was not mentioned.

Late Reign, death and succession

During his last years of life Mieszko remained loyal to the alliance with the Holy Roman Empire. In 991 he arrived at a gathering in Quedlinburg, where he participated in the customary exchange of gifts with Otto III and Empress Theophanu. In the same year he took part in a joint expedition with the young king to Brandenburg

.

Mieszko died on 25 May 992. Sources give no reasons to believe that his death occurred from causes other than natural. According to Thietmar the Polish ruler died in an old age, overcame with fever. Probably he was buried in the Poznań Cathedral. The remains of the first historical ruler of Poland have never been found and the place of his burial is not known with certainty. In 1836-1837 a cenotaph

 was built for Mieszko I and his successor Bolesław I the Brave in the Golden Chapel at the Poznań Cathedral, where the damaged remains found in the 14th century tomb of Bolesław were placed.

According to Thietmar Mieszko I divided his state before his death among a number of princes. They were probably his sons: Bolesław I the Brave, Mieszko and Lambert.

Organization of the Polish state

The basic structure of the early Polish state was Mieszko's military force. The ruler managed to create an army composed of about 3,000 mounted warriors. Perhaps among them were the Varangians

. This increasingly powerful force allowed the Polans to attack weaker neighboring tribes and conquer their lands. A key factor promoting cohesion of the growing state was fear of the invaders impressed by them among local populations. The first Piasts reinforced their rule by burning local strongholds and replacing them with new larger fortresses, located in strategic positions. Archaeological studies show that this practice was abandoned only at the end of Mieszko's reign, when his position was already well-established.

The largest social group in Mieszko's state were free peasant

Accomplishments

  • Unification of Polish lands. Mieszko's state was the first state that could be called Poland. He is often considered the founder, the principal creator and builder of the Polish state.

  • Acceptance of Christianity and therefore inclusion of his country in the mainstream civilization and political structures of Christian Europe.

  • Erection of churches. The Gniezno Cathedral

Marriages and issue

According to Gallus Anonymus, before becoming a Christian Mieszko had seven pagan wives, whom he had to get rid of as he married Dobrawa. Nothing is known for sure of any children from these relationships. Some sources show the possibility that Adelajda or Adleta (b. 950/60 - d. aft. 997), first wife of Duke Mihály of Gran (Esztergom

According to one hypothesis there was another daughter of Mieszko, married to a Pomeranian Slavic Prince; she could be a daughter of Dobrawa or of one of the previous pagan wives. Also, a theory exists (apparently based on Thietmar and supported by Oswald Balzer
