Development of the language before publication

Zamenhof would later say that he had dreamed of a world language since he was a child. At first he considered a revival of Latin

, but after learning it in school he decided it was too complicated to be a common means of international communication. When he learned English, he realised that verb conjugations

 were unnecessary, and that grammatical systems could be much simpler than he had expected. He still had the problem of memorising a large vocabulary, until he noticed two Russian signs labelled Швейцарская (švejtsarskaja, a porter's lodge – from швейцар švejtsar, a porter) and Кондитерская (konditerskaja, a confectioner's shop – from кондитер konditer, a confectioner). He then realised that a judicious use of affix

In 1895 he wrote, "I worked for six years perfecting and testing the language, even though it had seemed to me in 1878 that it was already completely ready." When he was ready to publish, the Czarist censors would not allow it. Stymied, he spent his time in translating works such as the Bible and Shakespeare

Esperanto history from publication until the first world congress

At first the movement grew most in the Russian empire and eastern Europe, but soon spread to western Europe and beyond: to Argentina in 1889; to Canada in 1901; to Algeria, Chile, Japan, Mexico, and Peru in 1903; to Tunisia in 1904; and to Australia, the United States, Guinea, Indochina

, and Uruguay in 1905.

In its first years Esperanto was used mainly in publications by Zamenhof and early adopters like Anton Grabowski, in extensive correspondence (mostly now lost), in the magazine La Esperantisto, published from 1889 to 1895 and only occasionally in personal encounters.

In 1894 under pressure from Wilhelm Trompeter, the publisher of the magazine La Esperantisto, and some other leading users, Zamenhof reluctantly put forward a radical reform to be voted on by readers. He proposed the reduction of the alphabet to 22 letters (by eliminating the accented letters and most of their sounds), the change of the plural to -i, the use of a positional accusative instead of the ending -n, the removal of the distinction between adjectives and adverbs, the reduction of the number of participles from six to two, and the replacement of the table of correlatives with more Latinate words or phrases. These reforms were overwhelmingly rejected, but some were picked up in subsequent reforms
Esperantido

A small international conference was held in 1904, leading to the first world congress in August 1905 in Boulogne-sur-Mer

Esperanto history since the first congress

World congresses have been held every year since 1905, except during the two World Wars.

The autonomous territory of Neutral Moresnet, between Belgium and Germany, had a sizable proportion of Esperanto-speakers among its small and multiethnic population. There was a proposal to make Esperanto its official language.

In the early 1920s, there was a proposal for the League of Nations

. Hanotaux did not like how the French language was losing its position as the international language and saw Esperanto as a threat.

The creation of a Jew-free National German Esperanto League was not enough to placate the Nazis.
The teaching of Esperanto was not allowed in German prisoner-of-war camps during World War II. Esperantists sometimes were able to get around the ban by convincing guards that they were teaching Italian, the language of Germany's closest ally.

While Esperanto itself was not enough cause for execution, its use was extended among Jews or trade unionists and encouraged contacts with foreigners.

However, the language experienced something of a renaissance in the 1970s and spread to new parts of the world, such as its veritable explosion in popularity in Iran in 1975. By 1991 there were enough African Esperantists to warrant a pan-African congress. The language continues to spread, although it is not officially recognised by any country, and is part of the state educational curriculum of only a few.

Evolution of the language

The Declaration of Boulogne
Declaration of Boulogne
The Declaration of Boulogne was a document written by L. L. Zamenhof and endorsed by the attendees of the first world congress of Esperanto in Boulogne-sur-Mer, France in 1905...

  of 1905 limited changes to Esperanto. That declaration stated, among other things, that the basis of the language should remain the Fundamento de Esperanto ("Foundation of Esperanto", a group of early works by Zamenhof), which is to be binding forever: nobody has the right to make changes to it. The declaration also permits new concepts to be expressed as the speaker sees fit, but it recommends doing so in accordance with the original style.

Many Esperantists believe this declaration stabilising the language is a major reason why the Esperanto speaker community grew beyond the levels attained by other constructed languages and has developed a flourishing culture. Other constructed languages have been hindered from developing a stable speaking community by continual tinkering. Also, many developers of constructed languages have been possessive of their brain-children and have worked to prevent others from contributing to the language. One such ultimately disastrous case was Schleyer

. In contrast, Zamenhof declared that "Esperanto belongs to the Esperantists", and moved to the background once the language was published, allowing others to share in the early development of the language.

The grammatical description in the earliest books was somewhat vague, so a consensus on usage (influenced by Zamenhof's answers to some questions) developed over time within boundaries set by the initial outline (Auld 1988). Even before the Declaration of Boulogne, the language was remarkably stable; only one set of lexical changes were made in the first year after publication, namely changing "when", "then", "never", "sometimes", "always" from kian, tian, nenian, ian, ĉian to kiam, tiam, neniam etc., to avoid confusion with the accusative forms of kia "what sort of", tia "that sort of", etc. Thus Esperanto achieved a stability of structure and grammar similar to that which natural languages enjoy by virtue of their native speakers and established bodies of literature. One could learn Esperanto without having it move from underfoot. Changes could and did occur in the language, but only by acquiring widespread popular support; there was no central authority making arbitrary changes, as happened with Volapük

 and some other languages.

Modern Esperanto usage may in fact depart from that originally described in the Fundamento, though the differences are largely semantic (involving changed meaning of words) rather than grammatical or phonological. The translation given for "I like this one", in the sample phrases in the main Esperanto

 article, offers a significant example. According to the Fundamento, Mi ŝatas ĉi tiun would in fact have meant "I esteem this one". The traditional usage is Tiu ĉi plaĉas al mi (literally, "this one is pleasing to me"), which reflects the phrasing of most European languages (French celui-ci me plaît, Spanish éste me gusta, Russian это мне нравится [eto mnye nravitsya], German Das gefällt mir, Italian mi piace). However, the original Ĉi tiu plaĉas al mi continues to be commonly used.

s through natural language use. This may be because it is the language of daily communication for only a small minority of its speakers. However at least three other factors work against dialects, namely the centripetal force of the Fundamento, the unifying influence of the Plena Vortaro and its successors, which exemplified usage from the works of Zamenhof and leading writers, and the transnational ambitions of the speech community itself. Slang and jargon

, as well as removal of adjectival agreement and the accusative case except when necessary. At first a number of leading Esperantists put their support behind the Ido project, but the movement stagnated and declined, first with the accidental death of one of its main proponents and later as people proposed further changes, and the number of current speakers is estimated at between 250 and 5000. However, Ido has proven to be a rich source of Esperanto vocabulary.

Some more focused reform projects, affecting only a particular feature of the language, have gained a few adherents. One of these is "riism
