About

Zamenhof published Esperanto in 1887, although his initial ideas date back as far as 1873. He grew up fascinated by the idea of a world without war and believed that this could happen with the help of a new international auxiliary language (IAL). The language was intended as a tool to gather people together through neutral, fair, equitable communication. He successfully formed a community which has survived to this day, despite the World Wars of the 20th century and various attempts to reform the language or create more modern IALs (Esperanto itself had displaced another similarly-motivated language, Volapük). Additionally, Esperanto has developed like other languages: through the interaction and creativity of its users.

In light of his achievements, and his support of intercultural dialogue, UNESCO selected Zamenhof as one of its eminent personalities of 2017, on the 100th anniversary of his death. According to Esperanto communities, as of 2019 there are approximately 2 million people speaking Esperanto, including approximately 1,000 native speakers, although evidence to that has been heavily disputed, and the last major effort to improve the estimate occurred in 2004.
