Esperanto is the world's most widely spoken constructed international auxiliary language. Created by L. L. Zamenhof in 1887, it is intended to be a universal second language for international communication, or "the international language". Zamenhof first described the language in Dr. Esperanto's International Language, which he published under the pseudonym Doktoro Esperanto. Early adopters of the language liked the name Esperanto and soon used it to describe his language. The word esperanto translates into English as "one who hopes".
Esperantujo or Esperantio is the community of speakers of the Esperanto language and their culture, as well as the places and institutions where the language is used. The term is used "as if it were a country."
L. L. Zamenhof developed Esperanto in the 1870s and '80s. Unua Libro, the first print discussion of the language, appeared in 1887. The number of Esperanto speakers have increased gradually since then, without much support from governments and international organizations. Its use has, in some instances, been outlawed or otherwise suppressed.
Esperanto culture refers to the shared cultural experience of the Esperantujo, or Esperanto-speaking community. Despite being a constructed language, Esperanto has a history dating back to the late 19th century, and shared socio-cultural norms have developed among its speakers. Some of these can be traced back to the initial ideas of the language's creator, Ludwig Zamenhof, including the theory that a global second language would foster international communication. Others have developed over time, as the language has allowed different national and linguistic cultures to blend together. Some Esperanto speakers have also researched the language's ideologies.
Dr. Esperanto's International Language, commonly referred to as Unua Libro, is an 1887 book by Polish ophthalmologist L. L. Zamenhof, in which he first introduced and described the constructed language Esperanto. First published in Russian on July 26 [O.S. July 14] 1887, the publication of Unua Libro marks the formal beginning of the Esperanto movement.

Angoroj (Agonies) is a 1964 film. It is the first feature film to be produced entirely in Esperanto. It was directed and produced by Jacques-Louis Mahé, a friend of Raymond Schwartz who, under the pseudonym 'Lorjak', had previously produced a silent Esperanto publicity film before World War II titled Antaŭen! (Onwards!).
The World Esperanto Congress is an annual Esperanto convention. It has the longest tradition among international Esperanto conventions, with an almost unbroken run for 119 years. The congresses have been held since August 5, 1905, every year, except during World War I, World War II, and the COVID-19 pandemic. Since the 1920s, the Universal Esperanto Association has been organizing these congresses.
Proto-Esperanto is the modern term for any of the stages in the evolution of L. L. Zamenhof's language project, prior to the publication of Unua Libro in 1887.
The International Youth Congress is the largest annual meeting of young Esperantists in the world. The participants come from all over the world for one week, and they usually number around 300, although there has been a congress with more than 1000 attendees before. The congress takes place in a different country every year and is organized by the World Esperanto Youth Organization, the youth wing of the Universal Esperanto Association. Both the IJK and the World Esperanto Congress take place each summer, usually in consecutive weeks but rarely in the same country.
Esperanto II or Esperanto 2 was a reform of Esperanto proposed by René de Saussure in 1937, the last of a long series of such proposals beginning with a 1907 response to Ido with a project called Lingwo Internaciona, later called Antido 1. Esperanto II was one of several languages investigated by the International Auxiliary Language Association, the linguistic research body that eventually standardized and presented Interlingua de IALA.
Detlev Blanke was a German Esperantist. He was an interlinguistics lecturer at the Humboldt University of Berlin. He was one of Germany's most active Esperanto philologists and was from 1991 to 2016 both the chair of the Gesellschaft für Interlinguistik and the editor of its newsletter, Interlinguistische Informationen. He and his wife, Wera Blanke, were especially interested in the evolution of language, particularly in the development of terminology for the constructed language, Esperanto, and questions of sociolinguistics. Blanke made a study of Eugen Wüster's work toward common international terminology and international standardization.

The Akademio Literatura de Esperanto is an independent and neutral institution which aims to encourage the creative and artistic literary production in the Esperanto language. Officially founded on July 24, 2008, it has been inspired by the efforts made by Esperantlingva Verkista Asocio. In 2021 the ALE began organizing the Intercultural Short Story Competition in Esperanto. The academy should not be confused with the Akademio de Esperanto, whose goal is to steward the evolution of the language.

The Esperanto workers movement has the goal of taking practical advantage of the international language Esperanto for advancing the goals of the labour movement, especially the fight against unrestrained capitalism. It is not only a political movement in the strict sense but also a cultural and educational one. Currently the principal Esperanto associations active in the Esperanto workers movement at the global level are the Sennacieca Asocio Tutmonda and the Internacia Komunista Esperantista Kolektivo, and in a wider sense, the Monda Asembleo Socia.
