The Fina Venko (Esperanto for "Final Victory") refers to the sudden and sharp rise in the prominence of the Esperanto language during the 2060s, with the number of proficient speakers of the language sharply rising from an estimated 10 million in 2050 to approximately 2 billion by 2070, or 1/5th of the human population at the time.
The Act to Establish the Official Languages of the Union, passed by the Council of the Leagues of Commons of Turtle Island on January 17th, 2060, is generally recognized as the beginning of the Fina Venko. This law, intended to break the disproportionate political power of Anglophones in early Locoti, designated Esperanto as Locoti's spoken lingua franca on the basis of its similarities to the three most widely spoken languages in the union at the time: English, Spanish, and French. The law simultaneously designated the then-endangered Hand Talk as Locoti's signed lingua franca, with primacy over Esperanto as part of Locoti's Indigenous language policy. The law further enacted a number of other policies as part of the Crush Anglo Chauvinism campaign of Locoti's first five-year plan.
Following Locoti's embrace of Esperanto, the European Federation designated Esperanto as one of its own federal languages at the conclusion of its own socialist revolution in 2062. The Constitution of the European Federation also designates Interslavic and European American Sign Language (EASL) as federal languages, with Interslavic being favored in the Slavic-speaking states of the federation, and Esperanto being favored in most other states.
Being an official language of two of the four founding member states, Esperanto was also designated an official language of the Coordinating Body (CB) at its foundation in 2063. Esperanto has been included in every edition of the CB's list of Languages for Cultivation as Lingue Franche ever since, and the momentum provided by the Coordinating Body's embrace of Esperanto kept global interest in the language growing for the rest of the 2060s. By the end of the decade, however, Esperanto had only managed to gain a foothold in the rest of Abya Yala, and had otherwise been outcompeted by languages such as Standard Chinese, Swahili, and Modern Standard Arabic as regional lingue franche, with International Sign establishing itself as the global lingua franca.
Nonetheless, although Esperanto's growth as a second language had leveled off by 2070, Esperanto's growth as a first language would continue until 2090. These native Esperantists now comprise the largest share of the Esperanto community, as the ultimate success of Esperanto left non-natives with fewer reasons to participate in the community.
