 There was a proposal to make Esperanto its official language.In the early 1920s, a great opportunity seemed to arise for Esperanto when the Iranian delegation to the League of Nations proposed that it be adopted for use in international relations, following a report by Nitobe Inazō, an official delegate of League of Nations during the 13th World Congress of Esperanto in Prague.Ten delegates accepted the proposal with only one voice against, the French delegate, Gabriel Hanotaux, who employed France's Council veto privilege to squash all League attempts at recognition of Esperanto, starting on the first vote on December 18, 1920 and continuing through the next three years.
