Treaty of Managua

The Treaty of Managua was an 1860 agreement between Great Britain and Nicaragua, in which Britain recognised Nicaraguan sovereignty over its present national territory, but reserved, on the basis of historical rights, a self-governing enclave for the Miskito, an indigenous group in the area, citing earlier treaty arrangements and historical circumstances.
The question was referred for arbitration to the Emperor of Austria, Franz Joseph I, whose award, published on 2 July 1881, upheld the contention of the Indians, and affirmed that the suzerainty of Nicaragua was limited by the Miskitos' right of self-government.
On 19 April 1905, the two countries signed the Harrison Altamirano Treaty which annulled the Treaty of Managua. In this treaty, the United Kingdom recognised absolute Nicaraguan sovereignty over the Mosquito Coast.
