Britain had long exercised influence over the Mosquito Coast through its relationship with the Mosquito Kingdom, creating a disputed area of sovereignty with Nicaragua. Competing claims over the region required a formal diplomatic resolution to clarify territorial authority and the rights of the indigenous Mosquito people.
On 28 January 1860, the United Kingdom and Nicaragua signed the Treaty of Managua, by which Britain recognised Nicaraguan sovereignty over the Kingdom of Mosquitia. However, the treaty reserved a self-governing enclave called the Mosquito Reservation for the indigenous inhabitants, based on historical rights and prior treaty arrangements.
Disputes over the reservation's degree of autonomy were submitted to arbitration by Franz Joseph I of Austria, who ruled in 1881 that Nicaraguan suzerainty was limited by the reservation's right of self-government. The matter was ultimately resolved in 1905 when the Harrison–Altamirano Treaty annulled the Treaty of Managua and granted Nicaragua full sovereignty over the Mosquito Coast.
Political Outcome
Britain recognised Nicaraguan sovereignty over the Kingdom of Mosquitia, while a self-governing Mosquito Reservation was preserved for indigenous inhabitants; later annulled by the 1905 Harrison–Altamirano Treaty.
Britain held de facto influence over the Mosquito Coast through the Kingdom of Mosquitia
