The Mosquito Coast is an area along the eastern coast of present-day Nicaragua and Honduras. It was named after the local Miskito Nation and was long dominated by British interests and known as the Mosquito Kingdom. From 1860 suzerainty of the area was transferred to Nicaragua with the name Mosquito Reserve, and in November 1894 the Mosquito Coast was militarily incorporated into Nicaragua. However, in 1960, the northern part was granted to Honduras by the International Court of Justice.
