 From 1920 through 1923, seventeen uprisings or attempted coups in Honduras contributed to growing United States concern over political instability in Central America.In August 1922, the presidents of Honduras, Nicaragua, and El Salvador met on the USS Tacoma in the Gulf of Fonseca.Under the watchful eye of the United States ambassadors to their nations, the presidents pledged to prevent their territories from being used to promote revolutions against their neighbors and issued a call for a general meeting of Central American states in Washington at the end of the year.
