In 1894, he took control of the Mosquito Coast by military force; it had long been the subject of dispute, and was home to a native settlement claimed as a protectorate by the British Empire.
Zelaya's aggressive attitude paid off, and the United Kingdom, which probably did not wish to go to war over this distant land, recognized Nicaraguan seizure of the area.
Both the United Kingdom and US wanted the control of this route, which connected the Caribbean Sea to the Pacific Coast across the San Juan River and Lake Nicaragua.
This threatened to blow up into a full scale Central American war which would endanger the United States Panamanian canal and give European nations, such as Germany, an excuse to intervene to protect the collection of their bank's payments in the region or if failing that then demand a land concession.

The US State Department also demanded that all investments in Central America would also need be approved by the U.S. as a means to protect U.S. interests, peace and liberal institutions.
