Formed in 1978, the Federated States of Micronesia (FSM) is an island nation in the Caroline archipelago of the western Pacific Ocean. Between 1947 and 1986, these islands were administered by the United States as part of the United Nations Trust Territory of the Pacific Islands. The United Nations trusteeship was terminated in 1986, when the FSM and the United States entered into a Compact of Free Association that guaranteed financial assistance to the FSM in exchange for U.S. authority over matters of security and defense through the year 2000. Communities throughout the FSM are culturally and linguistically heterogeneous.
The time between 1467 and 1568 is known as the period of the Warring States because it is the time period when the Daimyos took the power from the Emperor. Rivals often fought over territory.
