As the result of negotiations for termination of the trusteeship, the Northern Mariana Islands gained U.S. commonwealth status in 1978, and three other self-governing units, under the military protection of the United States, were established: Palau , the Federated States of Micronesia , and the Marshall Islands . The trusteeship was dissolved in 1990, but Palau remained a trust territory until 1994. See also Caroline Islands .
