Mariana Islands
The Marianas remained a Spanish colony under the general government of the Philippines until 1898, when, as a result of its loss in the Spanish–American War, Spain ceded Guam to the United States. Guam has retained a different political character from the Northern Marianas since this time. Following the Philippine–American War, Apolinario Mabini and other Filipino leaders were exiled to Guam in 1901.
