GU. An unincorporated territory of the United States, the largest and most southerly of the Mariana Islands in the western Pacific Ocean. Inhabited since ancient times by the Chamorro people, Guam was visited by Magellan in 1521 and ceded by Spain to the United States in 1898. Agana is the capital.
The Republican victory in that election resulted in seven Southern states declaring their secession from the Union even before Lincoln took office on March 4, 1861. Both the outgoing and incoming U.S. administrations rejected secession, regarding it as rebellion.
For South Carolina, the legacy of the crisis involved both the divisions within the state during the crisis and the apparent isolation of the state as the crisis was resolved. By 1860, when South Carolina became the first state to secede, the state was more internally united than any other southern state.
