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.
South Carolina acted first, calling for a convention to secede from the Union. State by state, conventions were held, and the Confederacy was formed. Within three months of Lincoln's election, seven states had seceded from the Union. Just as Springfield, Illinois celebrated the election of its favorite son to the Presidency on November 7, so did Charleston, South Carolina, which did not cast a single vote for him.
