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.
They felt that his goal was to ignore states rights and remove their ability to own slaves. Before it was all over, eleven states seceded from the Union. Four of these (Virginia, Arkansas, North Carolina, and Tennessee) did not secede until after the Battle of Fort Sumter that occurred on April 12, 1861. Four additional states were Border Slave States that did not secede from the Union: Missouri, Kentucky, Maryland and Delaware.
