Answer:
The correct answer is Secession
Explanation:
Secession refers to the spontaneous abandonment of one or more states from the Union that constitutes the United States of America. In other words, it is leaving a territory to form a separate territory or new state. In the history of the USA, a secession was advanced in 1860 when some southern states each declared secession from the United States, to form the Confederate States of America. However, this movement failed in 1985 because the Confederate forces were defeat by the Union armies in the American Civil War.
