The Confederate states of America

Explanation:

on February 1861 the seven (7) southern states of Mississippi, Florida, Alabama, Georgia, south Carolina, Texas, Louisiana, seceded from the United states of America to form their own independent republic which they will call the Confederate states of America.

this secession was caused mostly because the Northern states did not support slavery due to the state rights , just like the south and the south decided to secede to form their own republic and this eventually gave birth to the civil war.

the berlin blockade was an international crisis that arose from an attempt by the soviet union, in 1948–49, to force the western allied powers (the united states, the united kingdom, and france) to abandon their post-world war ii jurisdictions in west berlin. in march 1948 the allied powers decided to unite their different occupation zones of germany into a single economic unit. in protest, the soviet representative withdrew from the allied control council. coincident with the introduction of a new deutsche mark in west berlin (as throughout west germany), which the soviets regarded as a violation of agreements with the allies, the soviet occupation forces in eastern germany began a blockade of all rail, road, and water communications between berlin and the west. on june 24 the soviets announced that the four-power administration of berlin had ceased and that the allies no longer had any rights there.
