Who became more and more hostile to the idea of slavery on moral grounds

Slavery is the major issue among the North and the South. At the beginning of the 1850s, the Northerners became more and more hostile to the idea of slavery on moral grounds, whereas slavery is sustained to be a recognized truth of life in the South. This cause led to the start of 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.
