What was the yalta conference and why was it important

The Yalta Conference, also known as the Crimea Conference and code-named the Argonaut Conference, held from 4 to 11 February 1945, was the World War II meeting of the heads of government of the United States, the United Kingdom and the Soviet Union for the purpose of discussing Germany and Europe's postwar reorganization. The three states were represented by President Franklin D. Roosevelt, Prime Minister Winston Churchill and Premier Joseph Stalin, respectively. The conference convened near Yalta in Crimea, Soviet Union, within the Livadia, Yusupov, and Vorontsov Palaces.

President Lincoln feared it was the end of democracy because the main reason for their secession was due to him winning the presidential election as a Republican.

This angered the people of South Carolina and they declared that they were leaving the Union. Six more states followed a month later and, by June, a total of 11 southern states were no longer part of the country.
