The document summarizes the origins and impacts of the partition of Korea after World War 2. It discusses how the US drew the 38th parallel as a temporary dividing line which later became permanent. This led to the establishment of South Korea, backed by the US, and North Korea, backed by the Soviet Union. The division deepened during the Cold War and ideologically as South Korea became democratic and capitalist while North Korea became communist under Kim Il Sung. The partition had long lasting social and political impacts on the Korean people and nation.
