WORLD HISTORY

Detailed explanation-1: -Korea was ruled as a part of the Empire of Japan from 1910 to 1945. Joseon had come into the Japanese sphere of influence with the Japan–Korea Treaty of 1876; a complex coalition of the Meiji government, military, and business officials began a process of integrating Korea’s politics and economy with Japan.

Detailed explanation-2: -Japan’s first encounter with Western colonialism was with Portugal in the mid-sixteenth century. The Portuguese brought Catholicism and the new technology of gun and gunpowder into Japan. The latter changed the way samurai rulers fought wars, and accelerated the process of national unification.

Detailed explanation-3: -When Japan was defeated in World War II, Soviet forces took control of the North, and American forces took control of the South, with the 38th parallel as the agreed-upon dividing line. South Korea is independent as of August 15, 1945, and North Korea as of September 9, 1945.

Detailed explanation-4: -Unified Silla lasted for 267 years until falling to Goryeo, under the leadership King Gyeongsun, in 935. Joseon, born out of the collapsed Goryeo in 1392, also ruled the entire peninsula, that rule lasting until Japan annexed Korea in 1910.
