Background: After the government of the first South Korean President Rhee Seung-man toppled in the April Revolution of 1960, Park Chung-hee staged a military coup, after which he ruled South Korea for 18 years. The Yushin Constitution of 1972 guaranteed Park’s perpetual dictatorship by the election of the president [away] from the voters to an electoral college, alloting one third of the National Assembly seats to appointment by the president, giving the president authority to issue emergency decrees and suspend the Constitution, and giving the president authority to appoint all judges and dismiss the National Assembly. By the late 1970s, demonstrations against the Yushin system erupted throughout the country. When Park Chung-hee was assassinated on October 26, 1979, it seemed as if the spring would com early to Seoul.
