Roh Tae-woo was born in Daegu, in southeast Korea, on Dec. 4, 1932, the son of a rural government official who died when Mr. Roh was seven. At the Korean Military Academy he met another poor family’s son, Chun Doo-hwan, and the two forged a friendship that would shape their country’s future.
Speaking the same dialect and bonded by their regional prejudices, the two and their allies from Gyeongsang, a southeast province, climbed the army hierarchy, sponsored by the military strongman at the time, Park Chung-hee. They pulled one another up through a secret club they formed, called Hanahoe, which roughly meant “an association for one-for-all, all-for-one.”
When Mr. Park was assassinated by his spy chief in 1979, Mr. Roh, a division commander charged with guarding the border with North Korea, diverted his troops to support Mr. Chun, at the time a major general and head of the Army Intelligence Command, as Mr. Chun seized power in a coup on Dec. 12, 1979.
They also deployed tanks and paratroopers into the southwestern city of Gwangju, where citizens rose up in an armed rebellion in May 1980. The resulting bloodbath, which came to symbolize the brutality of the South’s military at the time, took at least 191 lives, including 26 soldiers and police officers.
