Lee Kun-hee, the long-time chairman of Samsung Group who transformed the conglomerate into one of the world’s largest business empires, died today at the age of 78, according to reports from South Korean leading news agency Yonhap. The story of Samsung is deeply intertwined with the history of its home country, which is sometimes dubbed “The Republic of Samsung.” Lee, the son of Samsung founder Lee Byung-chul, came to power in the late 1980s just as South Korea transitioned from dictatorship to democracy with the political handover from military strongman Chun Doo-hwan to Roh Tae-woo.
