The Seoul Capital Area is home to almost half of the 50 million strong population of South Korea. Seoul was transformed by the 'Miracle on the Han River'. This is the name give to the period following the Korean War (1950-53) which witnessed rapid reconstruction and development much like West Germany following World War II (Miracle on the Rhine). From 1910-45, Korea had been a colony of the Japanese Empire. After the World War, Korea was split in two as part of the Cold War with both governments claiming to be the legitimate government. The Korean War pitted the China backed North against the United States backed South. Seoul changed hands a number of times. An armistice was signed in 1953, but the two Koreas are still technically at war. Despite this difficult history, the city has thrived, and is ranked first by PWC's 'cities of opportunity' report, as the world's most wired. 95% of South Korean households have broadband connection.
