North Korea is a dictatorship, and South Korea is a democracy. That's one of the most basic pieces of conventional wisdom about modern geopolitics. But it wasn't always so.

President Yoon Suk Yeol, facing corruption investigations and gridlock in the National Assembly, declared martial law, banning all political activities and independent media. Soldiers stormed the Assembly building as protesters attacked them with fire extinguishers.
