Lee Jae-myung has been sworn in as South Korea’s new president after winning a snap election held in the wake of the impeachment of his conservative predecessor. His inauguration marks the start of a political reset for one of Asia’s key democracies after months of intense instability.

The election was triggered by the removal of the previous president, a rare and consequential event that deepened public debate over leadership, accountability, and the direction of the country. Lee, a liberal politician, enters office with voters expecting him to restore confidence in government institutions and steer the country through a period of political division.

His presidency begins at a sensitive moment for South Korea, which faces domestic pressure over governance and economic concerns while also navigating a challenging regional security environment. The transition underscores how quickly the country’s political landscape has shifted after the upheaval that led to the snap vote.

Lee’s administration will now be judged on whether it can stabilize the government, address public frustration, and build support across a polarized electorate. The outcome of that effort will shape South Korea’s domestic politics well beyond this initial transition.
