Yoon Suk Yeol rose fast in South Korean politics before an abrupt downfall

South Korea's Constitutional Court has upheld parliament's impeachment of President Yoon Suk Yeol and removed him from office. The ruling marks a stunning fall for a man who went from a novice in politics to president in 2022, only a year after he entered party politics. His deeply baffling decision to declare martial law and send troops to parliament and other sites in Seoul has ended up as a political suicide. The opposition-controlled parliament quickly voted down Yoon's martial law decree before impeaching him. Yoon was separately indicted by prosecutors on rebellion charges in connection with his decree.
