Political dissension reached its peak in May 631, when "Ichan" Chilsuk (이찬 칠숙) and "Achan" Seokpum (아찬 석품) plotted an uprising based on their opposition to having Princess Deokman as their next ruler. The revolt was discovered in advance and was stopped by Alcheon and Bidam; Chilsuk was beheaded in public and his relatives executed. Although Seokpum was able to escape, he later returned and was eventually captured and killed. With the rebellion put down, power was left mainly in the hands of the King's supporters (the most important of them was Kim Yushin, Commander in Chief of the Royal Army from 629), and it was in this political atmosphere that Princess Deokman was able to become Queen.
