At this time, Joseon Dynasty politics was primarily marked by power struggle between two aristocratic yangban factions - the established "Hungu" power elites who were generally conservative and the upstart Sarim scholars called seonbis, who belonged to neo-Confucian school of Kim Jong-jik and other thinkers. Sarim faction had entered the court politics during the reign of King Seongjong but suffered two bloody purges under his successor Yeonsangun. When Yeonsangun was eventually deposed in 1506, Jungjong was placed on the throne as the eleventh king of Joseon by the Hungu leaders who led the coup. For first ten years of his reign, Jungjong could not truly rule the country with regal authority (he was forced to depose his faithful queen because her father was killed by the coup leaders, and they feared that the queen might take revenge.) However, three main coup leaders died of natural causes by then, and Jungjong began to welcome Sarim scholars to his court to check Hungu faction's power. The Sarim faction considered Hungu faction as a whole as greedy and corrupt men unworthy of respect and sought to establish ideal neo-Confucian society. (Indeed, many of coup leaders had enjoyed Yeonsangun's favor during most of his reign, and their chief Park Won-jong led the coup mainly for personal revenge for his sister was raped by Yeonsangun.)
