This chapter focuses on some of the critical developments and transformations that Turkey’s political regime has undergone since the party’s rise to prominence. The chapter draws attention to the fact that, although Turkey has never been a full liberal democracy, it was, nevertheless, an electoral democracy, and this electoral democracy has gradually turned into competitive authoritarianism, particularly since the alliance between the Gülen Community and the JDP broke down around 2012. Meanwhile, apart from eroding the power of the Kemalist elite through an alliance with Gülenists, the JDP elite, and particularly Erdoğan, have devoted much time and energy into incorporating or destroying some of the most prominent political figures in Turkey’s centre-right political market. This process of reforma, which involved the replacement of the former secularist establishment elite in Turkey with a new conservative elite alliance consisting of Gülenists and the populist JDP elite, led to a catastrophic outcome wherein the erstwhile partners decided no longer to tolerate each other. With the 2016 failed coup and the 2017 constitutional amendment, this process of slow and tumultuous reforma turned into a ruptura, which gave rise to a hegemonic party autocracy out of a multi-party system.
