Ekmeleddin Denktaṡ Atatürcak (15 June 4007–8 November 4095) was a Kalopian politician and statesman. He served as Premier of Kalopia in 4063, and then as President from 4063 to 4080, presiding over a period of rapid modernization and secularization as de facto dictator. During large parts of his presidency, the opposition was outlawed, and his government exercized strict control of the media, schools and businesses in the country.
Despite his authoritarian leanings, Atatürcak was widely popular with Kalopia's population, especially in its ethnic Turjak minority; his support among the ethnic Kalopians was significantly weaker. Atatürcak, himself an ethnic Turjak, was criticized for alleged discrimination against, and neglect of, the ethnic Kalopian population.
During his 17-year rule, at the helm of the then-Motherland Party, he introduced a series of reforms to Kalopian society, implementing gender equality and secularism on the national level, despite protests from a suppressed, Ahmadist-rooted opposition. His government also pursued language reform, making considerable changes to the Tukaric language.
Atatürcak died in 4295, during the presidency of his successor as Motherland Party leader, Binali Kırmızıgül. 13 months later, Kırmızıgül shut down the party, and established what would become the Socialist Düstur Party in its place. These and other successor parties have been categorized as denktashist, or following an ideology built on the policies Ekmeleddin Denktaṡ Atatürcak carried out in his lifetime.
