The Democrat Party was a centre-right political party in Turkey, and the country's third legal opposition party, after the Liberal Republican Party established by Ali Fethi Okyar in 1930, and the National Development Party established by Nuri Demirağ in 1945. Founded and led by Celâl Bayar and Adnan Menderes, it was the first of the opposition parties to rise to power, unseating the Republican People's Party during the national elections of 1950 and ending Turkey's one party era. The party ″facilitated the resurgence of Islam, especially at the popular level, in Turkey″.
