The Kemalist One Party State established a dictatorship in Turkey beginning in 1925 through laws that authorized a single party and repressed opposition. The Republican People's Party (RPP) established a monopoly on power and Turkey was officially declared a one party state by 1931. Kemalism, centered around principles like republicanism, secularism, and nationalism, became the dominant state ideology. After Ataturk's death in 1938, Ismet Inonü continued his predecessor's policies as national leader through the 1940s, maintaining a authoritarian regime while pursuing secularization and modernization reforms. Turkey maintained a cautious foreign policy during this period, seeking to avoid conflict until declaring war on Germany in 1945 to qualify for the United Nations.
