The then Portuguese Council of State was declared extinct in October 1910 when the Portuguese monarchy was overthrown. In 1931, however, during the "Ditadura Nacional" (National Dictatorship), a National Political Council was created. Two years later, upon the adoption of Portugal's Constitution of 1933 creating the "Estado Novo" (New State), the National Political Council became the Council of State. The Constitution of 1933 remained in force until 1976.
