The present Constitution of Portugal was adopted in 1976 after the Carnation Revolution. It was preceded by a number of constitutions including the first one created in 1822 (following the Liberal Revolution of 1820), 1826 (drawn up by King Dom Pedro IV), 1838 (after the Liberal Wars), 1911 (following the 5 October 1910 revolution), and 1933 (after the 28 May 1926 coup d'état).
