The Portuguese Constitution of 1822 (formally the Political Constitution of the Portuguese Monarchy) (Portuguese: Constituição Política da Monarquia Portuguesa) approved on 23 September 1822 was the first Portuguese constitution, marking an attempt to end absolutism and introduce a constitutional monarchy.[1] Although it was actually in force only for two brief periods, 1822–23 and 1836–38, it was fundamental to the history of democracy in Portugal.[2] It was replaced by the Constitutional Charter of 1826.[3]
