Saud bin Faisal Al Saud (Arabic: سعود بن فيصل بن تركي آل سعود), also known as Imam Saud (Arabic: إمام الدولة السعودية الثانية), (1833—1875) was the ruler of the Second Saudi State in 1871 and 1873–75. He joined alliances with foreign tribes and revolted against his half-brother Abdullah. His rule was short-lived and Abdullah overthrew him. Saud gained power again in 1873 but died two years later. His reign was notable for the infighting in the House of Saud which he initiated.
