Ali Rıza Pasha (sometimes spelled Ali Ridha Pasha) leads the Ottoman army in 1831 against the Mamluk governor in Baghdad after Dawud Pasha refuses to give up his office.

Ali Rıza Pasha captures the city and Dawud, ending the Mamluk rule in Baghdad.

Baghdad falls in September 1831 after a ten-week-long blockade of the city that causes mass famine.
