The siege of Baghdad in 1733 was a relatively short but intense siege of Baghdad in Ottoman Iraq by the Persian army under Nader Shah. The outcome was determined not at Baghdad but ultimately far to the north near Samara where a large relief force commanded by the Topal Pasha inflicted a decisive defeat on Nader's Persian army (the only battlefield defeat of Nader's career). The Persian besiegers were forced away.
