Mortezaqoli Eqbal al-Saltaneh Makui () was the seventh khan of the Maku Khanate from 1895 to 1923. Born in 1863, he was the son and successor of Teymur Pasha Khan.
He initially persisted in the khanate's policies of isolation and growth, but this made every faction distrust him. This included the Russians, who forced him to stay in Tiflis at the start of World War I. Maku eventually found itself in the combat zone. Its station became an active center when Russian troops constructed a light railway from Shah-takhti (on the Aras river) to Bayazad.
Despite continuous orders from the Iranian government to remain neutral and stop aggressors from passing through his territory, Eqbal al-Saltaneh permitted Turkish nationalist forces access to his territory in November 1920 in order to attack Armenian nationalists.
In January 1924, Eqbal al-Saltaneh was imprisoned for treason in Tabriz by the commander-in-chief Reza Khan, who had his possessions seized. Ten camel loads of gold, twenty camel loads of silver, and three locked Russian safes with unidentified contents were among his seized belongings. An officer was installed as the governor of Maku. Eqbal al-Saltaneh was soon moved to a prison in Tehran, where he was killed on 10 May 1924, reportedly under the orders of Reza Khan.
