Murad rules for several years through the regency of his mother, Kösem, and a series of grand viziers.

Effective rule, however, remains in the hands of the turbulent sipahiyan (quasi-feudal cavalries) and the Janissaries, who more than once force the execution of high officials.

Corruption of government officials and rebellion in the Asiatic provinces, coupled with an empty treasury, perpetuates the discontent against the central government.

Embittered by the excesses of the troops, Murad is determined to restore Ottoman efficiency and central control both in Constantinople and in the provinces.

The sipahiyan invade the palace in 1632 and demand (and get) the heads of the grand vizier and sixteen other high officials.

Soon afterwards, Murad gains full control and acts swiftly and ruthlessly.

He suppresses the mutineers with a bloody ferocity.

He bans the use of tobacco and closes the coffeehouses and the wineshops (no doubt as nests of sedition), executing violators or mere suspects.
