A pro-Muscovite party had taken power in Astrakhan shortly after the Russian capture of Kazan.

Ivan dispatches soldiers to Astrakhan, establishing Darwish Khan as a vassal ruler of the Khanate in 1554.

Pro-muscovite nobles and Nogay tribesmen support the Russian occupation forces.

Hürrem's influence over the Sultan had soon become legendary; she has borne Süleyman five children Mihrimah (daughter), Selim, Beyazıt, Cihangir) and, in an astonishing break with tradition, had eventually been freed and become his legal wife, making Suleyman the first Ottoman Emperor to have a wed wife since Orhan Gazi.

This had strengthened her position in the palace and will lead eventually to one of her sons, Selim, inheriting the empire.

Hürrem also may have acted as Süleyman's adviser on matters of state, and seems to have had an influence upon foreign affairs and international politics.

Theodore Beza, in defense of Calvin and the Genevan magistrates, publishes De haereticis a civili magistratu puniendis.

Calvin presents arguments in favor of the execution of Servetus for diverging from orthodox Christian doctrine, in a treatise published in February 1544 entitled Defense of the orthodox faith in the sacred Trinity (Defensio orthodoxae fidei de sacra Trinitate).
