Who dated Mehmed III?

Mehmed III (Ottoman Turkish: محمد ثالث, Meḥmed-i sālis; Turkish: III. Mehmed; 26 May 1566 – 22 December 1603) was the sultan of the Ottoman Empire from 1595 until his death in 1603. Mehmed was known for ordering the execution of his brothers and leading the army in the Long Turkish War, during which the Ottoman army was victorious at the Battle of Keresztes. This victory was however undermined by some military losses such as in Győr and Nikopol. He also ordered the successful quelling of the Jelali rebellions. The sultan also communicated with the court of Elizabeth I on the grounds of stronger commercial relations and in the hopes of England to ally with the Ottomans against the Spanish.

Handan Sultan (Ottoman Turkish: خندان سلطان; c. 1570 – 9 November 1605) was a consort of Ottoman Sultan Mehmed III, and mother and Valide Sultan to their son Sultan Ahmed I. She was de facto regent for her son, a politically influential woman during her tenure from 1603 to 1605 for her son. Handan Sultan was one of the prominent figures during the era known as the Sultanate of Women and lived during the reign of three ottoman Sultans: Murad III, Mehmed III and Ahmed I.

After entering the Ottoman Imperial Harem—probably in 1583—she became one of the two known consorts of then-Prince Mehmed; she succeeded in making her third son, Ahmed, the heir to the throne, after her husband's accession as Sultan Mehmed III in 1595, through alliances with her mother-in-law Safiye Sultan. Initially overshadowed by her mother-in-law and kept away from politics, she acquired power and influence after her consort's death in 1603, becoming the Valide Sultan under her son, now Sultan Ahmed I.

As mother of the new Sultan, she firstly banished Safiye and all her allies, then acted as the first recognized de facto Regent of the Ottoman Empire, taking active positions in politics, affairs of state, power and influence. One of her merits would have been the abolition of the law of fratricide during her son's reign, and having created an effective and capable government apparatus. She died in 1605, having served as the Valide Sultan only for two years: her cause of death is still debated.

Halime Sultan (Ottoman Turkish: حلیمه سلطان; c. 1570 – after 1623) was a consort of Sultan Mehmed III, and the mother of Sultan Mustafa I. The first woman to be Valide Sultan twice and the only to be Valide twice of a same son. She was a de facto co ruler of Ottoman Empire as Valide Sultan from 1617 to 1618 and again from 1622 to 1623, as her son was mentally unstable. Halime was also one of the prominent figures during the era known as the Sultanate of Women.

Halime lived in the Ottoman Empire as a courtier during the reign of seven Sultans: Murad III, Mehmed III, Ahmed I, Mustafa I, Osman II, Murad IV.
