During his brief majority reign, Murad IV (16121640) reasserted central authority and recaptured Iraq (1639) from the Safavids. The resulting Treaty of Zuhab of that same year decisively parted the Caucasus and adjacent regions between the two neighbouring empires as it had already been defined in the 1555 Peace of Amasya. The Sultanate of women (16481656) was a period in which the mothers of young sultans exercised power on behalf of their sons. The most prominent women of this period were Kosem Sultan and her daughter-in-law Turhan Hatice, whose political rivalry culminated in Kosem's murder in 1651. During the Koprulu Era (16561703), effective control of the Empire was exercised by a sequence of Grand Viziers from the Koprulu family. The Koprulu Vizierate saw renewed military success with authority restored in Transylvania, the conquest of Crete completed in 1669, and expansion into Polish southern Ukraine, with the strongholds of Khotyn and Kamianets-Podilskyi and the territory of Podolia ceding to Ottoman control in 1676.

When was Kosem murdered?
Answer: 1651

Artists such as Gary Numan, the Human League, Soft Cell, John Foxx and Visage helped pioneer a new synthpop style that drew more heavily from electronic and synthesizer music and benefited from the rise of MTV. Post-punk artists such as Scritti Politti's Green Gartside and Josef K's Paul Haig, previously engaged in avant-garde practices, turned away from these approaches and pursued mainstream styles and commercial success. These new developments, in which post-punk artists attempted to bring subversive ideas into the pop mainstream, began to be categorized under the marketing term new pop.

What else began to emerge as post-punk groups moved to a more commercial focus?
Answer: pop

Meleager and the infantry supported the candidacy of Alexander's half-brother, Philip Arrhidaeus, while Perdiccas, the leading cavalry commander, supported waiting until the birth of Alexander's unborn child by Roxana. After the infantry stormed the palace of Babylon, a compromise was arranged Arrhidaeus (as Philip III) should become king, and should rule jointly with Roxana's child, assuming that it was a boy (as it was, becoming Alexander IV). Perdiccas himself would become regent (epimeletes) of the empire, and Meleager his lieutenant. Soon, however, Perdiccas had Meleager and the other infantry leaders murdered, and assumed full control. The generals who had supported Perdiccas were rewarded in the partition of Babylon by becoming satraps of the various parts of the empire, but Perdiccas' position was shaky, because, as Arrian writes, "everyone was suspicious of him, and he of them".

Who was Philip Arrhidaues' half brother?
Answer:
Alexander
