Books like When Baghdad Ruled the Muslim World by Hugh (Hugh N.) Kennedy

The definitive book on the distinctive history and psychology of ISIS, based on Wood's unprecedented access to the Islamic State's own recruiters and supporters, and his extensive time reporting throughout the region. Based on interviews with Islamic State members and supporters, Wood delivers a fast-paced, riveting narrative about what the Islamic State wants and how it plans to get it. The true story of the on-the-ground reality of the wealthiest, most infamous jihadist group in our world today. A deep dive into the heart of the Islamic State's apocalyptic worldview, this is a bracing look at this terrorist cult from the people who belong to it, promote it and recruit for it.

Jeff Sypeck’s *Becoming Charlemagne* retraces how the Frankish king Karl, crowned by Pope Leo III in 800, built a medieval empire through warfare, diplomacy, and alliances with leaders from Byzantium, the Abbasid Caliphate, and Jewish communities.

For much of its extraordinary life, Baghdad, known for centuries as the "City of Peace," enjoyed both cultural and commercial preeminence. For five centuries it was the seat of the Abbasid Empire, a marvel of glittering palaces, exquisite parks, magnificent mosques, and Islamic colleges. It was a city boasting the most accomplished astronomers, mathematicians, doctors, musicians, and poets-- it was here, in the time of the caliphs, that the great Arabic classic One Thousand and One Nights was set. With its teeming markets watered by the Tigris, Baghdad was a thriving trading emporium, attracting merchants from Central Asia to the Atlantic; its economy was the envy of West and East alike. Yet Baghdad's inhabitants have also seen many terrible hardships, from epidemics and famines to invasions and devastating floods. And it has also been one of the most violent cities on earth. When U.S. troops entered in 2003, they became the latest participants in a turbulent history stretching back to the city's founding in 762. Over most of its thirteen-century history, Baghdad has endured the rule of brutal strongmen, from capricious caliphs to Saddam Hussein; and it has suffered violent occupations at the hands of its conquerors, from the Mongol Hulagu, grandson of Genghis Khan, to Tamerlane, known as the "Sword Arm of Israel." Here, in this vivid new history-- the first published in English in nearly a century-- Justin Marozzi brings to life the whole splendorous and tumultuous story of what was once the greatest capital on earth.

Caliphate is a grand and sweeping history of the caliphate since the death of the prophet Mohammed until the last official caliph in the 13th Century, and its modern incarnations under various Islamist groups today. Contrary to popular belief, Islamic law is not a codified set of legislations, and thus there cannot be one definition of the role of the caliph. Rather, this title has been the subject of serious debate and transformation over time. In Caliphate, historian and Middle East expert Hugh Kennedy lifts the veil on the changing and contested position of the caliph and explores the fascinating succession of various leaders of the Islamic world since the death of the Prophet in 632 until the modern day. Kennedy begins in 7th century Medina, the Prophet Muhammad's city in the Hejaz desert, in the hours following the prophet's death. In the end, Kennedy delves into the modern fate of the caliphate, as the British manipulate the 19th Century caliphs to spur dissent against the Ottomans in the Arab provinces, and Islamist leaders call for the creation of a Muslim caliphate. We witness the emergence of another Abu Bakr as "caliph" in 2014, as Kennedy untangles the twisted and distorted Qur'anic history ISIS uses to justify its barbaric acts. An authoritative new account of the dynasties of leaders who shaped the Arab world, The Caliphate reveals the legacy of one of the most potent political ideas in modern history.
