Abd al-Malik gave the early Islamic state its own coins and language
For decades after the Arab conquests, the caliphate still paid with Byzantine and Persian-style coins and kept its books in Greek and Persian. Abd al-Malik changed that, minting a single Islamic currency and making Arabic the language of government. He also built the Dome of the Rock, the oldest surviving monument raised by a Muslim ruler.
Abd al-Malik was born in Medina around 644 or 647 into the Umayyad clan, among the richest families of the Quraysh tribe, and belonged to the first generation born into Islam. Traditional sources describe a pious youth who may have learned the Quran by heart. As a boy he witnessed the assassination of the caliph Uthman in Medina, an experience a historian says left him wary of the city's people. Later he commanded a Medinese naval unit against the Byzantines and served under his father, Marwan.
When the deaths of two caliphs in quick succession in 683 and 684 left Damascus leaderless, most provinces swore allegiance to a rival caliph in Mecca, Abd Allah ibn al-Zubayr. Marwan rebuilt Umayyad power in Syria and Egypt, named Abd al-Malik his heir, and died in 685. The new caliph inherited a fractured realm. An early push into Iraq failed in 686, so he patiently secured his base, accepting an unfavourable truce with Byzantium in 689, crushing a coup by a kinsman in Damascus and winning back rebellious tribes of Upper Mesopotamia.
Then he struck. He took Iraq, and his general al-Hajjaj ibn Yusuf besieged Mecca, where Ibn al-Zubayr was killed late in 692, reuniting the caliphate. Fighting with Byzantium resumed, pushing into Anatolia and Armenia and, in 698, recapturing Kairouan, the base for later conquests of North Africa and Spain. In the east al-Hajjaj, as viceroy, suppressed opposition by 702.
The deeper legacy was administrative. Abd al-Malik centralised rule, controlled provinces with loyal Syrian troops, sent tax surpluses to Damascus, and ended pensions for veterans of the early conquests, paying only serving soldiers. Coinage and the Arabic bureaucracy gave the state a distinctly Islamic identity, and the Dome of the Rock carries the earliest inscriptions proclaiming Islam and Muhammad. He died on 9 October 705, and his son al-Walid I built on these foundations.
