Abd al-Malik (685-705 AD) was the most eminent Caliph of the Umayyads, the second Islamic dynasty. He consolidated and expanded Islamic rule, made Arabic the state language in his realm, and established the first Islamic coinage system. This reform was realized in 79 AH, the year of 698 AD thus, with the introduction of golden dinars, silver dirhams and copper falus. The new coins did not bear images any more, but featured religious formulas.
