The reformist period peaked with the Constitution, called the "Kanûn-u Esâsî" (meaning "Basic Law" in Ottoman Turkish), written by members of the Young Ottomans, which was promulgated on 23 November 1876. It established the freedom of belief and equality of all citizens before the law. The empire's First Constitutional era, was short-lived. But the idea of Ottomanism proved influential. A group of reformers known as the Young Ottomans, primarily educated in Western universities, believed that a constitutional monarchy would give an answer to the empire's growing social unrest. Through a military coup in 1876, they forced Sultan Abdülaziz (1861–1876) to abdicate in favour of Murad V. However, Murad V was mentally ill and was deposed within a few months. His heir-apparent, Abdülhamid II (1876–1909), was invited to assume power on the condition that he would declare a constitutional monarchy, which he did on 23 November 1876. The parliament survived for only two years before the sultan suspended it. When forced to reconvene it, he abolished the representative body instead. This ended the effectiveness of the "Kanûn-ı Esâsî".
