Otto was deposed in the 23 October 1862 Revolution. Multiple causes led to his deposition and exile, including the Bavarian-dominated government, heavy taxation, and a failed attempt to annex Crete from the Ottoman Empire. The catalyst for the revolt was Otto's dismissal of Konstantinos Kanaris from the Premiership. A year later, he was replaced by Prince Wilhelm (William) of Denmark, who took the name George I and brought with him the Ionian Islands as a coronation gift from Britain. A new Constitution in 1864 changed Greece's form of government from constitutional monarchy to the more democratic crowned republic. In 1875 the concept of parliamentary majority as a requirement for the formation of a government was introduced by Charilaos Trikoupis, curbing the power of the monarchy to appoint minority governments of its preference.
