The politics of Egypt is based on republicanism, with a semi-presidential system of government. Following the Egyptian Revolution of 2011, and the resignation of President Hosni Mubarak, executive power was assumed by the Supreme Council of the Armed Forces, which dissolved the parliament and suspended the constitution. In 2012, Mohamed Morsi was elected as Egypt's fifth president but was deposed by army chief General Abdel Fattah el-Sisi who was subsequently elected as Egypt's sixth president in 2014.
