Following the Lancaster House Agreement there was a transition to majority rule in 1980; the United Kingdom ceremonially granted Zimbabwe independence on 18 April that year. In the 2000s Zimbabwe's economy began to deteriorate due to various factors, including mismanagement and corruption, the imposition of sanctions, such as among others the Zimbabwe Democracy and Economic Recovery Act of 2001, following the switch from Willing Buyer, Willing Seller to Fast Track land reform. Economic instability led several members of the military to try to overthrow the government in a coup d'état in 2007. Prior to independence as Zimbabwe, the nation had been known by several names: Rhodesia, Southern Rhodesia, and Zimbabwe-Rhodesia.
