Hundreds of thousands of people have been internally displaced in Zimbabwe as a result of the actions of their own government. Most recently, tens of thousands of people have been displaced by a campaign of state-sponsored violence following the elections on 29 March 2008. In 2005, an urban clear-up operation referred to as Operation Murambatsvina (Operation “Clear the Filth”) was estimated by the United Nations to have made 570,000 people homeless. Hundreds of thousands of farm workers and their families have been displaced as a result of the government’s fast-track land reform and resettlement programme, which started in 2000. Other groups of people have been arbitrarily displaced for different reasons at different times.
