Ethnic cleansing is the colossal and systematic killing or expulsion of a certain ethnic or religious group with the aims of having a homogenous population. In history, this was done by destroying homes and private properties, desecration of monuments and religious buildings, mass killings, forced migrations, and genocide rape. The holocaust is a common example as around two-thirds of Europe’s Jewish population was annihilated with the objective to have a “pure Aryan race”.
