Colonial rule

Introduced diseases

According to a 2021 study by Jörg Baten and Laura Maravall on the anthropometric influence of colonialism on Africans, the average height of Africans decreased by 1.1 centimetres upon colonization and later recovered and increased overall during colonial rule. The authors attributed the decrease to diseases, such as malaria and sleeping sickness, forced labor during the early decades of colonial rule, conflicts, land grabbing, and widespread cattle deaths from the rinderpest viral disease.
