In nations that had substantial European populations, for example Rhodesia (now Zimbabwe) and South Africa, systems of second-class citizenship were often set up in order to give Europeans political power far in excess of their numbers. In the Congo Free State, personal property of King Leopold II of Belgium, the native population was submitted to inhumane treatment, and a near slavery status assorted with forced labor. However, the lines were not always drawn strictly across racial lines. In Liberia, citizens who were descendants of American slaves had a political system for over 100 years that gave ex-slaves and natives to the area roughly equal legislative power despite the fact the ex-slaves were outnumbered ten to one in the general population.
Europeans often altered the local balance of power, created ethnic divides where they did not previously exist, and introduced a cultural dichotomy detrimental to the native inhabitants in the areas they controlled. For example, in what are now Rwanda and Burundi, two ethnic groups Hutus and Tutsis had merged into one culture by the time German colonists had taken control of the region in the nineteenth century. No longer divided by ethnicity as intermingling, intermarriage, and merging of cultural practices over the centuries had long since erased visible signs of a culture divide, Belgium instituted a policy of racial categorization upon taking control of the region, as racially based categorization and philosophies were a fixture of the European culture of that time. The term Hutu originally referred to the agricultural-based Bantu-speaking peoples that moved into present day Rwanda and Burundi from the West, and the term Tutsi referred to Northeastern cattle-based peoples that migrated into the region later. The terms described a person's economic class; individuals who owned roughly 10 or more cattle were considered Tutsi, and those with fewer were considered Hutu, regardless of ancestral history. This was not a strict line but a general rule of thumb, and one could move from Hutu to Tutsi and vice versa.
The Belgians introduced a racialized system; European-like features such as fairer skin, ample height, narrow noses were seen as more ideally Hamitic, and belonged to those people closest to Tutsi in ancestry, who were thus given power amongst the colonised peoples. Identity cards were issued based on this philosophy.
