How did colonialism contribute to the social stratification observed in post-colonial societies?

Colonialism created a system where a few people held most of the power and wealth while many others were left with very little. When colonial powers took over countries, they often favored certain groups, such as local elites or specific ethnic communities, giving them better access to resources and education. This favoritism led to deep social divisions, as those who were supported by the colonizers gained advantages over others. For example, in many African countries, the colonial government empowered certain tribes, which created lasting inequalities even after independence. As a result, these divisions continued to shape societies, leading to ongoing social stratification where some groups remained wealthy and influential while others struggled.
