Why did civil wars occur after decolonization?

Civil wars often erupted after decolonization due to a combination of factors, including the arbitrary borders drawn by colonial powers that ignored ethnic, cultural, and linguistic divisions. The sudden withdrawal of colonial authorities left power vacuums, leading to struggles among various factions vying for control. Additionally, economic instability, political corruption, and the lack of established governance structures further fueled conflicts, as different groups sought to assert their dominance and address grievances. These dynamics created a fertile ground for civil strife in many newly independent nations.
