Ow okay but I want the history of the pre colonial era

The pre-colonial era refers to the period in history before a region was colonized by a foreign power. For example, in the context of Africa, it would be the history of African societies and kingdoms before the arrival of European colonizers in the 15th century and beyond. This era is characterized by diverse political structures, economic systems, and cultural practices that existed independently of European influence. Key aspects often include the development of empires, trade networks, and unique social organizations.
