The history of Uganda comprises the history of the people who inhabited the territory of present-day Uganda before the establishment of the Republic of Uganda, and the history of that country once it was established. Evidence from the Paleolithic era shows humans have inhabited Uganda for at least 50,000 years. The forests of Uganda were gradually cleared for agriculture by people who probably spoke Central Sudanic languages.

The Luo, are several ethnically and linguistically related Nilotic ethnic groups that inhabit an area ranging from Egypt and Sudan to South Sudan and Ethiopia, through Northern Uganda and eastern Congo (DRC), into western Kenya, and the Mara Region of Tanzania. Their Luo languages belong to the western branch of the Nilotic language family.
