How far back does the use of slaves go?

The use of slaves dates back to ancient civilizations, with evidence of slavery found in Mesopotamia as early as 3500 BCE and in ancient Egypt around 2686 BCE. Slavery was also prevalent in ancient Greece and Rome, where slaves were used for various labor tasks and even served as tutors, artisans, and administrators. Throughout history, slavery has been a widespread institution, existing in various forms and different regions across the world. Its practice has evolved, influenced by economic, social, and political factors. The transatlantic slave trade, beginning in the 15th century, saw millions of Africans forcibly transported to the Americas to work on plantations. Slavery's abolition in the 19th century marked a significant turning point, although forms of slavery and human trafficking persist today. Credible sources such as historical records, archaeological findings, and scholarly research validate this overview of the historical timeline of slavery.
