What is the time frame of slave trade?

The transatlantic slave trade primarily occurred from the late 15th century to the mid-19th century, peaking between the 17th and 18th centuries. It began around the 1500s, when European nations started transporting enslaved Africans to the Americas. The trade officially ended in most countries by the mid-1800s, although illegal trafficking continued for some time afterward. Overall, this dark chapter in history spanned approximately 400 years.
