1. Europe: Although slavery had largely declined in most parts of Europe by the 19th century, serfdom and other forms of forced labor still persisted in some areas. For instance, serfdom was abolished in Russia in 1861.
2. Ottoman Empire: Slavery was prevalent in the Ottoman Empire, which spanned across present-day Turkey, the Balkans, North Africa, and parts of the Middle East. The Ottoman slave trade involved capturing and selling individuals from various conquered territories.
3. Spanish Colonies in the Americas: Slavery existed in the Spanish colonies throughout Latin America, including present-day Mexico, Central America, South America, and the Caribbean. The Spanish used both African slaves and indigenous peoples for forced labor.
4. Portuguese Colonies in the Americas: Similar to the Spanish colonies, slavery existed in the Portuguese colonies in Brazil and other parts of South America. Brazil was one of the largest importers of African slaves during that time.
5. French Colonies in the Americas: The French colonies in the Caribbean, such as Saint-Domingue (now Haiti), relied heavily on African slaves for labor in sugar plantations. The French slave trade was significant, particularly in the 18th century.
6. British Colonies in the Caribbean and the Americas: Apart from the United States, slavery was practiced in other British colonies in the Caribbean, such as Jamaica and Barbados, as well as in British territories in North America, like the Bahamas and Bermuda.
7. Indian Ocean Slave Trade: Slavery was also present in the Indian Ocean region. Arab slave traders operated extensively, capturing and selling individuals from East Africa to various parts of the Middle East, India, and Southeast Asia.
8. Trans-Saharan Slave Trade: Historically, slavery existed in parts of Africa, with various African kingdoms and empires participating in the trans-Saharan slave trade. This trade involved the selling of captured individuals across the Sahara Desert to markets in North Africa and the Middle East.
These examples illustrate the widespread existence of slavery during the same time as American slavery, with different regions and cultures engaging in this inhumane practice to varying degrees.
