Global trade routes in the Atlantic, Pacific, and Indian Oceans significantly impacted and codified existing social structures in various regions.
1. **Atlantic Ocean (Europe and the Americas):** The Atlantic slave trade not only created a racial hierarchy in the Americas but also reinforced class divisions in Europe, with wealth concentrated in the hands of those involved in the trade.
2. **Indian Ocean (East Africa and South Asia):** Trade routes facilitated the spread of Islam and the establishment of powerful merchant classes in cities like Zanzibar and Gujarat, solidifying social stratifications based on commerce and religion.
These trade routes connected different parts of the world, leading to profound economic, social, and cultural changes.
