Answer:
North Africa - Alexandria and Carthage
Explanation:
The trade routes between countries positioned on the Mediterranean is called the Mediterranean sea complex. It included boat trade between Europe with North Africa and the near East.
Slaves in Europe were mostly foreigners. They were traded to Europe from North Africa. They were likely to be traded from the city of Alexandria in Egypt and to Carthage.
The position of the slave was not based on race like it was in more recent history, but on the country of origin - most of them were captioned and were the people from conquered counties. Still, some of the enslaved people were victims of piracy and robbery and were later sold at slave markets around the European cities.
