The Transatlantic Slave Trade was a trading pattern that most European Powers at the time followed to maximize profits from the exploits of the New World. These powers found that they could cultivate cash crops like sugar and mine for valuable minerals in South America and the Caribbean. These jobs were labor intensive and required a lot of people to do so. Natives weren’t reliable since they died easily of Europeans diseases. Europeans found an easy labor force and traded other goods with tribes for men who were taken on the Middle Passage and to such locations to work.
Sumerians believed that not only were there high gods but also personal Gods that relayed the prayer to the high Gods. Every head of a house prayed to their God would intercede for them and their family and in exchange, they offered prayer, supplications and sacrifice while still worshiping other gods in the pantheon.
After many people began reading and interpreting the Bible, they began to form their own interpretations of God and started putting less focus on the Catholic church.
