Answer: The answer is: surplus.
Explanation: Since the Sumerian civilisation developed between rivers in the fertile plain, therefore, thanks to agriculture, combined with the rainy seasons during the year, meant that they were able to produce large quantities of food. That food was necessary for life, and any excess food could be exchanged for some other good, which was in fact a precondition for development. Every surplus of food, growing bigger and bigger, meant an exchange for something else that was needed, and over time, it had grown to such an extent that this exchange meant wealth, power and dominance in the ancient world.
Of course, this exchange of surplus food for other goods contributed to the development of trade with their neighbours, which was a prerequisite for the development of the empire. Thus, a trading system was developed that included established trade canals and their development and promotion, as well as writing trade agreements with a wedge-shaped letter, for easier, faster and more efficient trade.

Equiano Olaudah was an English philosopher and writer. He used to be enslaved but he bought his own freedom. He grew up and wrote about his experiences and encounters as an enslaved child. He was a major figure in the campaign to get rid of the slave trade immediately, and he was sold to start being a slave when he was only 11 years old. He even wrote his own autobiography titled ‘The Interesting Narrative of the Life of Olaudah Equiano or Gustavus Vassa, the African.’ He was a part of the “Sons of Africa,” and his autobiography that he self-published spread to be the most detailed account of the Middle Passage from a firsthand account of someone actually traveling along the route.
