Which region is associated with the Sumerians who are known for their advanced technology and economic systems?

The Sumerians are closely associated with Southern Mesopotamia, which is situated in the region of modern-day Iraq. This area is recognized as one of the cradles of civilization where the Sumerians established some of the world's first urban centers around 3000 BCE. They developed advanced technologies such as cuneiform writing, which is one of the earliest forms of written expression, and sophisticated irrigation systems that enhanced agricultural productivity.

Additionally, the Sumerians implemented complex economic systems, including trade networks that connected them with neighboring cultures. Their advancements in mathematics and astronomy also laid the groundwork for future civilizations. Southern Mesopotamia's geographical location, with fertile land supported by the Tigris and Euphrates Rivers, was instrumental in the growth of the Sumerian society and its technological and economic innovations. This combination of factors makes Southern Mesopotamia distinctly recognized as the heart of Sumerian civilization.
