Mesopotamia saw the earliest known form of complex civilization. It was developed approximately 10,000 years ago between the Tigris and Euphrates river. It was a climatically favorable land where the first human settlements originated.\cite{mesopotamia} Associated with Mesopotamia are ancient cultures like Sumerians, Assyrians, Akkadians, and Babylonians. It is believed that Sumerian civilization took place around 4000 BC - or 6000 years ago, which made it the first urban civilization in the region. The Sumerians developed irrigation in agriculture, domestication of animals and siege warfare. The invention of the wheel is among their most important contributions to the development of society, since it allowed for a host of innovations. Many important innovations accredited to the Sumerians influence our lives even today. \cite{civilizations}
