In 2900 BC, Egypt was in the early dynastic period, also known as the "pre-dynasty" or "zero dynasty". This was the first period in the history of ancient Egypt and marked the transition from a tribal society to a centralized state.
During this period, the southern ruler of Egypt, Narmer (sometimes referred to as Menes), began to make his mark. It is believed that Narmer was the first ruler to unify the entire Nile Delta, as well as northern Egypt. His reign marked the transformation of ancient Egypt from a confederation of tribes to a unified state.
Narmer's reign also marked the beginning of the development of a centralized system in ancient Egypt. He built a powerful *** and consolidated his rule through a series of political and military means. In addition, Narmer also started building great structures such as pyramids to show his power and glory.

In 2900 BC, the Sumerian region entered an era of city-states vying for supremacy. During this period, several larger cities emerged in the Sumerian region, such as Elidu, Kish, Lagash, Uruk, your, and Nipur. These cities began to fight each other for almost a thousand years over water rights, roads, and nomadic tribute.
During this period of hegemony, the various city-states competed with each other in an attempt to expand their power and influence. Of these, Uruk and Lagash were the two most powerful city-states. Uruk, under the leadership of Gilgamesh, showed signs of his gradual rise to become the sumerian hegemon through warfare and diplomacy.
However, due to the relative balance of power among the various city-states, no single city-state was able to complete the unification. The Sumerians were weakened by constant wars and fighting, which provided opportunities for later conquerors.
During this period of hegemony, the social economy of the Sumerian region was also greatly affected. ** and communication between the various city-states were hampered, and the development of agriculture and livestock was restricted. At the same time, the strife between the city-states also led to the movement of people and cultural exchanges, which also had a certain impact on the spread and development of Sumerian culture.
European regions: In 2900 BC, there were relatively few historical events in Europe, as much of Europe was still in the prehistoric period, the Early Bronze Age. However, there are still some events and trends to watch out for. First of all, many bronze artifacts appeared throughout Europe during this period, marking the dawn of the Bronze Age.
City-states began to emerge in the Aegean region. These city-states are city-centric, independent and engage in frequent exchanges of cultural exchange with each other. The rise of this city-state system laid the foundation for the later development of Greek civilization and Western civilization.
In addition, around 2900 BC, there was also the development of agriculture and animal husbandry in some parts of Europe. People began to grow various crops such as wheat, barley, beans, etc., and domesticated domestic animals such as cattle, sheep, and pigs. These agricultural and livestock developments have provided people with a more stable diet**, as well as population growth and social prosperity.
