History of lower Egypt?

It was divided into twenty districts called nomes, the first of which was at el-Lisht. Because Lower Egypt was mostly undeveloped scrubland, filled with all types of plant life such as grasses and herbs, the organization of the nomes underwent several changes.

The capital of Lower Egypt was Memphis. Its patron goddess was the cobra goddess Wadjet. Lower Egypt was represented by the Low Red Crown Deshret, and its symbols were the papyrus and the bee.

By about 3600 BC, Neolithic Egyptian societies along the Nile River had based their culture on the raising of crops and the domestication of animals. Shortly after 3600 BC Egyptian society began to grow and advance rapidly toward refined civilization. A new and distinctive pottery, which was related to the pottery in the Southern Levant, appeared during this time. Extensive use of copper became common during this time. The Mesopotamian process of sun-dried bricks, and architectural building principles—including the use of the arch and recessed walls for decorative effect—became popular during this time.

Concurrent with these cultural advances, a process of unification of the societies and towns of the upper Nile River, or Upper Egypt, occurred. At the same time the societies of the Nile Delta, or Lower Egypt also underwent a unification process. Warfare between Upper and Lower Egypt occurred often. During his reign in Upper Egypt, King Narmer defeated his enemies in the Delta and merged the Kingdoms of Upper and Lower Egypt under his single rule.
