The Early Dynastic Period, also known as Archaic Period or the Thinite Period (from Thinis, the hometown of its rulers), is the era of ancient Egypt that immediately follows the unification of Upper and Lower Egypt in 3150 BC. It is generally taken to include the First Dynasty and the Second Dynasty, lasting from the end of the archaeological culture of Naqada III until 2686 BC, or the beginning of the Old Kingdom. With the First Dynasty, the Egyptian capital moved from Thinis to Memphis, with the unified land being ruled by an Egyptian god-king. In the south, Abydos remained the major centre of ancient Egyptian religion; the hallmarks of ancient Egyptian civilization, such as Egyptian art, Egyptian architecture, and many aspects of Egyptian religion, took shape during the Early Dynastic Period.
Before the unification of Egypt, the land was settled with autonomous villages. With the early dynasties, and for much of Egypt's history thereafter, the country came to be known as "The Two Lands" (referencing Upper and Lower Egypt). The pharaohs established a national administration and appointed royal governors, and buildings of the central government were typically open-air temples constructed of wood or sandstone. The earliest Egyptian hieroglyphs appear just before this period, though little is known of the spoken language that they represent.
By about 3600 BC, Neolithic Egyptian societies along the Nile 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 period. 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.
Concurrent with these cultural advances, a process of unification of the societies and towns of the upper Nile River, or Upper Egypt, occurred.
