The Second Dynasty, maintained the war records of raids into Nubia. None of the raid efforts were large scale or resulted in permanent conquest, but they are indicative of a desire for the wealth of Nubia. Another large exploit of the Egyptians during the Second Dynasty is the shift of a power center from Abydos to Memphis. This shift, due largely in part to resources, could also possibly have been due to the cult of the Sun god Ra beginning during this period, and also due to a want for greater political control by the king. By the end of the 2nd Dynasty an end to political opposition of north and south established a basic economic, religious and political system, which lasted well into dynasties to come, and paved the way for the more affluent Third Dynasty.
