Second Dynasty of Egypt

The Second Dynasty of Egypt (c. 2890 - c. 2670 BCE) rose from the turmoil which ended the first and was marked by uprisings (or, at least, internal difficulties) throughout. The precise cause of this civil unrest is unclear as sources for this period are confused and even the dates of the rulers are unreliable. Some of the names of the kings given by Manetho are not supported by any archaeological evidence and may be duplications of earlier rulers under other names. During the Second Dynasty, developments in culture and military expansion continued, especially in Nubia, but war between Upper and Lower Egypt seems to have occupied many of the rulers and the nation may even have divided during this time.
