Question: Ancient Egypt was an ancient civilization of eastern North Africa, concentrated along the northern reaches of the Nile River in Egypt, its history occurred in a series of stable "kingdoms", separated by periods of relative instability known as "intermediate periods", the history of ancient Egypt spans the period from the early prehistoric settlements of the northern Nile valley to the Roman conquest, in what year?

<P0-S0> The history of ancient Egypt spans the period from the early prehistoric settlements of the northern Nile valley to the Roman conquest, in 30 BC. <P0-S1>  The Pharaonic Period is dated from the 32nd century BC, when Upper and Lower Egypt were unified, until the country fell under Macedonian rule, in 332 BC. <SEP> <P1-S0> Ancient Egypt was a civilization of ancient Northeastern Africa, concentrated along the lower reaches of the Nile River in the place that is now the country Egypt. <P1-S1>  It is one of six historic civilizations to arise independently. <P1-S2>  Egyptian civilization followed prehistoric Egypt and coalesced around 3150 BC (according to conventional Egyptian chronology) with the political unification of Upper and Lower Egypt under Menes (often identified with Narmer). <P1-S3>  The history of ancient Egypt occurred as a series of stable kingdoms, separated by periods of relative instability known as Intermediate Periods: the Old Kingdom of the Early Bronze Age, the Middle Kingdom of the Middle Bronze Age and the New Kingdom of the Late Bronze Age. <SEP> <P2-S0> Ancient Egypt was an ancient civilization of eastern North Africa, concentrated along the northern reaches of the Nile River in Egypt. <P2-S1>  The civilization coalesced around 3150 BC with the political unification of Upper and Lower Egypt under the first pharaoh, and it developed over the next three millennia. <P2-S2>  Its history occurred in a series of stable "kingdoms", separated by periods of relative instability known as "intermediate periods". <P2-S3>  Ancient Egypt reached its pinnacle during the New Kingdom, after which it entered a period of slow decline. <P2-S4>  Egypt was conquered by a succession of foreign powers in this late period, and the rule of the pharaohs officially ended in 31 BC when the early Roman Empire conquered Egypt and made it a province. <P2-S5>  Although the Egyptian military forces in the Old and Middle kingdoms were well maintained, the new form that emerged in the New Kingdom showed the state becoming more organized to serve its needs. <SEP> <P3-S0> The Kerma culture or Kerma kingdom was an early civilization centered in Kerma, Sudan. <P3-S1>  It flourished from around 2500 BCE to 1500 BCE in ancient Nubia, located in Upper Egypt and northern Sudan. <P3-S2>  The polity seems to have been one of a number of Nile Valley states during the Middle Kingdom of Egypt. <P3-S3>  In the Kingdom of Kerma's latest phase, lasting from about 1700–1500 BCE, it absorbed the Sudanese kingdom of Sai and became a sizable, populous empire rivaling Egypt. <P3-S4>  Around 1500 BCE, it was absorbed into the New Kingdom of Egypt, but rebellions continued for centuries. <P3-S5>  By the eleventh century BCE, the more-Egyptianized Kingdom of Kush emerged, possibly from Kerma, and regained the region's independence from Egypt.
