Arabism, despite differing circumstances, saw the Arab current of Arabism continue to flow into Sudan until a large part of it became Arab. The northern gateway played a major role in Sudan's discovery of its Arabism and Islam, as this passage was the source from which the majority of Arab tribes who settled in Sudan came. This is because the northern passage gained its importance from Egypt's geographical location, a location that links it closely to Arab elements. The Sinai Peninsula played a facilitating role in this regard.

This is because Sinai was not merely a passage or a gate through which Arab migrations entered the Nile Valley, but rather it was, in reality, an integral part of the Nile Valley and a bridge connecting Asia and Africa. It played an important role from the beginning of Egyptian history, being one of the two main routes from which Arab migrations came to the Nile Valley.

This is because the Sinai desert did not stand as a barrier between the nomadic Arab tribes and their flow into the Nile Valley, especially those Arab tribes spread across the north of the Arabian Peninsula, Palestine, and Jordan, and their migrations to the Nile Valley. Rather, it is rare to find an Arab tribe from the Bedouin tribes of Sinai that does not have kinship ties with one or more tribes from those lands.

And so, during the early Islamic eras, Arab tribes began to cross Sinai in a way not witnessed in previous historical periods. From Sinai, the tribes entered the land of Egypt. Given the ancient Arab tribes and this Arab influx into Islamic Egypt, and as a result, the passages and arteries through which Arab blood and Arab-Islamic culture flowed to Sudan and the Nile Valley became established, excluding those few Arab migrations that reached Sudan directly across the Red Sea.
