Look at the big picture. What happened was Hyksos brought the chicken industry to Egypt. Industrial chicken farming. More protein, more population growth. Bigger government and all the risks that go with it. In 1700 BC the Hyksos brought the hybrid olive to Egypt and again change everything. Not just in Egypt but all of Europe.
So, you found trouble “around 2200 BC.” That’s about the time Abraham, friend of El and Yahweh. All from around the Ur area. Came to Egypt’s Middle Kingdom and used his very rare skills of making glass to form a leadership power. Glass at that time was more valuable than gold. Abraham had first went to Ethiopia then to the Middle Kingdom. I would do some research into what affects Abraham had in causing civil war. Abraham is thought to have arrived in Egypt around 2150 BC. So, 2200 BC would have been about the time of his death.
