The Hyksos controlled Egypt from roughly 1650 to 1550 BC and it was likely one of their rulers who was the pharaoh “who knew not Joseph” and put the Israelites in slavery (Exod 1:8).  From Discovery News:

Radar imaging in Egypt’s Nile Delta has unveiled the outlines of a buried city that was the stronghold of foreign occupiers some 3,500 years ago, Egypt’s Supreme Council of Antiquities announced Monday.
Discovered by a team of Austrian archaeologists in Tell el-Daba in the northeastern Nile Delta, the ruins belong to the southern suburban quarters of Avaris, the capital of the Hyksos kings who formed Egypt’s 15th dynasty.
Known as the “rulers of foreign countries” (probably of Asiatic roots),  the Hyksos infiltrated Egypt and came to dominate the Nile valley for over a century during the Second Intermediate Period (1664-1569 B.C.).
From their strategic capital, Avaris, these foreign rulers are credited with introducing horse-drawn chariots into Egypt and controlling the lucrative trade routes with the Near East and the Mediterranean world.

Just when did Egyptian pharaohs such as King Tut and Rameses II rule? Historians have heatedly debated the exact dates. Now a radiocarbon study concludes that much of the assumed chronology was right, though it corrects some controversial dates and may overturn a few pet theories.
“This is an extremely important piece of research that shows clearly that historical dating methods and radiocarbon dates are compatible for ancient Egypt,” says Kate Spence, an archaeologist at the University of Cambridge in the United Kingdom.
Egyptian records, such as the writings of the 3rd century B.C.E. historian Manetho and inscriptions found at key sites such as Saqqara and Karnak, provide what are called “floating chronologies” because they are internally consistent but not anchored to absolute dates. On the other hand, they sometimes refer to astronomical events whose dates can be calculated today. Thus, scholars are confident that they are not wildly off the mark. But it’s difficult to be precise. For example, the first known pyramid, the Step Pyramid at Saqqara, was built as a tomb for King Djoser, and historians usually put the beginning of his reign between 2667 and 2592 B.C.E. But one recent paper by Spence, based on astronomical calculations, put it as much as 75 years later. Radiocarbon dating has been too imprecise to resolve these contradictions because in this period it usually has error ranges of between 100 and 200 years.

One major controversy remains unresolved: the timing of the massive eruption of the volcanic island of Thera in the Aegean Sea, which transformed the history of the eastern Mediterranean and has important implications for understanding the relationship between Egypt and the Minoans, another powerful culture of the time. Previous radiocarbon dating suggests that the eruption took place at least 100 years before the New Kingdom began, which the new dating puts at no earlier than 1570 B.C.E. But radiocarbon and historical dating by University of Vienna archaeologist Manfred Bietak’s team at Tell el-Dab’a in Egypt has concluded that the Thera eruption took place during the New Kingdom era.
