Sneferu was the first pharaoh of the fourth dynasty and he ruled from about 2613 BC to 2589 BC. He is famous for building many pyramids, including the large pyramid at Maidum.
Tutankhamen ruled Egypt during the eighteenth dynasty, from about 1334 BC to 1325 BC. He was only eight or nine years old when he became pharaoh. Tutankhamen only became famous after his death, because of the large amount of treasure that was found in his tomb.
