Egypt is located in northeast Africa, with most of the country consisting of desert despite being located along the Nile River, the second longest river in the world. The ancient Egyptians built massive pyramids to serve as tombs for pharaohs, who were believed to be both human and gods. Important pharaohs included Tutankhamun, whose tomb contained hundreds of gold objects, and Cleopatra, the last active ruler of Egypt who took her own life after the defeat of her ally Mark Antony. The ancient Egyptians wore linen clothing appropriate for the hot climate and revered animals like cats that were seen as protective.
