Passage: State formation began during this era and perhaps even earlier. Various small city-states arose along the Nile. Centuries of conquest then reduced Upper Egypt to three major states: Thinis, Naqada, and Nekhen. Sandwiched between Thinis and Nekhen, Naqada was the first to fall. Thinis then conquered Lower Egypt. Nekhen's relationship with Thinis is uncertain, but these two states may have merged peacefully, with the Thinite royal family ruling all of Egypt. The Thinite kings were buried at Abydos in the Umm el-Qa'ab cemetery.

Question: Where were the rulers of Egypt laid to rest?
