The document summarizes information about the ancient Minoan civilization that originated on the island of Crete around 2800 BCE. The Minoans were a seafaring people who built grand palaces, like the palace at Knossos, their capital city. They traded extensively by sea and had advanced architecture, plumbing, and infrastructure. The Minoans disappeared around 1450 BCE, possibly due to a large tsunami and volcanic eruption. The Mycenaeans then took over rule of the Mediterranean sea, learning much of their advanced culture from the Minoans.
