Minos

Son of Zeus and Europa, Minos was king of Crete and many of the Aegean islands and housed in the Palace of Knossos. He was married to Pasiphae, and they had several children, amongst others the son Androgeos and the daughters Acacallis, Ariadne and Phaedra.
He was ruler of the seas and had gotten his laws straight from Zeus, who also was connected to Crete. According to the Odyssey he spoke with Zeus every nine years or for nine years.
Minos was considered a ruler of peace, and he founded many cities. But he could also be harsh. When his son Androgeos had won the Panathenaeic Games the king Aegeus sent him to fight the bull from Marathon which killed him. Outraged, Minos went to Athens to revenge his son, and on the way he camped at Megara. The king who lived there, Nisos, was alive thanks to his purple hair. His daughter Scylla fell in love with Minos and cut of her fathers hair so that Minos could conquer the city. After he had done this, he tied the treacherous Scylla to his boat and dragged her until she had drowned.
On arriving in Attica, he asked Zeus to punish the city, and the god struck it with plague and hunger. An oracle told the Athenians to meet any of Minos' demands if they wanted to escape the revenge. Minos then asked Athens to send seven boys and seven girls to Crete ever nine years to be sacrificed to the Minotaur.
As a punishment for Minos refusing to sacrifice a certain bull, Poseidon made his wife Pasiphae fall in love with it, giving birth to the Minotaur. Minos had his architect Daedalus construct a labyrinth in which he hid the monster.
The Minotaur was defeated by the hero Theseus with the help of Minos daughter Ariadne.
Daedalus had also helped him, and Minos punished him by locking him and his son Icarus into the labyrinth. They fled by making wings, but only Daedalus made it to Sicily alive. There, he sought refuge under the king, whose daughters killed Minos when he came to get Daedalus.
After Minos's death on Sicily he became a judge of the dead in the underworld.
