In 331 BCE, Alexander The Great invaded Egypt and was met with no resistance. The Persian satrap surrendered and the Egyptians, who were tired of Persian rule, welcomed the Macedonians. In the spring of 331 BCE he made a pilgrimage to the great temple and oracle Amon-ra. At the temple, he was welcomed by the priests and spoke to the oracle. The priest told him that he was a son of Zeus Ammon, destined to rule the world, and this must have confirmed in him his belief of divine origin. Alexander remained in Egypt until the middle of 331, and then returned to Tyre before facing Darius.
