Persia

"An ancient empire, extending from the Indus to Thrace, and from" the Caspian Sea to the Red Sea and the Persian Gulf. The "Persians were originally a Medic tribe which settled in Persia," "on the eastern side of the Persian Gulf. They were Aryans, their" language belonging to the eastern division of the Indo-European "group. One of their chiefs, Teispes, conquered Elam in the time" "of the decay of the Assyrian Empire, and established himself in" the district of Anzan. His descendants branched off into two "lines, one line ruling in Anzan, while the other remained in" "Persia. Cyrus II., king of Anzan, finally united the divided" "power, conquered Media, Lydia, and Babylonia, and carried his" "arms into the far East. His son, Cambyses, added Egypt to the" "empire, which, however, fell to pieces after his death. It was" "reconquered and thoroughly organized by Darius, the son of" "Hystaspes, whose dominions extended from India to the Danube."
