Cyrus the Great was the founder of the Achaemenid Empire, the first Persian Empire. His regal titles in full were The Great King, King of Kings, King of Persia, King of Anshan, King of Media, King of Babylon, King of Sumer and Akkad, and King of the Four Corners of the World.

The Achaemenid Empire, founded by Cyrus the Great, is the largest empire the world had yet seen. Ranging at its greatest extent from the Balkans and Eastern Europe proper in the west to the Indus Valley in the east, it was larger than any previous empire in history. Incorporating various peoples of different origins and faiths, it is notable for its successful model of a centralised, bureaucratic administration through satraps under the King of Kings, for building infrastructure such as road systems and a postal system, the use of an official language across its territories, and the development of civil services and a large professional army. The empire's successes inspired similar systems in later empires.

Tomb of Cyrus the Great is located one kilometer from Pasargadae palaces. In 529 B.C., Cyrus invaded the Scythian clans in Central Asia and he was killed in the battle with the Massagetai. He was buried in this tomb, which was most likely to be built before his death and under his own command. Tomb of Cyrus is a simple structure with unique architecture that is constructed of yellowish-white calcareous stones with the total height of over 11 meters. This structure is composed of two sections: one section is a rectangular stone platform with six steps and the other section is a chamber with a gable roof over the sixth step. Tomb of Cyrus the Great has been registered in UNESCO World Heritage Center.
