Pasargadae (Persian: پاسارگاد‎ Pāsārgād), the capital of Cyrus the Great (559–530 BC) and also his last resting place, was a city in ancient Persia, and is today an archaeological site and one of Iran's UNESCO World Heritage Sites.

Cyrus the Great began building his capital in 546 BCE or later; it was unfinished when he died in battle, in 530 or 529 BCE. The remains of the tomb of Cyrus' son and successor, Cambyses II, has been found in Pasargadae, near the fortress of Toll-e Takht, and identified in 2006.

Pasargadae remained the Persian capital until Cambyses II moved it to Susa; later, Darius founded another in Persepolis. The archaeological site covers 1.6 square kilometres and includes a structure commonly believed to be the mausoleum of Cyrus, the fortress of Toll-e Takht sitting on top of a nearby hill, and the remains of two royal palaces and gardens. Pasargad Persian Garden provide the earliest known example of the Persian chahar bagh, or fourfold garden design (see Persian Gardens).

Cyrus II of Persia (Old Persian: Kuruš (c. 600 BC or 576 BC–530 BC), commonly known as Cyrus the Great, also known as Cyrus the Elder, was the founder of the Achaemenid Empire. Under his rule, the empire embraced all the previous civilized states of the ancient Near East, expanded vastly and eventually conquered most of Southwest Asia and much of Central Asia, parts of Europe and the Caucasus. From the Mediterranean sea and Hellespont in the west to the Indus River in the east, Cyrus the Great created the largest empire the world had yet seen. He also pronounced one of the first historically important declarations of human rights via the Cyrus Cylinder sometime between 539-530 BCE.

The reign of Cyrus the Great lasted between 29 and 31 years. Cyrus built his empire by conquering first the Median Empire, then the Lydian Empire and eventually the Neo-Babylonian Empire. Either before or after Babylon, he led an expedition into central Asia, which resulted in major campaigns that were described as having brought "into subjection every nation without exception". Cyrus did not venture into Egypt, as he himself died in battle, fighting the Massagetae along the Syr Darya in December 530 BC. He was succeeded by his son, Cambyses II, who managed to add to the empire by conquering Egypt, Nubia, and Cyrenaica during his short rule.
