WATCH | The Most Luxurious Party On Earth

The largest gathering of monarchs and leaders of state in modern history took place in 1971, in the middle of the Iranian desert. The celebration meant to commemorate the 2500th anniversary of the Persian empire's foundation, and its host, Iran's Shah Mohammed Reza Pahlavi, spent hundreds of millions of dollars to impress them.

The party is an effort to present the world the face of a modern, advanced, and free Iran. The event aimed to showcase Iran's pre-Islamic heritage and to elevate its founder, Cyrus the Great, to the status of worldwide hero.
