context_page_description: The 2,500-year celebration of the Persian Empire, officially known as the 2,500th Year of the Foundation of the Imperial State of Iran, consisted of an elaborate set of festivities that took place on 12–16 October 1971 to celebrate the anniversary of the founding of the Imperial State of Iran and the Achaemenid Empire by Cyrus the Great. The intent of the celebration was to demonstrate Iran's ancient civilization and history and to showcase its contemporary advances under His Imperial Majesty Mohammad Reza Shah, the last Shah of Iran.
  Some later historians came to think that this excess contributed to events that resulted in the Iranian Revolution and eventual replacement of the Persian monarchy with an Islamic republic under the Grand Ayatollah Ruhollah Khomeini, the leader of the revolution, who was supported by a wide range of people, including various leftist and Islamist organizations, and student movements. The event has been described as the most expensive party ever held.
