In 1971, the Persian Empire celebrated its 2,500th birthday as Shah Reza Pahlavi of Iran
gave a four-day celebration costing $100 million. The focal point of the event was a huge
banquet, the banquet hall being a gigantic silk tent lighted with $840,000 worth of
colored lights! The guest list matched the occasion: the Shah invited more than 600
dignitaries from 69 nations.
