Throughout history, Persia has generally been an empire, one whose fortunes varied enormously. In ancient times, Persia controlled most of what we now call the Middle East, and came close to conquering Greece. A few centuries later, Alexander of Macedonia conquered (among other things) the entire Persian Empire. Later, Persia was conquered by the Arabs in the wild expansion of Islam in the centuries immediately after the Prophet; Persian and other languages of the region are still written with the Arabic alphabet. About 1250, Persia was overrun by the Mongols. Marco Polo passed through just after that, learned Persian, and wrote extensively of the region.
At other times, Persia conquered many of her neighbors. Her empire often included much of what we now call Central Asia (Polo counted Bokhara and Samarqand as Persian cities), and sometimes various other areas. A few generations after the Mongols took Persia. The dynasty they founded there took all of Afghanistan and Pakistan, and most of India. The Indian term "Moghul" for some of their rulers is from "Mongol", via Persia. Even in periods when she did not rule them, Persia has always exerted a large cultural influence on her neighbors, especially Afghanistan and Central Asia.
The Safavid dynasty re-united Persia as an independent state in 1501, established Shi'a Islam as the official religion, and ushered in a golden age of Persian culture. They were overthrown in 1736 by Nadir Shah, the last great Asian conqueror, who expanded the Empire to again include Afghanistan and much of India. His short-lived dynasty and its successor lasted until 1795. Then the Qajar dynasty ruled 1795-1925, a period of heavy pressure from foreign powers, notably Britain and Russia who jointly occupied Iran during World War I. In 1906, Qajar rule became a constitutional monarchy and the Majlis (Persian for parliament) was established.
