Parsi or Persian was the language of the Parsa people who ruled Iran between 550 - 330 BCE. It belongs to what scholars call the Indo-Iranian group of languages. It became the language of the Persian Empire and was widely spoken in the ancient days ranging from the borders of India in the east, Russian in the north, the southern shores of the Persian Gulf to Egypt and the Mediterranean in the west.
Over the centuries Parsi has changed to its modern form and today Persian is spoken primarily in Iran, Afghanistan, Tajikistan and parts of Uzbekistan. It was the language of the court of many of the Indian kings till the British banned its use, after occupying India in the 18 century. The Mogul kings of India had made Persian their court language. Engraved and filled with gold on walls of Delhi's Red Fort is the sentence "Agar Ferdows dar jahan ast hamin ast o hamin ast o hamin ast"; - 'If there is a paradise on earth it is here it is here it is here.'
Although the name of the language has been maintained as Persian or Parsi or its Arabic form Farsi (because in Arabic they do not have the letter P) the language has undergone great changes and can be categorized into the following groups.
1. Old Persian
2. Middle Persian
3. Classical Persian
4. Modern Persian
Old Persian is what the original Parsa tribe of the Hakahmaneshinian (Achaemenid) era spoke and they have left for us samples carved on stone in cuneiform script.
Middle Persian is the language spoken during the Sasanian era also known as Pahlavi. We have plenty of writings from that era in the form of religious writings of the Zarathushti religion, namely the Bundahish, Arda Viraf nameh, Mainu Khared, Pandnameh Adorbad Mehresfand etc.
