Abstract
The Arab invasion of Iran is one of the most important events that occurred in the ancient country of Iran. The Arabs were able to achieve unity and unity in the shadow of the new religion and the orders of the Holy Prophet (PBUH). In 622 AD, one problem after another was solved and a powerful group was formed based on the religion of Islam. ،. Iran was defeated by the three small Arab armies during the three battles of Jalalada, Nahavand, and Qadisiyah, and as a result, the Iranians fell from captivity to servitude. Eventually, the Arab armies conquered the northern regions of Iran and Tabarestan, which, of course, were very difficult for the Arabs to conquer due to the climate and the way of view of its people, especially the uprisings that took place in these areas in the early Islamic centuries. , Including the uprising of Maziar Ibn Qarn, which was the confrontation of the people of Mazandaran and the northern regions of Iran against the Arabs, in order to preserve the national identity and the ancient heritage of our ancestors. To this day, however, the people's view of the Arab conquest of Iran has been such that, with the arrival of Arab troops on Iranian soil, the people have at once accepted and embraced this religion and belief.
