Sasanid Principalities
During the first three decades of Arab rule to Iran, a Sasanid prince called Dabooyeh, a descendant of Peerooz established a little principality on the northern part of the country. His territory was located between the Alburz mountains and Caspian sea, an area called Deylaman. The people in Deylaman were Zoroasterian and they did not convert to Islam for a long time(since 1000 AD), so they supported Dabooyeh and his successors, who were also Zoroasterian. He was able to keep his territories independence, and he did not let the Arabs come to his land.
Dabooyeh’s dynasty ruled Deylaman for 150 years. After that, two other branches of Sasanid princes divided Dabooyeh’s territory between themselves. One of them was called “Padoospanian”(descendants of Dabooyeh’s brother, Padoospan) and another one called, Bavandi(descendants of Kavoos, brother of Khosro I). These two dynasties later converted to Islam(in the 11th century AD), but they never lost their territories to Arabs, and they ruled it for 950 years! Longest of any dynasty in Iranian history.
