The Safavid were a relatively peaceful empire based around Iran.
Explanation:
The Safavid empire was a major power player in the Iranian area and the larger peninsula of the middle east during the 15th to 18th century when their predominantly shia empire fell.
Most of the energy of the empire did go to the promotion of shia Islam in the area they ruled and its neighboring states that was the middle east which it did try to take over with less avail.
Due to less territorial expanse, the empire remained quite stable.
