Safavid Empire
Originally of Kurdish origin, which began as a Sunni mystical order, which was  non-tribal, the Safavids emerged as a hereditary lineage of Sufi sheiks centred in Ardabil, belonging to the Shafi'i school and possibly of Kurdish origin.  The Safavid shahs spoke Azeri brand of Turkic at the court like the qizilbash,. After the capital was moved to Isfahan, Persian began to be spoken in the palace.
