Qazvin

Qazvin, in northwestern Iran, was a significant medieval city and briefly a Safavid capital in the 16th century. The hadith compiler Ibn Majah (d. 887), author of one of the six canonical Sunni collections, was born there and took his nisba al-Qazwini; the philosophers Mir Damad (d. 1631) and Mulla Sadra were active in its scholarly milieu.
