Was Nizams Shia or Sunni?

Though Asaf Jahs (Nizams), rulers of erstwhile Hyderabad State, were Sunni Muslims, they continued to patronise the observance of Muharram. It was during their time that special colonies for Shias were built in Darulshifa and surrounding areas. It was during the Asaf Jahi period that several ashurkhanas were built.
