Huwala also collectively referred to as Bani Huwala, is a blanket term usually used to refer to Iranian Arabs of tribal lineage who initially migrated to Iran in the 13th and 14th century and intermixed with the indigenous population of older Arabic-speaking background. Such migrations continued till around 19th century to the area which is now Iran's Hormozgan Province and Fars Province, mainly Bandar Abbas, Qishm, and the mainland near Bandar Lengeh. The Huwala follows Sunni Islam, as opposed the majority Persian Twelver Shia and similar to Sunni Peninsular Arabs. Most of the Huwala have remigrated back to the Arabian Peninsula between late 19th century and early 20th century. The imposition of restrictive economic policies by Reza Shah in the 1930s led to the migration of most of the Huwala back to the Arabian Peninsula.
