Huwala also collectively referred to as Bani Huwala, are Arabian Iranians 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 follow Sunni Islam, like most Peninsular Arabs, and as opposed to the majority of Persians, who are Twelver Shia. 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 rest of the Huwala back to the Arabian Peninsula.
