فيلكا
The majority of Kuwaitis from Failaka Island are of Iranian ancestry. They originally migrated to Failaka from the Iranian coast, mainly Kharg Island and Bandar Lengeh. These people are commonly known as the Huwala in the GCC states. They are predominantly Sunni Muslims and speak Arabic fluently, although prior to the discovery of oil they also spoke Persian fluently. The most important Huwala settlement in Failaka Island pertained to 40 families who migrated from the Iranian island Kharg to Failaka in the years 1841–1842. The most recent settlement occurred in the early 1930s after the imposition of the unveiling law by Reza Shah. A minority of Failaka Island's Kuwaiti families are Shia Persians, they were noted as having their own hussainiyas and the older generations were frequent Arabic speakers, unlike the Kuwaiti Shia of Persian origin in mainland Kuwait City at the time.
