Bahraini people are ethnically diverse. Shia Bahrainis are divided into two main ethnic groups: Baharna and Ajam. The Shia Bahrainis are Baharna (Arab), and the Ajam are Persian Shias. Shia Persians form large communities in Manama and Muharraq. A small minority of Shia Bahrainis are ethnic Hasawis from Al-Hasa.
