Bahraini people are ethnically diverse. There are at least 8–9 different ethnic groups of Bahraini citizens. Shia Bahraini citizens are divided into two main ethnic groups: Bahrani and Ajam. Most Shia Bahrainis are ethnic Baharna, the Baharna being descendants of the original pre-Islamic inhabitants of Bahrain. The Baharna speak a variety of Arabic known as Bahrani Arabic. The Ajam are ethnic Persian Shias. Bahraini Persians maintain a distinct culture and language, but have long since assimilated into Bahraini culture; they tend to identify themselves as Persian Bahrainis rather than Iranians.
