The Baloch are the majority ethnic inhabitants of the region of Balochistan in Iran. They speak Rakhshani Balochi, an Iranian language. They mainly inhabit mountainous terrains, which have allowed them to maintain a distinct cultural identity and resist domination by neighbouring rulers. The Baloch are predominantly Muslim, with most belonging to the Hanafi school of Sunni Islam, but there are also a few number of Shia in Balochistan. Approximately 25 percent of the Baloch population live in Iran: media reports indicate there are 1.5 million Baloch in Iran. The utter vast majority of the Baloch population reside in Pakistan, and a significant number i.e. 600,000 reside in southern Afghanistan. They are also spread in other countries of the world, such as the Persian Gulf states and Europe.
