Arabs in India are people with Arab origins who have over a long period of time, settled in the Indian subcontinent. There have been extensive trade and cultural links between India and the Arab world spanning several millennia. The west coast region of India, especially Malabar and Konkan coasts were active trading hubs, where Arab merchants frequently used to visit on their way to Sri Lanka and South East Asia. Over a span of several centuries, migrants from different Arabian nations immigrated to various regions and kingdoms of the Indian subcontinent as merchants, missionaries and through intermarriages. Communities The earliest immigrants from the Arab world arrived as merchants to the Malabar coastal region of South West India, today consisting of the state of Kerala. Many of these Arab merchants intermarried with local women. Concentrations of these mixed-race descendants of Arab merchants can be found especially in the Kozhikode and Malappuram districts of Kerala. There also have been historic and close links between the Orthodox churches of South-West India and the Christian Arab orthodox churches in the middle east for several centuries, especially among the Orthodox Christians in India and Syria, which they maintain until this day and many of the Christians from these communities have claimed their ancestors are Arabs and the DNA results support this claim with Haplogroup G-M201 and Haplogroup J-M304 being prominent. Descendants of Arabs also live in the villages of Variav and Rander in Gujarat. In Hyderabad, Chaush are an Arab community of Hadhrami descent whose ancestors were recruited as soldiers by Nizam of Hyderabad. In coastal Karnataka, a group of Persian speaking Sunni Muslims from Iraq having Assadi surname arrived in Mangalore during the reign of Tipu Sultan. They claim their ancestry from Banu Assad. These population migrations may have been favoured by both the Nizam of Hyderabad and Tipu Sultan of Mysore because both had their ancestral linkages to these populations. The Asaf Jahi Dynasty claimed Arab ancestry from Asir Province and Tipu Sultan from the Bani Hashim of Hijaz Province in Arabia. Many Arabs having Adnani ancestry such as Quraishi, Ansari tribes and other descendants of the Sahaba were employed by the Princely States in their military as they were found efficient during warfare in Gujarat and Karnataka. In Kerala, Syed Thangals of Hadhrami descent settled around the 17th century as missionaries to propagate Islam. There are also Shia Sayyids in the Northern
