Thangal, in Malayalam, is an honorific Muslim title used in Malabar region of Kerala, India. It is equivalent to the Arabic Sayyid (سيد), which is given to males accepted as descendants of the Islamic prophet Muhammad through his grandsons, Hasan ibn Ali and Husayn ibn Ali, who were the sons of his daughter Fatima Zahra and son-in-law Ali ibn Abi Talib.
Thangals are descended from the Sayyid family, which emigrated from the historic city of Tarim, Hadramawt Province, Yemen during the 16th and 17th century in order to propagate Islam. They selected coastal areas like Kannur, Koyilandy, Kappad, Mampuram, Ponani and Kochi to settle for the sake of convenience of their transportation. The Royal family of Arakkal had Thangal origins, but the last ruler, Ali Raja Mariumma Beevi Thangal handed over the power to the Indian government.
