This thesis examines the reform ideas and efforts of Daud Shah, a Muslim socio-religious reformer in the Madras Presidency during the twentieth century. Shah published a journal, Dar ul-Islam (World of Islam), which he used as a medium to propagate his ideas and advocate reforms among Muslims. Socio-religious reform efforts among Muslims in the Madras Presidency have received very limited scholarly attention. But the purpose of this thesis goes beyond merely focusing on a neglected area of scholarship. Shah belonged to a small class of Western-educated Muslim professionals. This thesis will demonstrate how Shah’s reform efforts differed from those advocated by the aristocracy and the merchant elite. This thesis will analyze the relationship between Shah and the national-level reform movements among Muslims. Shah’s reform and fundraising efforts also reveal the close links between Muslims in Tamil Nadu and Southeast Asia. Finally, the thesis will show the influence of print technology on reform movements among Muslims. / text
