This study examines the life and multifaceted legacy of Veled Çelebi İzbudak (1869–1953)—a Mevlevi sheikh, Ottoman bureaucrat, and key figure in Turkish linguistic reform. Positioned at the intersection of tradition and shifting sociopolitical dynamics, İzbudak’s career exemplifies how Sufi intellectuals actively engaged with and negotiated the ideological and administrative transformations from the late Ottoman empire to the early Turkish republic. By situating İzbudak within the broader historical transformations of his era, the article highlights his engagement with significant reforms, such as the closure of Sufi lodges (1925) and the language reform (1928), revealing his dual role as a preserver of religious heritage and a proponent of modern state-building initiatives. Through an analysis of his memoirs, writings, and official correspondence, this research uncovers how İzbudak reconciled his Sufi commitments with the nationalist ideals of the republic, emphasising his advocacy for Turkish linguistic preservation as a bridge between Ottoman Sufi legacies and the emerging cultural identity of modern Turkiye. Challenging the reductive portrayal of Sufi figures as passive in the face of reform, the study argues that İzbudak exemplifies the nuanced agency of Sufi bureaucrats, offering a deeper understanding of their contributions to cultural, linguistic, and political transformations during a pivotal period in Turkish history.
