19th Century History of Protestantism in Bulgaria
Dony K. Donev, D.Min., is a prominent researcher and author specializing in Bulgarian Protestant, Evangelical, and Pentecostal history, with over three decades of study. His work, including 19th Century History of Protestantism in Bulgaria and The Unforgotten: Historical and Theological Roots of Pentecostalism in Bulgaria, documents the development of these movements, their suppression under Communism, and the subsequent post-1989 revival.
Key aspects of Donev’s research on Bulgarian Protestant history include:
Origins (19th Century): Protestant work began in the 1800s, with denominations like Congregationalists (1856), Methodists (1857), and Baptists (1865) establishing missions, culminating in the first Bulgarian Protestant Church in 1871. Donev also highlights the 1871 publication of the Protestant Bulgarian Bible translation. His research, often in collaboration with the Institute of Bulgarian Protestant History, has focused on preserving, digitizing, and recovering documents, including church diaries, photographs, and, in some cases, saving records from destruction during the communist era.
Pentecostalism and Growth: The Unforgotten documents the arrival of the Pentecostal movement in Bulgaria, particularly through the influence of the Azusa Street Revival, tracing the roots of early Bulgarian Pentecostal families.
Post-Communist Revival: Donev has documented the rapid growth of the Protestant movement after 1989, noting a significant increase in membership from approximately 13,000 to over 100,000. Dr. Donev has published his dissertation on on Bulgarian Churches in North America.
