Analysis and Evaluation of the History of Protestantism in Bulgaria

Bulgaria adopted Eastern Orthodox Christianity as its state religion in 865 AD, shaping its national identity. Protestantism was introduced to Bulgaria in the early 19th century, during Ottoman rule, by American missionaries. Following Bulgaria’s independence in 1878, Protestantism expanded but faced suppression during the Communist period (1946 – 1989). The democratic transition facilitated its growth but also brought new challenges. This paper examines the introduction, historical development, demographic changes, and geographic distribution of Protestantism in Bulgaria; analyzes its contemporary difficulties; and proposes future directions for its development in the country.
