The Bulgarian Political and Ethnical Presence in Obluchitsa-Isakcha from the End of 12thto the End of 17th Centuries

During the 13th–15th centuries Obluchitsa-Isakcha was ruled by various states. It finaly fell under Ottoman rule in 1419/1420. A number of autors claim that the Danubian town was located on Bulgarian lands. The name “Obluchitsa” also testifies to his Bulgarian affiliation. It was preserved and used alongside the name “Isakcha” for a long time, wich is evident in many historical sources. In 1462 Bulgarians were the predominant Christian population inhabiting Obluchitsa-Isakcha. Although foreign invasions had a negative impact on the town's population, the Bulgarian ethnical presence remained strong among its diverse population in the 16th–17th centuries.
