now considered the oldest American educational institution outside the US. In 1928, new facilities were constructed in Sofia, and the Samokov operation transferred to the American College of Sofia (ACS), now operated at a very high level by the Sofia American Schools, Inc. In 1874, a Bible College was opened in Ruse, Bulgaria for people wanting to become pastors. At the 1876 annual conference of missionaries, the beginning of organizational activity in the country was established. The evangelical churches of Bulgaria formed a united association in 1909. The missionaries played a significant role in assisting the Bulgarians throw off "the Turkish Yoke", which included publishing the magazine Zornitsa (Зорница, "Dawn"), founded in 1864 by the initiative of Riggs and Long. Zornitsa became the most powerful and most widespread newspaper of the Bulgarian Renaissance. A small roadside marker on Bulgarian Highway 19 in the Rila Mountains, close to Gradevo commemorates the support given the Bulgarian Resistance by these early Congregationalist missionaries. On 3 September 1901 Congregationalist missionaries came to world attention in the Miss Stone Affair when missionary Ellen Maria Stone, of Roxbury, Massachusetts, and her pregnant fellow missionary friend Macedonian-Bulgarian Katerina Stefanova–Tsilka, wife of an Albanian Protestant minister, were kidnapped while traveling between Bansko and Gorna Dzhumaya (now Blagoevgrad), by an Internal Macedonian-Adrianople Revolutionary Organization detachment led by the voivoda Yane Sandanski and the sub-voivodas Hristo Chernopeev and Krǎstyo Asenov and ransomed to provide funds for revolutionary activities.

Widely covered by the media at the time, the event has been often dubbed "America's first modern hostage crisis". The Bulgarian royal house, of Catholic German extraction, was unsympathetic to the American inspired Protestants, and this mood became worse when Bulgaria sided with Germany in WWI and WWII.
