[5] HKBP also has several churches abroad, such as in Singapore, Malaysia, and in California, New York, and Colorado in the United States.[6] The first Protestant missionaries who tried to reach the Batak highlands of inner Northern Sumatra were English and American Baptist preachers in the 1820s and 1830s, but without any success.In 1889, the RMG sent out Hester Needham who started the work with girls and women and later established the first Batak deaconess.In the last quarter of the 19th century, further missionaries of the RMG were sent out to the other Batak tribes (Angkola, Dairi, Simalungun, Karo, and Pakpak).In 1977, Sekolah Tinggi Theologia (STT or "Theological Seminary") HKBP split from Nommensen University.
