Jong Batak Bond
Jong Batak Bond (Dutch for "young Batak association"), sometimes simply called Jong Batak, was a short-lived but influential Batak intellectual organization founded in Batavia, Dutch East Indies (today Jakarta) in December 1925. Like Budi Utomo, Jong Java and other such organizations, its members consisted of native Indonesian students in Dutch-language schools interested in advancing their ethnic group and Indonesian nationalism at the same time. Notable members of the group include Amir Sjarifuddin Harahap, Todung Sutan Gunung Mulia Harahap, Sanusi Pane, Saleh Said Harahap and Arifin Harahap.
Members of the organization represented by Sjarifuddin Harahap participated in the 1928 Youth Pledge which is considered to be one of the major events in the development of the Indonesian nationalist movement. By 1930 Jong Batak, and most of the other "ethnic" associations, had merged into the pan-Indonesian group founded by Sukarno, Indonesia Muda.
