Jong Batak Bond

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.

[8][9][10][11][12] Led by Djabangoen Harahap, Ferdinand Lumban Tobing, and Sanusi Pane, this new group hoped to discuss, study, and modernize Batak culture, which at that time had a very low status in Indies society.

From 30 April to 2 May 1926 members of Jong Batak participated in the First Indonesian Youth Congress in Weltevreden led by Mohammad Tabrani.

Although the organization was short-lived, many of the members and leaders of Jong Batak went on to become influential in the Indonesian nationalist movement and in politics after Indonesia gained its independence in the 1940s.

Todung Sutan Gunung Mulia, Sjarifuddin's cousin, had been a Volksraad member during colonial times and was Minister of Education and Culture from 1945–6 and was also involved in the founding of the Indonesian Christian Party.
