<![CDATA[The people joyfully welcomed the proclamation of independence that echoed through Tanah Karo. However, the independence was tested by the arrival of Dutch colonialists who sought to re-establish themselves. This study aims to explain the emergence of the nationalism movement in Tanah Karo and the development of the idea of nationalism during the revolutionary period that filled the movement. This research uses the historical method, which consists of heuristics, source criticism, interpretation and historiography. The sources used are archival documents, interviews, contemporary newspapers, and other sources relevant to this study. The results showed that the emergence of the nationalism movement was brought by Karo intellectuals who were members of the PNI. They came from economically well-established families and studied in Medan. The youth from Karo played an essential role in building the spirit of nationalism as a driving force in the people's struggle against the Dutch colonialists who sought to regain power. The transmission of the idea of nationalism was brought to Tanah Karo through media in the form of writings, speeches, training, learning and other things that aroused the passion of the people's resistance. Meanwhile, in the dynamics of the movement carried out through the spread of ideas of nationalism, there was a conflict between the ranks of the struggle, which could then be reduced by strategizing the struggle because there was a fear that the enemy would use the atmosphere.Proklamasi kemerdekaan menggema hingga ke Tanah Karo disambut rakyat dengan gembira namun sebagai upaya mempertahankan kemerdekaan dengan kedatangan kolonial Belanda yang ingin berkuasa.
