Flag of King Sisingamangaraja

The Flag of King Sisingamangaraja is the standard or banner used by the Sisingamangaraja dynasty during their long reign over Bakkara and over the territories around Lake Toba. The flag can be found in places such as the Tomb of Sisingamangaraja in Balige and also in the Sisingamangaraja Memorial in Tarutung, however the flags in these places are mere replicas, as the original banner was taken by Hans Christoffel, a Dutch captain sent to kill Sisingamangaraja XII. Today the original banner can be found in the Aan de Stroom Museum, Belgium.
