Talom Rukbo (1937–2004) is widely revered as the father of the Donyi-Polo movement, a spiritual and cultural revival that seeks to preserve and promote the indigenous faith of the tribes of Arunachal Pradesh. Donyi-Polo, meaning "Sun and Moon," is the traditional animistic religion practiced by many tribal communities in the region. Rukbo’s efforts were pivotal in organizing and codifying this ancient belief system at a time when modernization and external influences threatened to erode indigenous identities. A scholar, philosopher, and social reformer, Talom Rukbo worked tirelessly to promote tribal pride, cultural preservation, and environmental harmony through Donyi-Polo. He established prayer houses called “Ranghars” and encouraged the younger generation to embrace their ancestral traditions while engaging with the modern world. Talom Rukbo’s legacy continues to inspire cultural and religious movements across the Northeast, with many communities still celebrating Donyi-Polo festivals and rituals that honor nature and ancestral spirits. He remains a symbol of indigenous pride and cultural renaissance in Arunachal Pradesh.
