In 1857, when the Great Indian Rebellion had started against the rule of the British, many Muslims of Manglaur joined the rebellion. They attacked many British Army outposts in and around the town of Manglaur. The Muslims in this region played a vital role during the rebellion fighting against British rule. After the rebellion was over, a Madrassa named Jamiya Arbiya Al Muslimeen was established in Manglaur. During British rule until 1947, it was an important learning and education centre for Muslims all over British India. After the Partition of India in 1947, the town became a part of Uttarakhand state in India and some Muslims fled to Delhi to board the refugee trains heading to the newly-created nation of Pakistan but the majority of Muslims surprisingly stayed in India. Today, the Muslims are a well established community in this town and the town is also the only majority Muslim region in the state of Uttarakhand.
