Lakhan Thapa Magar (1835–1877) was a Nepali revolutionary whom Nepal government has declared "The First Martyr of Nepal" He was the first revolutionary leader who, for the first time in history, resisted the government in Nepal namely: the rule of the Rana dynasty 1846 - 1950. He rebelled against the tyranny of Jang Bahadur Rana. He was supported by his close friend Jay Singh Chumi Magar. Jaya Singh Chumi was his minister. He propagandized his political ideology to destroy the Jung Bahadur Rana regime, to form a free state and army.
The mysterious killing of General Gagan Singh Khawas, followed the Kot Massacre of September 14, 1846 that catapulted the Ranas into power to last for 104 years. The reigning queen wanted to know the murderer of General Gagan Singh Khawas. General Abhiman Singh Basnyat, who was the first General or Commander-in-Chief of Nepal Army had known who the killer was. Jung Bahadur Rana, therefore shot him at his chest and the dying General Abhiman Singh Rana Magar, shouted, "Junge was the killer of Gagan Singh"("गगन सिंहको हत्त्यारा जंगे नै हो"). It is understandable that Junga Bahadur Rana had to finish all nobles in the royal house and other in the country, that included ethnic leaders like Lakhan Thapa Magar to secure his position. His iron-fisted rule scared people in the country.
Lakhan Thapa Magar, a man of great courage could not tolerate it. He organized some youths that included ex-army men also from his area and began to protest against the government. Later Jung Bahadur Rana knew it and sent his troops to Gorkha. The troops captured and hanged him to death with his friend Ajay Singh Chumi Magar. Some historians write the government captured other 50 youths also and hanged all of them along with Lakhan Thapa Magar. But one of the descendants of Jung Bahadur Rana has otherwise dismissed Magar's martyrdom. But all renowned historians of Nepal have attested that Lakhan Thapa Magar was hanged to death. Junga Bahadur Rana had risen to power with brutal massacre of the nobles of Nepal Durbar. The Kot Massacre was the beginning of 'black days' of Nepalese history. Junga Bahadur Rana was a ruthless ruler. It can't be even imagined such a cruel ruler, who had risen to power through conspiracy and bloodbath would have left anyone unharmed, who had opposed him so vigorously for the first time.
Another historian and then Director General of Nepal Government's Department of Archaeology has written that Jung Bahadur Rana's tyrannic rule had reached its optimum limit; people had suffered beyond imagination. Therefore, Thapa Magar began to organize people against the government. Taking some ex-army-men into his organization, Thapa Magar began a rebellion from Bunkot, Kahule Bhangar in Gorkha. People overwhelmingly supported Thapa Magar's movement. His organization grew leaps and bounds. In the meantime, government secret service agents reported what Thapa Magar was doing against the Rana regime. That was a 'first ever political movement against any Nepalese government' which was totally corrupt and tyrannic, extremely unpopular and fundamentally against the public interest. Jung Bahadur Rana thought, he must stop the rebellion or else he had no future. So, Jung Bahadur sent his troops to crush the rebellion. While Lakhan Thapa Magar and his seven friends were in a secret meeting, the government army got into there and captured all of them. The troops searched and found 60 guns and other arms and ammunition also. Thapa Magar and other captives, arms and ammunition were brought into Kathmandu.
