Bhimsen Thapa of Bagale Thapa clan rose to prominence after the assassination of King Rana Bahadur Shah of Nepal by King's step-brother in 1805 AD.
After the event, an investigation was run by Bharadars (Ministers) which caused massacre of 55 senior officers at Bhandarkhal garden by Thapa Kaji (ministers) group making them as most dominant faction in Nepalese politics.

.It would be true to say that History has been written by the Brahamin which underestimated and burried the history of all the other beautiful community of Nepal.

After Bhimsen rose to power, member of another Thapa family, Bada (senior) Kaji Amar Singh Thapa and his family were added to make Thapa Khalak dynasty stronger.
Large number of Thapa leaders took part in Anglo-Nepalese War in 1814-16 AD.

Later Panchayat government of Nepal that began in 1961 AD saw large number of Thapas in the cabinet.
