Bhimsen Thapa (born August 1775 – 29 July 1839) was a Nepalese statesman who served as the Mukhtiyar (equivalent to prime minister) and de facto ruler of Nepal from 1806 to 1837. He is widely known as the first and the longest-serving prime minister of Nepal. He was inducted into the "National heroes of Nepal" by King Mahendra Bir Bikram Shah.

Born into an ordinary military family in the Gorkha Kingdom, Bhimsen first came close to the Crown Prince Rana Bahadur Shah at an early age in 1785. In 1798, he was recruited as a bodyguard for the King by his father. Thereafter, he rose to influence after helping the exiled ex-King Rana Bahadur Shah engineer his return to power in 1804. In gratitude, Rana Bahadur made Bhimsen a Kaji (equivalent to a minister) of the newly formed government. Rana Bahadur's assassination by his stepbrother Sher Bahadur Shah in 1806 led Bhimsen to initiate investigations into the context in which he ordered the death penalty for ninety-three people popularly known as the 1806 Bhandarkhal massacre, after which he claimed the title of Mukhtiyar (equivalent to prime minister) himself. The death of King Girvan Yuddha Bikram Shah in 1816 at the immature age of 17, with his heir, King Rajendra Bikram Shah being only 3 years old, along with the support from Queen Tripurasundari (the junior queen of Rana Bahadur Shah) allowed him to remain in power even after Nepal's defeat in the Anglo-Nepalese War. After the death of Queen Tripurasundari in 1832, the intrigues of the newly adult King Rajendra, the conspiracies and infightings with the British envoy Brian Houghton Hodgson, Senior Queen Samrajya Laxmi Devi and the rival courtiers (especially the Kala Pandes, who held Bhimsen Thapa responsible for the death of Damodar Pande in 1804) finally led to his imprisonment on false charges of the murder of an infant prince and ultimately his death by suicide in 1839.

Bhimsen Thapa is remembered for being the first Nepalese statesman to fully comprehend the British system of protectorate in India carried out by Lord Wellesley and his subsequent activities to keep British authorities at bay and prevent the Kingdom of Nepal from being a part of the British Empire through long and persistent anti-British politics during both wartime and peacetime. The territorial expanse of the Gurkha empire had reached its greatest extent from the Sutlej River in the west to the Teesta River in the east during his prime ministership. However, Nepal entered into a disastrous Anglo-Nepalese War with the partially British Empire-owned East India Company lasting from 1814 to 1816, which was concluded with the Treaty of Sugauli, by which Nepal lost almost one-third of its land. He is widely remembered for bringing about a large number of social, religious, economic, and administrative reforms, as well as the modernization of the Nepalese Army on the template of the French military forces. During his lifetime, he commissioned the construction of many temples and monuments including the highly famed Dharahara also known as Bhimsen Stambha ("Bhimsen Tower").

Widely considered one of the 19th century's most significant figures in Nepalese history, Bhimsen is seen as a patriotic, clever, and diplomatic statesman who played an important role in defending his country against then-widespread British colonial imperialism in South Asia. His foreign policy was largely motivated by rational national interest, national sustenance and nationalism. He is also well praised as a reformer and for his efficient systematization and management of the state administration, programmes and policies. However, he has been criticized for instigating an inhumane political massacre in his early political career, the elimination of his political rivals and the consolidation of political and military power within his family.

Early years

Bhimsen Thapa was born in August 1775 at Pipal Thok village of Gorkha district, to father Amar Singh Thapa (sanu) and mother Satyarupa Maya. His ancestors were members of Bagale Thapa clan from Jumla who migrated eastwards. His grandfather was Bir Bhadra Thapa, a courtier in Prithvi Narayan Shah's army. Bhimsen Thapa had four brothers — Nain Singh, Bakhtawar Singh, Amrit Singh, and Ranbir Singh. From his step-mother, he had two brothers — Ranbam and Ranzawar. While it is not certain when Bhimsen got married, he had three wives with whom he had one son, that died at an early age in 1796, and three daughters – Lalita Devi, Janak Kumari and Dirgha Kumari. Lack of a son caused him to adopt Sher Jung Thapa, son or grandson of his brother Nain Singh.

Not much detail is known about Bhimsen Thapa's early life. At the age of 11, Bhimsen came into contact with the Nepalese Royal Palace when his Bratabandha (sacred thread) ceremony was held together with the Crown Prince Rana Bahadur Shah in Gorkha in 1785. In 1798, his father took him to Kathmandu and enrolled him as a bodyguard to the king. In Kathmandu, Bhimsen took up residence at Thapathali, after which he lived in Bagh Durbar near Tundikhel after becoming a Kaji (equivalent to a minister).

Rise to power: 1798–1804

Royal household The premature death of Pratap Singh Shah (reigned 1775–77), the eldest son of Prithvi Narayan Shah, left a huge power vacuum that remained unfilled, seriously debilitating the emerging Nepalese state. Pratap Singh Shah's successor was his son, Rana Bahadur Shah (reigned 1777–99), aged two and one-half years at his accession. The acting regent until 1785 was Queen Rajendra Lakshmi, followed by Bahadur Shah (reigned 1785–94), the second son of Prithvi Narayan Shah. Court life was consumed by rivalry centered on alignments with these two regents rather than on issues of national administration, and it set a bad precedent for future competition among contending regents. The exigencies of Sino-Nepalese War in 1788–92 had forced Bahadur Shah to temporarily take a pro-British stance, which had led to a commercial treaty with the British in 1792.

Meanwhile, Rana Bahadur Shah's youth had been spent in pampered luxury. In 1794 Rana Bahadur came of age, and his first act was to re-constitute the government, with his uncle, Bahadur Shah, removed from all official position. In mid-1795, he became infatuated with a Maithili Brahman widow, Kantavati Jha, and married her on the oath of making their illegitimate half-caste son (as per the Hindu law of that time) the heir apparent, by excluding the legitimate heir from his previous marriage. By 1797, his relationship with his uncle, who was living a retired life, and who wanted to seek refuge in China on the pretext of meeting the new emperor, had deteriorated to the extent that he ordered his imprisonment on 19 February 1797 and his subsequent murder on 23 June 1797. Such acts earned Rana Bahadur notoriety both among courtiers and common people, especially among Brahmins.

That same year in 1797, Girvan Yuddha Bikram Shah was born and was hastily declared the crown prince. However, within a year of Girvan's birth, Kantavati contracted tuberculosis; and it was advised by physicians that she perform ascetic penances to cure herself. To make sure that Girvan succeeded to the throne while Kantavati was still alive, Rana Bahadur, aged just 23, abdicated in favor of their son on 23 March 1799, placing his first wife, Rajrajeshwori, as the regent. He joined his ailing wife, Kantavati, with his second wife, Subarnaprabha, in ascetic life and started living in Deopatan, donning saffron robes and titling himself Swami Nirgunanda or Nirvanananda. This move was also supported by all the courtiers who were discontented with his wanton and capricious behavior. It was around this time that both Bhimsen Thapa and his father Amar Singh Thapa (sanu) were promoted from Subedar to the rank of Sardar, and Bhimsen began to serve as the ex-King's chief bodyguard. Bhimsen received the position of personal secretary of King Rana Bahadur from the patronage of Mulkaji Kirtiman Singh Basnyat, since both his father and grandfather were in close military affiliations with Kaji Abhiman Singh Basnyat - the uncle of Kirtiman Singh. Meanwhile, Rana Bahadur's renunciation lasted only a few months. After the inevitable death of Kantavati, Rana Bahadur suffered a mental breakdown during which he lashed out by desecrating temples and cruelly punishing the attendant physicians and astrologers. He then renounced his ascetic life and attempted to re-assert his royal authority. This led to a direct conflict with almost all the courtiers who had pledged a holy oath of allegiance to the legitimate King Girvan; this conflict eventually led to the establishment of a dual government and to an imminent civil war, with Damodar Pande leading the military force against the dissenting ex-King and his group. Since most of the military officers had sided with the courtiers, Rana Bahadur realized that his authority could not be re-established; and he was forced to flee to the British-controlled city of Varanasi in May 1800.

Exile in Varanasi: 1800–1804

As Rana Bahadur Shah's bodyguard and advisor, Sardar Bhimsen Thapa also accompanied him to Varanasi. Rana Bahadur's retinue included his first wife, Raj Rajeshwari Devi, while his second wife, Subarna Prabha Devi, stayed back in Kathmandu to serve as the regent. Since Rana Bahadur was willing to do anything to regain his power and punish those who had forced him to exile, he served as a focal point of dissident factions in Varanasi. In November 1800, he first sought help from the British in exchange for which he was willing to concede a trading post in Kathmandu and grant them 37.5% of the tax revenue derived from the hills and 50% from the Terai. However, the British were in favor of working with the existing government in Nepal, rather than risk the uncertainties of restoring an exiled ex-King to power.

The Kathmandu Durbar was willing to appease the British and agreed to sign a commercial treaty so long as the wayward Rana Bahadur and his group were held in India under strict British surveillance. This arrangement was kept a secret from Rana Bahadur and his group; but when they eventually became aware of the strictures on their movement, and hence the treaty, they were incensed at the British as well as the proponents (Damodar Pande and his faction) of this treaty in Nepal. An intrigue was set in motion with the aim of splitting the unity of courtiers in Kathmandu Durbar and fomenting anti-British feelings. A flurry of letters was exchanged between the former king and individual courtiers in which he tried to set them up against Damodar Pande and tried to woo them by promises of high government positions, which they could hold for their entire life, and which could be inherited by their progeny. Baburam Acharya holds Bhimsen responsible for all these schemes, reasoning that Rana Bahadur did not have the mental capacity for such negotiations and intrigues. He contends that Bhimsen was responsible for negotiation with the British as well as responsible for writing letters in the name of the ex-King, while the ex-King was biding his time in debauchery. Similarly, historian Chittaranjan Nepali considered that in addition to the realization of the motive of Nepali Bharadars to detain Rana Bahadur's retinue in Banaras, Bhimsen also had fully realized the real meaning of the system of protectorates adopted by the East India Company Government.
