Teen Maharaja, Dev Shamsher Jang Bahadur Rana (July 17, 1862 - February 20, 1914) was Prime Minister of Nepal for only 144 days in 1901.
He was the fourth of 17 sons born to the Chief of the Army Dhir Shamsher Rana (a younger brother of Jang Bahadur) and Rani Nanda Kumari, niece of Bhimsen Thapa and Mathbar Singh Thapa who were both prime ministers of Nepal.
His father and brothers had difficulties in maintaining a huge family. The Shamshers were poorer than the Jang and other cousins, so to ease the burden on Dhir Shamsher, Dev Shamsher was adopted at a very young age by his father's childless elder brother, General Krishna Bahadur Kunwar Ranaji and was raised by him and his wife.
As the adopted child of General Ranaji, who was a governor of Palpa, Dev Shamsher had a lavish upbringing compared to his natural brothers. The only occasions that he met his own siblings were during festivities and family gatherings. He was closer to the sons of Jang Bahadur and spent the majority of his time in their palace, Thapathali Durbar. He inherited the entire wealth of his uncle as well as a share of his father's wealth. Since he was much richer than his brothers they became envious.
