The Rana oligarchyराणा शासन
104 years of hereditary prime ministers; kings reduced to figureheads
After the Kot massacre of 14 September 1846, Jung Bahadur Rana made the premiership the hereditary property of his family. For 104 years the Ranas ruled as de-facto monarchs — isolationist, autocratic, but also the era of sati's abolition (1920), slavery's end (1924–26) and Britain's recognition of full Nepali sovereignty (1923).

What happened
On the night of 14 September 1846, amid the crisis that followed the murder of general Gagan Singh, Jung Bahadur Rana's men cut down some forty nobles assembled in the palace armoury (the Kot). Queen Rajya Lakshmi named Jung Bahadur prime minister the next day; within months he had made the office hereditary in his family and reduced the Shah kings to ceremonial seclusion.
Rana rule was orderly, extractive and deliberately isolated — Nepal stayed closed to most foreigners. Yet it produced milestones: Jung Bahadur's 1850 journey to Britain (the first by a South Asian head of government), the Muluki Ain legal code of 1854, Chandra Shumsher's abolition of sati on 8 July 1920 and of slavery (proclaimed 28 November 1924, completed 1926), and the Nepal–Britain Treaty of 21 December 1923, which formally recognised Nepal's full independence — superseding Sugauli.
Padma Shumsher's Government of Nepal Act of 1948 — the country's first written constitution — promised limited representation, but his successor shelved it. By then exiled democrats (the Nepali Congress), a restive king (Tribhuvan) and post-colonial India were aligned against the regime. The armed revolution of 1950–51 and the Delhi Compromise of February 1951 ended Rana autocracy after 104 years.
