Britain recognized Nepal as an independent nation only in 1923 after the participation of soldier's from Nepal in the Great War. Obviously, certain historic facts were kept off our textbooks. For example: King Prithivi Narayana punishing citizens by cutting off their nose or ears after the conquest of Kirtipur. It has been mentioned in Kirtchpatrik's Nepal quoting a christian missionary who visited back then. To a different question of where the Shah dynasty came from: it has been mentioned on www.4dw.net/royalark/Nepal/nepal.htm that the ancestors were from Chitor dynasty of Udaipur, presently in India. I haven't done my own research on that yet. More lights would be appreciated.
