And Nepal was never colonized by any country but, Nepal remained a protectorate of the East India Company and subsequently of the British Empire from 1816 to 1923, after when Nepal was rewarded for providing much help in WW1 to the Raj. By protectorate it means, that the Foreign Policy and the Defense was handled by the English, just like the Bhutan of current days by India. However, Bhutan has leaped a little forward by defying the treaty at times?? So, Nepal is not completely sovereign in its history as Thaland (Siam) is. During the reign of jung Bahadur, to revenge the tributaries, nepal invaded Tibet and won the battle and started receiving tribute from Tibet, but after 3 years, the tribute stopped. Out of anger, Jung invaded tibet, but his time, the chinese army helped them to defeat Nepal, adn the chinese armies were actually pretty close to Kahtmandu. close enough to negotiate at Thapathali - thus thapathali sandhi at the resident of Jung - present day Nepal Rastra Bank. Also, in the first attempt, jung's army reached the outskirts of Lhasha, nearly taking over the Tibet.
