Don't get me wrong, but please tell me who are those people you call 'notable missionary'? How much do you know about them? Say, father Giuseppe who wrote that piece on Asiatic Researches about Kirtipur assault. Tell me what else you know about him to make him so notable except that what he wrote perhaps sounds concordant to those ears that want to feel they are victimized?

In reality, if you look at the geopolitics of that time, the Italian and Spanish missionaries went around the world to convert. In America (South/North), they were instrumental in leading emperialists and destroying local culture. In Kathmandu too, you can find evidence of such destruction or attempted destruction of local culture by missionaries. Missionaries like Giuseppe were not happy that they were kicked out by Prithwi Narayan Shah after he conquered Kathmandu. They just wrote bad things about  him and campaigned against him from their refuge in Bettiah. Some of what they wrote were perhaps true--but mostly they were writing with extreme hatred and malice towards Prithwi. It is like relying on America government's account of Iran (once kicked out of the gas deals and other stuffs they malign them)!

In any case, let me know what professional integrity and conduct of those people led you to brand them as notable men. They were just agent of conversion. They first went to Tibet to convert in seventeenth century, but finding Kathmandu nearer, and finding Tibetans more spiritual than their liking, they came to Kathmandu.
