What began with the great tea robbery from China by Robert Fortune, a Scottish botanist, plant hunter, and adventurer, eventually resulted in the displacement of indigenous Lepchas from former Dorje-Ling and subsequently the migration and subjugation of Nepalis. These migrants were critical in the development of technical wonders like as the Toy Train, roadways on Darjeeling's steep hills, and the cutting out of plantations on hills formerly held by old forests. All of this was done to meet the demand for tea in London.
