one day, a spanish explorer came to india, his name was Vasco de Gama.
seeing the rich culture and spices, he immeadietly went to queen elizabeth and told her about the culture and heritage of india.
she immeadietly ordered 200 men to form the east india company, a trading company, who would set up godowns in india, starting from Dehradun.
they soon got control of india, and forced farmers to grow an extremely rare crop, indigo, which is a blue dye, for a very cheap price. like this, the people in india became poorer and poorer, while the british became rich.
hope this was what you were looking for!
