Great Britain won a war against Afghanistan in 1919, using native Indians as foot soldiers. How did most native Indians feel about Britain after that war ended? They wanted the British government to open its borders and allow greater migration of Indian citizens into Great Britain.
They were pleased that they were ruled by the most powerful country in the world--a ruler that would protect them from surrounding rivals.
They began to question their treatment by the British, who used them as soldiers but continued to disrespect and mistreat them.
They sought immediate termination of all control by the British government because they were discouraged by the way Afghans were treated.
