In the Monty Python film Life of Brian there is a a scene known to Python fans as the ” What have the Romans ever done for us” . This involved John Cleese asking repeatedly “What have the Romans ever done for us ?” with various members of the cast coming up with things such as Roman roads, clean drinking water, education, medicine. All of this was done for comic effect but it had a serious message because the British Empire like the Roman one brought a great number of useful things to the subcontinent .Hence we can play What did the British ever do for us?, viz
What did the British do for India (and the rest of the subcontinent) ?
Created an entity called India from an amalgam of warring states
Stamped out many vile practices such as thugee and Sati.
Gave India the largest railway system in the world
Gave India modern roads
Gave India introduction to western Science
Gave India a modern education system
Gave India a modern system of law
Gave India a modern police force
Gave India a modern civil service
Gave India a modern Army
Gave India a modern navy
Gave India an air force
Gave India a modern civil service
Gave India an inside track to modern medicine
Gave India an inside track to industrialisation
Rescued much of the subcontinent’s history
Stopped serious Muslim/Hindu massacres of one another
Gave India a form of representative government
Built New Delhi
Introduced cricket to the subcontinent
The what did the British do for us? can be employed when judging the British Empire generally .
British official colonial policy from around 1900 was (1) to eventually raise the culture of the indigenous peoples in those colonies to a state where they could rule themselves .and (2) until those people were fit to rule themselves to act as guardians to those people.
As to the specific things the British brought to the colonies in general, those I listed for India were brought in part to to the colonies widely the most widespread being schools and universities, medical facilities and the idea of representative government.
More generally the exercise can be employed for any country. Why not have a go?
