We're not Punjabi, we were part of Punjab for only 108 years

I thought every haryanvi knew that we became part of Punjab in 1858 because we revolted against Britishers in 1857 rebellion and Punjabi kings sided with Britishers so Britishers merged haryana with punjab to to control it easily with the help of loyalists BUT I guess I was wrong because I've seen some haryanvis saying that they think they're ethnically punjabi because we were part of Punjab for some time
