American "Revolution"? Fought for by aristocrats and lead to little major political change. Boston "Massacre"? Five people dead, less than shootings today. British "tyranny" upon elite American colonists? A tax exclusively on tea, not literal genocide like they did to India and others
Somerset v Stewart is probably what you're talking about.
