In the Declaration of the Independence, the word usurpation is used to imply “the unlawful suppression or denial of citizens' rights.” It might have also been used to imply oppression, exploitation, injustice, confiscation, torment, persecution, coercion, intimidation, etc. The authors of the Declaration chose to repeat the word to emphasize the point that the impositions of the King on the colonists were both abusive and unlawful.
