How long did absolutism last?

First of all, that's a very vague question to answer as there has been accounts of the concept, absolutism, all through history, but there were three centuries that scholars narrow their focus and study to, and that is, The Age of Absolutism. The Age of Absolutism is historically considered to be between the 1500-1800s, the height being during the European Renaissance, exemplified by Louis XIV (the most flamboyant, yet progressively artistic despot, arguably) and the low point of absolute authority by a single individual was, in my opinion, when we defeated the British during the Revolutionary War and opened up the eyes of the commoners, who were harvesting a deep resentment of British Absolutism on both sides. Americans wanted to be free, and the British citizens were against the war due to a plethora of reasons, spearheaded by increased senseless taxes to support a more senseless war, as well as an increasingly maddening King, which is never a good thing. Obviously there have been other times in history prior to 1500 where absolutism was the ruling force, but those three centuries are considered the zenith of absolutism. Ultimately, absolutism fell out of favor and lost support amidst the French Revolution, which promoted ideas of sovereignty which became extremely popular becoming known as....well...., Popular Sovereignty.
