Exasperated, the XIX-th century France had decided to change everything.

Please note that despite the rather inept leadership offered by the last three kings, France was the dominant European power of the moment. Economically, demographically and militarily.
Exasperated people tend to make rather poor decisions.

Napoleon Bonaparte was permitted to rise to power. To absolute power…
He yielded that power in such a way that he had angered most of his neighbors. Most of France’s neighbors… Which had banded together and defeated him. Twice.

Which was a premiere.
A bully put down by an alliance… A bunch of autocrats put off by another who decided they had enough.

The same template was used against Germany’s dictators. Both Wilhelm II and Hitler had been put down by coalitions. By people fed up with their antics.
A somewhat similar thing happened during the Cold War. A bullying regime, the Soviets, was kept in check by an informal ‘coalition of the willing’. ‘Informal’ in the sense that NATO was only the ‘tip of the iceberg. In reality, the Soviet Union had been defeated by the ‘free world’ working in concert.

Nowadays, ‘living in interesting times’, we witness another coalition taking shape.
Three authoritarian leaders ‘pushed together’ by a fourth one… By the antics perpetrated by a guy pretending to uphold freedom. Absolute freedom…!
