Which of the French rulers proclaimed himself emperor?

Usually, the right to the throne was inherited in monarchical states. But as a result of the upheavals of the 18-19 centuries in France, the system of succession to the throne changed. Napoleon Bonaparte after the revolution became the high consul, and then the only ruler. He strengthened his sole power by the fact that in 1804 he appointed himself Emperor of France. This title was approved by the majority of those close to him, since at this time Napoleon was making progress in military affairs. He also managed to bring the country out of the crisis.
