The Great French Revolution brought the world not only a picture of the people's struggle against the hated regime, but also a number of heroes and personalities, for whom it became a springboard to fame. The Grande Armée became a kind of "seedbed" of these nascent heroes, who fought valiantly for their ideals. If they did, they rose rapidly through the military hierarchy, and with the gradual increase in their wealth, their ideals were later replaced by a desire for power. Some began to make their own plans, pursue their goals, and no longer serve in the military with as zeal as during the revolution. Jean-Baptiste Jules Bernadotte was a very controversial figure from Napoleon's marshals.
After gaining the status of a man from the Bonaparte family, his self-confidence increased. Despite hesitations in the Grand Army and Napoleon's favor, the Swedish authorities led him to the royal crown, and later turned his back on the man who had enabled him to further his career.
