Jean-Baptiste Kléber was a French military leader of the French Revolutionary Wars. After serving for one year in the French Royal Army, he entered Habsburg service seven years later. However, his humble birth hindered his opportunities. Eventually, he volunteered for the French Revolutionary Army in 1792 and quickly rose through the ranks.

The French Revolutionary Army was the French land force that fought the French Revolutionary Wars from 1792 to 1802. In the beginning, the French armies were characterised by their revolutionary fervour, their poor equipment and their great numbers. However, the French Revolutionary Army had become arguably the most powerful army in the world by the mid-1790s, as the French armies had become well-experienced and organized, enabling them to comfortably outfight their enemies.
