[8] After being installed as a constitutional monarch, King Louis Philippe I required a way to keep dangerous elements of his regular army busy, regardless of whether they were French or foreign nationals.
There were also concerns about certain soldiers being foreign insurrectionists or volunteer fighters who had joined the army in the hope of continuing the 1789 Revolution.
