An alliance had already been concluded between the Confederation and the French king under Louis XIV in 1663, which primarily focussed on military aspects. Due to internal disputes between the cantons, this alliance was not renewed in 1715. It was not until Louis XVI attempted to reach an agreement again, which was achieved in 1777. The renewal was celebrated on 25 August in Solothurn, the official residence of the French ambassador, to which this medal refers.
