100 Francs

The Société Générale pour Favoriser l'Industrie Nationale was a Belgian joint-stock bank chartered in 1822 under Dutch rule — essentially a state-backed institution designed to channel capital into the newly industrializing southern provinces. By the time this note was issued in 1837, Belgium had been independent for seven years, and the Société Générale had survived the political rupture largely intact, retaining its dominant position in the Belgian financial system despite having initially backed the Orangist cause during the 1830 revolution.

A 100-franc denomination in this period was a substantial instrument, moving between merchants and industrial financiers rather than through ordinary retail exchange.
