The cockades of the three Nassau duchies up to 1806 were monochrome black. Presumably – as in other German states – coloured cockades were introduced during or after the Napoléonic era, which were designed as a golden-blue national (oval cockade) for the only one Duchy of Nassau, which existed from 1815.
