The design dates to 1803, based on the flag used in the Vaudois insurrection against Bernese rule in the 1790s, which was green and inscribed with Liberté, Egalité in white lettering. From this, the white and green became the "revolutionary" colours of cantons newly created from former subject territories of the confederacy, also used in the flags of the cantons of St. Gallen and Thurgau, and a green flag was also briefly used by Aargau.
The lettering in the Vaudois flag was in black or in green during 1803–1819, the gold was introduced with the military flag as Vaud organised its army in 1819. As such, it violates the heraldic rule of tincture which states that gold (or yellow) may not be placed upon silver (or white).
Most mass-produced flags are commonly 150x90cm / 5x3' or 90x60cm / 3x2', which will often vary from the official size ratio. We now offer a custom-manufactured official size option for our many of our flags.
