A drapeau tricolore with vertical red, white and blue stripes was approved by the Constituent Assembly on 24 October 1790. Simplified designs were used to illustrate how the revolution had broken with the past. The order was reversed to blue-white-red, the current design, by a resolution passed on 15 February 1794.
The constitutions of 1946 and 1958 instituted the "blue, white, and red" flag as the national emblem of the Republic.
