The origin of the red-white-blue tricolour is not entirely clear; some sources suggest that it developed merely as a variant of orange-white-blue because the orange dye would tend to fade to red over time.
However, there have also been suggestions to the effect that the red-white-blue flag might predate the introduction of the Prince's Flag in the 1570s. Thus, Muller (1862) suggested that the colours were taken from the coat of arms of the Bavarian house, the rulers of the county of Holland during 1354–1433, who used the Bavarian coat of arms quartered with the arms of the counts of Holland.[1]
During the early part of the First Stadtholderless Period (1650–1672), the government of the Dutch Republic wanted to appease the republican government of the Commonwealth of England, and because the colour orange was associated with the House of Stuart, the orange-white-blue Prince's Flag was banned in 1652, replaced by the red-white-blue "States Flag".[2]
According to de Waard (1900), the Dutch navy between 1588 and 1630 always displayed the Prince's Flag, and after 1663 always the State's Flag, but both flag variants were in use during the period of 1630–1662.[3]
It appears that prior to 1664, the red-white-blue tricolour was commonly known as the "Flag of Holland" (Hollandsche Vlag).
In 1664, the States of Zeeland complained about this, and a resolution of the States-General introduced the name "States Flag" (Statenvlag).[4]
In the 1930s, the supporters of the NSB chose the orange-white-blue and the Prince's Flag as their symbol. Queen Wilhelmina in 1937 signed a Royal Decree that the colours red, white and blue are set as the official colours of the Dutch flag, partly as a signal directed at the NSB.
