The Prince's Flag is a Dutch flag, first used in the Dutch Revolt during the late 16th century. The Prince's Flag is based on the Flag of Prince William of Orange-Nassau, hence the name. The colours are orange, white and blue. On the basis of the French names of these colours, orange-blanc-bleu, the flag is also referred to by the Dutch rhymes oranje-blanje-bleu and ranje-blanje-bleu.
History
The colours orange, white and blue are associated with William Prince of Orange. William is reported to have used these colours as early as 1577, as part of his procession entering Ghent. Jacob Duym also reports that in the siege of Leiden in 1574, the Dutch officers wore orange-white-blue brassards. From this, Rey concludes that the combination of orange-white-blue was certainly used by the Prince of Orange in the 1570s. The first reference to a naval flag in these colours dates to 1587, when the Admiralty of Zeeland ordered these flags to fly on their warships. The naval flag was used by the Watergeuzen, the pro-Dutch privateers during the Dutch Revolt. According to de Waard, the Dutch navy between 1588 and 1630 always displayed the Prince's Flag, and after 1663 always the red-white-blue Statenvlag. The latter was introduced gradually during the 1630s to 1650s, and named "States' Flag" in 1664. During the 17th century the Prince's Flag was hoisted on the Castle of Good Hope and saluted by incoming ships. The orange-white-blue flag formed the basis for the South African flag of 1928. It is also the basis for the flags of New York City and Albany, New York. After the republican Patriots, aided by the French, seized control over the Netherlands in 1795, the Prince's Flag was forbidden and the red-white-blue flag became the only official flag, to the content of the French, analogous as they were to their own tricolour, chosen just a few months earlier. In the following period of the Kingdom of Holland, there was also no place for Orange and the BonapartistKing Louis I chose red. In 1813, when the French were expelled and the Netherlands regained its independence, the Prince of Orange returned to the country from England. The Prince's Flag saw a short revival; in order to demonstrate the attachment of the people to the House of Orange, both this flag and the red-white-blue flag fluttered on the roofs. In the same year, for the first time, the red-white-blue flag was flown with an orange pennant, which has remained the custom in the Netherlands. Whether the Prince's Flag or the red-white-blue flag should be the national flag was left undecided, although the Prince of Orange, later King William I, preferred the latter. In the 1930s, the supporters of the National Socialist Movement in the Netherlands chose the orange-white-blue and the Prince's Flag as their symbol. Queen Wilhelmina in 1937 signed a Royal Decree that the colors red, white and blue are set as the official colors of the Dutch flag.
