St Patrick's Day is a holiday, and even the most stubborn Americans can't help but want to wear green clothes or drink green beer. But what if everyone wears blue every March 17? After all, the earliest description of St. Patrick showed that he was wearing blue, not green. When George III created a new Knight's Medal for the Kingdom of Ireland, its official color was sky blue, which was called "Saint Patrick's Blue". Saint Patrick's medal, Saint Patrick's medal and Saint Patrick's medal are the earliest images of Saint Patrick.

The meaning of blue can be traced back to the early Irish mythology, when Ireland's sovereignty, Flaitheas? Yilan is usually depicted as a woman in a blue robe. According to legend, this description is based on 10 century Golm Queen, an ancient Irish word "gorm" and "sovereignty". However, in his Celtic Culture: An Encyclopedia of History, John T. Koch believes that this legend has almost no factual basis. He wrote, "Golm Fellers should not be regarded as a living representative of the goddess of sovereignty in mythology and literature.

When Henry VIII ascended the throne, after more than 300 years of British rule in Ireland, he took measures to strengthen the control of the island, and declared himself king of Ireland at 154 1, making it a part of Britain and giving it his own coat of arms. This is the first time that blue is officially associated with Ireland, and the golden harp is used on the blue background; Today, the same sign can be seen in the Irish Constitution and the presidential flag.

This is the current design of the Irish presidential flag. (Wikimedia Commons), but due to the interference of Tudor king and the establishment of St. Patrick's Order by George III, it lasted until the18th century, and blue was defiled as a color of Ireland. From the end of 18 to the 20th century, with the deepening of the gap between the Irish and the British crown, green and St. Patrick's clover became the symbols of Irish identity and rebellion.

After Ireland established a free country, the order quickly collapsed. Technically, this order still exists, but there are no remaining knights. Its only two members are the head of state Elizabeth II and an officer, King Ulster Ames. Now, the members of the choir of St. Patrick's Cathedral are still wearing St. Patrick's blue robes and full of members of the choir of St. Patrick's Cathedral.
