The national flag of England, known as St. George's Cross, has been the national flag since the 13th century. Originally the flag was used by the maritime state the Republic of Genoa. The English monarch paid a tribute to the Doge of Genoa from 1190 onwards, so that English ships could fly the flag as a means of protection when entering the Mediterranean. A red cross acted as a symbol for many Crusaders in the 12th and 13th centuries. It became associated with Saint George, along with countries and cities, which claimed him as their patron saint and used his cross as a banner. Since 1606 the St George's Cross has formed part of the design of the Union Flag, a Pan-British flag designed by King James I.
There are numerous other symbols and symbolic artefacts, both official and unofficial, including the Tudor rose, the nation's floral emblem, the White Dragon and the Three Lions featured on the nation's coat of arms. The Tudor rose was adopted as a national emblem of England around the time of the Wars of the Roses as a symbol of peace. It is a syncretic symbol in that it merged the white rose of the Yorkists and the red rose of the Lancastrians—cadet branches of the Plantagenets who went to war over control of the royal house. It is also known as the Rose of England. The oak tree is a symbol of England, representing strength and endurance. The term Royal Oak is used to denote the escape of King Charles II from the grasps of the parliamentarians after his father's execution; he hid in an oak tree to avoid detection before making it safely into exile.
The national coat of arms of England, featuring three lions dates back to its adoption by Richard the Lionheart from 1198–1340. They are described as gules, three lions passant guardant or and provide one of the most prominent symbols of England; it is similar to the traditional arms of Normandy. England does not have an official designated national anthem, as the United Kingdom as a whole has God Save the Queen. However, the following are often considered unofficial English national anthems: Jerusalem, Land of Hope and Glory (used for England during the 2002 Commonwealth Games), and I Vow to Thee, My Country. England's National Day is St George's Day, as Saint George is the patron saint of England, it is held annually on 23 April.
