The flag of England is the St George's Cross, a red cross on a white background. St George became the patron saint of England in the 14th century, and the red cross has been associated with English identity since the Crusades. The design forms the basis of the Union Jack.
The St George's Cross was used by English soldiers as early as the Crusades in the 12th century, making it one of the oldest national emblems still in use.
Adopted: 1606
