The cross of Saint George is a straight red cross on a white background. It derives from the medieval cult of Saint George, a Christian martyr from the early 4th century who became the patron saint of several European cities, orders, and territories. In England, the symbol gained military importance under the Plantagenets before becoming the national flag at the beginning of the 16th century.

Who was George really?
English Heritage notes that George was probably a Greek-speaking Christian from the Roman Near East who died a martyr around 303.
He was neither English nor a medieval knight. His reputation spread long after his death.
Why is his emblem red on white?
The red cross became one of the heraldic attributes associated with the saint and with armies under his patronage.
The precise origin of the combination cannot be reduced to a single decree, but its use in England is clearly attested in the Middle Ages.
How did the English sovereigns adopt it?
English Heritage states that Edward I had banners bearing the emblem of Saint George and that Edward III greatly strengthened his cult.
The founding of the Order of the Garter under Edward III linked the saint to the kingdom’s most prestigious chivalric institution.
When did it become the flag of England?
The cross was already used militarily long before the modern era, but English Heritage places its transformation into a national flag at the beginning of the 16th century.
It later became part of the Union Jack alongside the crosses of Saint Andrew and, later, Saint Patrick.
Why is the symbol not limited to England?
Saint George is also a patron saint or important figure in Genoa, Venice, Catalonia, Georgia, Ethiopia, and elsewhere.
A red cross on white can therefore reflect several heraldic histories depending on the context.
The cross of Saint Andrew offers another example of an apostolic cross that became a national emblem.
