A flag is like a special picture that represents a place or a group of people. The flag of Jersey is the flag that represents the small island of Jersey, which is part of the British Isles.
The flag has three colors: red, yellow, and blue. The top of the flag is red, which represents the English. The middle of the flag is yellow, which represents the Normans. The Normans were a group of people from France who took over Jersey in the past. The bottom of the flag is blue, which represents the Islanders. The Islanders are the people who were originally from Jersey.
The flag was created in 1979 and was officially adopted in 1981. It is used to represent the island and is flown on special occasions like Independence Day, which is the day that Jersey became independent from the Duchy of Normandy in 1204.
So, in short, the flag of Jersey is a special picture with three colors that represents the island of Jersey and its history.
