Flags have existed for over 3000 years. The earliest flags were wooden or metal poles topped with a carving. About 2000 years ago pies of fabric were added to some poles for decoration. Over the next 500 years the free-flying part of the flag became more important.
Every country today has its own flag. Many groups and organizations also have a flag which stands for, or symbolizes, the aims of the group.
The flag depicts (描绘) a world map, centered on the north pole. The map is surrounded by an olive (橄榄) wreath (花环) symbolizing peace and co-operation. The flag is blue and white.
