The Union Jack

The Union Jack is the national flag of the United Kingdom, symbolizing the union of England, Scotland, and Ireland. It combines three older flags: England's St. George's Cross (a red cross on a white background), Scotland's St. Andrew's Cross (a white saltire on a blue background), and Ireland's St. Patrick's Cross (a red saltire on a white background). These elements are overlaid to represent the unity of these nations under one flag. The design is a symmetrical and distinctive pattern used in various British contexts, embodying the country's history and political unity.
