Union Jack Flag - Official Flag of the United Kingdom #3586573 (License: Personal Use)

The Union Jack is the national flag of the United Kingdom, formed by superimposing the red cross of St George (England), the white saltire of St Andrew (Scotland), and the red saltire of St Patrick (Northern Ireland). Its asymmetrical design ensures correct orientation, with the broader white diagonal bands positioned above the red ones in the upper-left and lower-right quadrants. First adopted in 1801 after the Acts of Union with Ireland, it remains a globally recognized emblem of British identity and heritage.
