Why does Scotland have its own flag if it is part of the UK?

Scotland has its own flag, the Saltire or St Andrew's Cross, because it is a nation within the United Kingdom, with its own distinct history, culture, and traditions. Scotland is one of four countries with devolved assemblies that form the United Kingdom, the others being Wales, Northern Ireland, and England.

Each of these countries has its own flag, flown alongside the Union Jack, which represents the unity of the four nations. Scotland's flag, with its white diagonal cross on a dark blue background, dates back to the 12th century, and is an enduring symbol of Scottish identity and national pride.
