Quick Summary

The Cross of St. Andrew is an emblem, most famously represented by the white saltire on a blue background, which is the flag of Scotland. According to legend, King Angus of Scotland saw a white saltire in the sky before a battle, which inspired its adoption. The first confirmed use of the symbol dates to 1286 on a Scottish government seal.1

St. Andrew himself is iconographically represented with an X-shaped cross, similar to the one on the Scottish flag. This association stems from late medieval accounts describing his crucifixion on an X-shaped cross and his status as the patron saint of Scotland. The saltire was also combined with the Cross of St. George to form early versions of the Union Jack when Scotland and England shared monarchs.21
