Óengus II

The traditional flag of Scotland, known as the Saltire or St. Andrew's Cross, is said to have its origins in a 832 CE battle between the Picts and the Angles. Legend holds that the night before the battle, Saint Andrew, the patron saint of Scotland who was crucified on an X-shaped cross, appeared to the Pictish king, Oengus II, promising victory. On the day of battle, a white cross, resembling Saint Andrew's crucifixion cross, formed from clouds against a blue sky, inspiring the Picts to a triumphant victory. This divine sign led to the adoption of the white cross on a blue background as Scotland's emblematic flag.
