The flag of Galicia appeared for first time in the 19th century, probably based on the colours of the ancient medieval flags of the Kingdom of Galicia. Originally, the flag was probably a blue St Andrew's Cross over a white field – St Andrew is one of the most popular saints in Galicia. The Coat of Arms of Galicia was actually the former flag of the Kingdom of Galicia. The colors blue, white and gold were always related with Galicia.
