A blue field with a white saltire that extends to the corners of the flag.
The flag of Hapatmitas, also known as Saint Duncan's Saltire (Cantuath: Saltire an Naoimh Donnachadh), is the national flag of Hapatmitas, which consists of a white saltire defacing a blue field. The first version of the Saltire flag was adopted on 24 June 1892 during the constitutional monarchy, whereas it was charged with the Crown of Finbarr which was formally used in all government entities prior to 1924. After the ratification of the 1924 constitution, a slightly altered version of the flag was adopted whereas the crown was removed as well as the choice of a lighter shade of blue. In 1950, after the end of the Hapatmitasian Civil War, the 1950 Constitution changed the flag, which presently has an even darker shade of blue than the flag before 1924, once again.
