In the late 1980s, several symbols from the Middle Ages were revived as Slovenian national symbols. Among them, the most popular are the so-called Slovene Hat which featured in the coat of arms of the Slovene March, and the Black Panther, a reconstruction of the supposed coat of arms of the Carolingian duchy of Carantania. After being used in the Flag of Slovenia, the graphical representation of Triglav has become recognised as a national symbol. Per the Constitution of Slovenia and the Slovenian act on national symbols, the flag of the Slovene nation is a white-blue-red flag without the coat-of-arms. The ratio of the width to height of the flag is one to two.
