It is one of the simplest national flags in the world.
The red and white colors are derived from the coat of arms of the House of Grimaldi, the princely family that has ruled over Monaco since the 13th century.
The official flag was adopted on April 4, 1881.
The flag is nearly identical to that of Indonesia (differing only slightly in its proportions and the specific shade of red) and is the reverse of the flag of Poland.
In addition to the red-and-white bicolour, the government also uses a state flag—featuring the full coat of arms of Monaco on a white background—for official buildings and the Prince's Palace.
