The national flag of the Republic of Chile, known as the Solitary Star, was officially adopted on October 18, 1817.3 It is divided into two horizontal stripes: the upper one is blue and white while the lower one is red; in the blue corner there is a five-pointed star in white.
The most common interpretations of the use of the colors of the flag would attribute to blue the representation of the sky, to white the snow-capped peaks of the Andes mountain range, and to red the blood shed by national heroes in the war for independence. In turn, the star would symbolize the three powers of the Chilean State (Executive, Legislative and Judicial) that ensure the integrity of the nation, and its uniqueness would be a reference to the unitary State – unlike, for example, the multiple stars of the flag of the United States representing the federal state. However, considering the verses from Canto XXI of the epic poem La Araucana (1569), the colors of the current Chilean flag would go back to the tricolor bands used by the Mapuche toquis during the Arauco War against the Spanish Conquest, 5 while that the pentagram would represent the “star of Arauco” —the planet Venus— according to Bernardo O’Higgins.
Since 1939, the Armed Forces of Chile have carried out the Pledge of Allegiance ceremony on July 9 9 10 n 2 —when the 77 soldiers who died in the Battle of La Concepción in 1882, during the War of the Pacific, are commemorated— , a date that was designated in 1974 as the “Official Day of the National Flag.” 3 On the other hand, October 18 was designated in 1972 as the “Day of Celebration of the National Shield and Flag,” although this anniversary has fallen in oblivion.
