Flag of Chile
The flag of Chile consists of two equal-height horizontal bands of white and red, with a blue square the same height as the white band in the canton, which bears a white five-pointed star in the center. It was adopted on 18 October 1817. The Chilean flag is also known in Spanish as La Estrella Solitaria[1] (The Lone Star).

Design of the flag used from 1818 to 1912 with the star tilted.
It has a 3:2 ratio between length and width, it is divided horizontally into two bands of equal height (the lower being red). The upper area is divided once: into a square (blue), with a single centered white star; and into a rectangle (white), whose lengths are in proportion 1:2. It is in the stars and stripes flag family.
The star represents Venus, significant to the country's indigenous Mapuches,[2] symbolizing a guide to progress and honor while other interpretations say it refers to an independent state; blue symbolizes the sky and the Pacific Ocean, white is for the snow-covered Andes, and red stands for the blood spilled to achieve independence.[3]
According to the epic poem La Araucana, the colors were derived from those from the flag flown by the Mapuche during the Arauco War. "Flag Day" is held each year on the ninth of July to commemorate the 77 soldiers who died in the 1882 Battle of La Concepción.
Respect due to the flag[edit]
Article 22 of the 1980 Constitution of Chile states that all inhabitants of the Republic owe respect to Chile and to its national emblems. The national emblems of Chile are the national flag, the coat of arms of the Republic and the national anthem. Pursuant to article 6 of the State Security Act of Chile (Decreto No. 890 de 1975), it is a felony against the public order to publicly mistreat the flag, the coat of arms, the name of the motherland or the national anthem.
