According to ancient heraldic tradition, the color white in a flag or design represents peace and honesty. Blue represents vigilance, truth, loyalty, perseverance, and justice. Red, in turn, represents hardiness, strength, bravery and valor.
The Cuban flag is red, white and blue, with a red triangle and a white star on the left side. The rest of the flag is occupied by five alternating horizontal stripes of blue and white. There are three blue stripes (the first and last stripes at the top and bottom of the flag are blue) and two white stripes.
In addition to the generic symbolism, each of the elements (stripes, triangle and star) has a symbolism that is unique to Cuban history. The three blue stripes on the flag refer to three old divisions of the island. The white stripes refer to the strength of the independent ideal. The red triangle stands for the values of equality, fraternity and freedom and also for the blood that was spilled during the struggle for independence. The lone star on the flag is representative of the absolute independence of the Cuban people.
The Cubans accepted this flag as the country's national flag on May 20, 1902, and maintained it despite the revolution.
