The flag of Cuba was aopted on May 20, 1902, containing a field with five blue and white stripes, and a red triangle at the hoist with a white 5-pointed star. The flag was designed in 1848 for the liberation movement, which sought to detach Cuba from Spain and make it into a state of the US. "La Estrella", the Lone Star, represented another star that would be added to "the splendid North American constellation." The triangle is derived from the Masonic symbol for equality, while the 5 stripes stand for the 5 provinces of the time. The flag was briefly hoisted in 1850 at Cardenas but was not officially adopted until 1902, when independence was granted by the US. Ironically, the flag's design is based on the US Stars and Stripes.
