The national flag of Cuba is a longstanding emblem of Cuban identity and independence. Its familiar layout—a red equilateral triangle at the hoist containing a white five‑pointed star, and five alternating horizontal stripes—has been used since the 19th century and formally adopted when the republic was established. For official descriptions and reproductions see official references.

Design and elements

The flag combines simple geometric elements arranged for high recognizability. Key components include:

  • Stripes: Five equal horizontal bands alternating three blue and two white (stripe layout).
  • Blue color: The three blue stripes historically correspond to territorial divisions of the island (blue stripes).
  • White color: The two white stripes are commonly taken to express purity of the civic ideals (white stripes).
  • Red triangle: An equilateral triangle at the hoist, colored red, provides a focal element (red triangle).
  • Star: A single white, five‑pointed star sits in the triangle, sometimes called the "Lone Star" (the star).

Symbolism

Interpretations of the flag's colors and shapes are rooted in the independence movement. The three blue stripes are commonly associated with historical territorial divisions; the white stripes suggest ideals such as justice and purity. The red triangle is often described as symbolizing sacrifice, courage, and the blood shed in the struggle for independence, while the lone white star stands for sovereignty and freedom. These meanings are widely cited in historical accounts and public tradition (symbolic explanations).

History and adoption

The design dates to the mid‑19th century, created in the context of independence campaigns. It was used by revolutionary forces before official statehood and later became the national flag when Cuba gained independence and established a republican government in the early 20th century. Variants and proposals appeared during different uprisings, but the basic composition remained constant.

Uses, protocol, and notable facts

The flag is flown at government buildings, schools, and public ceremonies and is treated as a national symbol with prescribed respect and protocol. Notable facts include its visual relationship with other Caribbean flags—most famously the Puerto Rican flag, which inverts some colors—and its continued role as a powerful emblem for both domestic civic identity and expatriate communities.
