Guinea‑Bissau’s flag (24 September 1973) mirrors PAIGC symbolism: a red hoist band with a black star, and yellow over green at the fly. Red marks the liberation struggle; yellow resources and the sun; green land and hope; the black star African unity. Ratio 1:2; protocol and law govern display and colours.
Adopted at unilateral independence on 24 September 1973, Guinea‑Bissau’s flag transposes party iconography into national heraldry.
Design
and symbolism. A vertical red hoist band charged with a black five‑pointed star stands beside two equal horizontal bands of yellow over green. Red recalls blood shed for freedom; yellow the sun and resources; green fertile land and hope; the black star African unity and liberation.
Standards and protocol
Ratio 1:2; colour specifications and star geometry are defined. Protocol covers precedence, half‑masting, and dignified retirement; misuse is penalised.
Continuity
and presence. The design has remained stable through political shifts, featuring centrally in civic rituals, schools, and international representation.
Thus the national banner preserves the liberation movement’s visual grammar within a legal, civic frame.
