The flag of Solomon Islands was adopted in 1977, replacing the British Blue Ensign defaced with the arms of the British Solomon Islands Protectorate. It has been the flag of Solomon Islands since 18 November of that year, eight months before the country gained independence. It consists of a thin, yellow stripe dividing diagonally from the lower hoist-side corner. The upper triangle is blue and the canton charged with five white stars; the lower triangle is green. Although the number of provinces has increased from the five original provinces, the number of stars on the flag remains unchanged.
