The flag of Saint Kitts and Nevis consists of a yellow-edged black band containing two white stars that divide diagonally from the lower hoist-side corner, with a green upper triangle and red lower triangle. Adopted in 1983 to replace the flag of Saint Christopher-Nevis-Anguilla, it has been the flag of the Federation of Saint Kitts and Nevis since the country gained independence that year. Although the flag utilises the colours of the Pan-Africanist movement, the symbolism behind them is interpreted differently. The three islands later became part of the West Indies Federation in 1958; after this dissolved four years later, they were granted the status of the associate state as Saint Christopher-Nevis-Anguilla. However, Anguilla decided to secede from the federation in 1969, owing to fears that their population, which was already small, would be further marginalised in parliament. This was eventually formalised in 1980, and a new flag for the remaining parts of the federation was needed, since the symbolism of the previous flag centred on the concept of a union of three.
