A constitutional referendum was held on 28 September 1958 as part of a wider referendum across the French Union (and France itself) on whether to adopt the new French constitution; colonies voting to accept it would become part of the new French Community; if rejected, the territory would be granted independence.[4][5] More than 95% of voters of French Guinea voted against the constitution, with a turnout of 85.5%,[6] making it the only colony to vote no.[7]
