Even before attaining its independence from Spain, Cuba had several constitutions either proposed or adopted by insurgents as governing documents for territory they controlled during their war against Spain. Cuba has had several constitutions since winning its independence. The first constitution since the Cuban Revolution was drafted in 1976 and has since been amended. In 2018, Cuba became engaged in a major revision of its constitution. The current constitution was then enacted in 2019.
