Since the post-emancipation period, or even before, Africans and other oppressed persons in the Caribbean have used this method to protest or highlight injustice or idiocy of people in power. In Trinidad & Tobago, it’s known as Jouvert from the creole for jour ouvert – the opening of day or dawn – because it was only permitted to happen from the wee hours of the morning on the first day of carnival. So my friends, people with mostly individually conceived, homemade costumes and signs making satirical statements about political and social issues have been having their own rallies to restore sanity and fear for more than a century before what happened today.
