“Which nation became a republic by abolishing its monarchy in November 2021?”

"In November 2021 Barbados transitioned from a constitutional monarchy to a republic ending centuries of British monarchical rule. This historic move marked by the inauguration of President Sandra Mason symbolized national sovereignty and cultural independence. Barbados retained its membership in the Commonwealth reflecting its commitment to global partnerships. The transition highlighted the country’s progress in defining its post-colonial identity while maintaining strong diplomatic ties. This shift is part of a broader trend among former colonies reevaluating their governance structures with Barbados setting a precedent for others in the Caribbean."
