How their governments are structured
Antigua and Barbuda is a constitutional monarchy; Barbados is a parliamentary republic. The second split is how the executive is chosen. Antigua and Barbuda's executive does not fit cleanly into the standard parliamentary, presidential, or one-party templates. Barbados runs a parliamentary system: the head of government (a prime minister or chancellor) holds office only as long as they keep the confidence of the lower house, and a successful no-confidence vote forces resignation or new elections. The practical effect is that Antigua and Barbuda and Barbados produce executives with different routes to power and different ways of losing it. Antigua and Barbuda keeps a hereditary monarch as head of state — a largely ceremonial role distinct from the head of government — while Barbados fuses or separates these roles within an elected office instead. The substantive difference is mostly symbolic and constitutional-emergency reserve powers, not day-to-day politics.
