Monarchy of Barbados
The person who is the Barbadian sovereign is equally shared with 15 other monarchies (a grouping, including Barbados, known informally as the Commonwealth realms) in the 52-member Commonwealth of Nations, with the monarch residing predominantly in the oldest and most populous realm, the United Kingdom, and a viceroy—the Governor-General of Barbados—acting as the sovereign's representative in Barbados. This arrangement emerged among the older realms after the end of the First World War and is governed by the Statute of Westminster 1931. Since then, the pan-national Crown has had both a shared and a separate character and the sovereign's role as monarch of Barbados has been, since Barbados' independence in 1966, distinct to his or her position as monarch of any other realm, including the United Kingdom. Only Barbadian ministers of the Crown may advise the sovereign on matters of the Barbadian state. The monarchy thus ceased to be an exclusively British institution and in Barbados became a Barbadian, or "domesticated", establishment.
This division is illustrated in a number of ways: The sovereign, for example, holds a unique Barbadian title and, when she is acting in public specifically as a representative of Barbados, she will use, where possible, Barbadian symbols, including the country's national flag, unique royal symbols, and the like. The sovereign similarly only draws from Barbadian coffers for support in the performance of her duties when in Barbados or acting as Queen of Barbados abroad; Barbadians do not pay any money to the Queen, either towards personal income or to support royal residences outside of Barbados. This applies equally to other members of the Royal Family. Normally, tax dollars pay only for the costs associated with the governor-general in the exercise of the powers of the Crown, including travel, security, residences, offices, and ceremonies.
