“The Monarchy of Jamaica is a constitutional system of government in which a hereditary monarch is the sovereign of Jamaica, forming the core of the country’s Westminster-style parliamentary democracy. The terms Crown in Right of Jamaica, Her Majesty in Right of Jamaica, or The Queen in Right of Jamaica may also be used to refer to the entire executive of the government of Jamaica. Though the Jamaican Crown has its roots in the British Crown, it has evolved to become a distinctly Jamaican institution, represented by its own unique symbols.
The present monarch is Queen Elizabeth II—officially titled Queen of Jamaica—who has reigned since 6 August 1962. She, her consort, and other members of the Royal Family undertake various public and private functions across Jamaica and on behalf of the country abroad. However, the Queen is the only member of the Royal Family with any constitutional role, holding ultimate executive authority though her Royal Prerogative remains bound by laws enacted by her in parliament and by conventions and precedents, leaving the day-to-day exercise of executive power to her Cabinet. While several powers are the sovereign’s alone, most of the royal constitutional and ceremonial duties in Jamaica are carried out by the Queen’s representative, the governor-general.”
