Elizabeth II

Upon her accession on 6 February 1952, Elizabeth became Head of the Commonwealth and queen regnant of seven independent Commonwealth countries: the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan and Ceylon. From 1956 to 1992, the number of her realms varied as territories gained independence and some realms became republics. At present, in addition to the first four of the aforementioned countries, Elizabeth is Queen of Jamaica, Barbados, the Bahamas, Grenada, Papua New Guinea, the Solomon Islands, Tuvalu, Saint Lucia, Saint Vincent and the Grenadines, Belize, Antigua and Barbuda, and Saint Kitts and Nevis. Her reign of 62 years is currently the second longest for a British monarch; only Queen Victoria, her great-great grandmother, has reigned longer, at over 63 years.
