In 1949, George VI became the first Head of the Commonwealth, a symbol of the free association of the independent countries comprising the Commonwealth of Nations. On his death in 1952, Elizabeth became Head of the Commonwealth, and constitutional monarch of seven independent Commonwealth countries: the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan, and Ceylon. Her coronation in 1953 was the first to be televised. During her reign, which at 58 years is one of the longest for a British monarch, she became queen of 25 other countries within the Commonwealth as they gained independence. Between 1956 and 1992, half of her realms, including South Africa, Pakistan, and Ceylon (renamed Sri Lanka), became republics.
