As an English name it has been very popular since the Middle Ages. It was the top name for girls in England and Wales in the 1920s, 30s and 40s, but it declined in the latter half of the 20th century.
Other saints by this name include a queen of Scotland and a princess of Hungary. It was also borne by Queen Margaret I of Denmark, who united Denmark, Sweden, and Norway in the 14th century. Famous literary bearers include American writer Margaret Mitchell (1900-1949), the author of Gone with the Wind, and Canadian writer Margaret Atwood (1939-). Others include American anthropologist Margaret Mead (1901-1978) and British prime minister Margaret Thatcher (1925-2013).
The popularity of the saint led to the name being used by nine Byzantine emperors, including Michael VIII Palaeologus who restored the empire in the 13th century. It has been common in Western Europe since the Middle Ages, and in England since the 12th century. It has been borne (in various spellings) by rulers of Russia (spelled Михаил), Romania (Mihai), Poland (Michał), and Portugal (Miguel).
In the United States, this name rapidly gained popularity beginning in the 1930s, eventually becoming the most popular male name from 1954 to 1998. However, it was not as overwhelmingly common in the United Kingdom, where it never reached the top spot.
Famous bearers of this name include the British chemist/physicist Michael Faraday (1791-1867), musician Michael Jackson (1958-2009), and basketball player Michael Jordan (1963-).
In England and elsewhere in Europe during the Middle Ages this name was used in honour of the saint. However, it was not generally given in Ireland before the 17th century because it was considered too sacred for everyday use. It has since become very common there.
