As an English name it was highly popular from the Middle Ages until the 17th century. It was revived in the 19th century and was common into the 20th, but it fell into decline after the 1930s. It last appeared on the American top 1000 rankings in 1972.
This name was borne by the heroine of Lewis Carroll's novels Alice's Adventures in Wonderland (1865) and Through the Looking Glass (1871).
The popularity of the name in continental Europe was due to the fame of Charles the Great (742-814), commonly known as Charlemagne, a king of the Franks who came to rule over most of Europe. His grandfather Charles Martel had also been a noted leader of the Franks. It was subsequently the name of several Holy Roman emperors, as well as rulers of France, Spain, Portugal, Sweden and Hungary (in various spellings). After Charlemagne, his name was adopted as a word meaning "king" in many Eastern European languages, for example Czech král, Hungarian király, Russian король (korol), and Turkish kral.
The name did not become common in Britain until the 17th century when it was borne by the Stuart king Charles I. It had been introduced into the Stuart royal family by Mary Queen of Scots, who had been raised in France. Two other kings of the United Kingdom have borne this name, including the current monarch.
Other famous bearers include naturalist Charles Darwin (1809-1882) who revolutionized biology with his theory of evolution, novelist Charles Dickens (1812-1870) who wrote such works as Great Expectations and A Tale of Two Cities, French statesman Charles de Gaulle (1890-1970), and American cartoonist Charles Schulz (1922-2000), the creator of the Peanuts comic strip.
Famous bearers include the uncrowned English queen Lady Jane Grey (1536-1554), who ruled for only nine days, British novelist Jane Austen (1775-1817), who wrote Sense and Sensibility and Pride and Prejudice, British primatologist Jane Goodall (1934-), and American actress Jane Fonda (1937-). This is also the name of the central character in Charlotte Brontë's novel Jane Eyre (1847), which tells of Jane's sad childhood and her relationship with Edward Rochester.
Apart from royalty, this name was only moderately popular in France during the Middle Ages. After the French Revolution, when Louis XVI was guillotined, it became less common.
The Normans brought the name to England, where it was usually spelled Lewis, though the spelling Louis has been more common in America. Famous bearers include French scientist Louis Pasteur (1822-1895), French actor Louis de Funès (1914-1983), Scottish author Robert Louis Stevenson (1850-1894), who wrote Treasure Island and Dr Jekyll and Mr Hyde, and American jazz musician Louis Armstrong (1901-1971).
During the late Middle Ages this name was typically among the five most common for English males (with John, William, Robert and Thomas). It remained fairly popular through to the modern era, peaking in the United States in the 1940s and in the United Kingom a bit later, and steadily declining since that time.
Famous bearers include two German opera composers, Richard Wagner (1813-1883) and Richard Strauss (1864-1949), as well as British explorer Richard Burton (1821-1890), American president Richard Nixon (1913-1994), American physicist Richard Feynman (1918-1988), British actor Richard Burton (1925-1984) and American musician Little Richard (1932-2020).
This name was later borne by three other English kings, as well as rulers of Scotland, Sicily (of Norman origin), the Netherlands and Prussia. Other famous bearers include William Wallace, a 13th-century Scottish hero, and William Tell, a legendary 14th-century Swiss hero (called Wilhelm in German, Guillaume in French and Guglielmo in Italian). In the literary world it was borne by dramatist William Shakespeare (1564-1616), poet William Blake (1757-1827), poet William Wordsworth (1770-1850), dramatist William Butler Yeats (1865-1939), author William Faulkner (1897-1962), and author William S. Burroughs (1914-1997).
In the American rankings (since 1880) this name has never been out of the top 20, making it one of the most consistently popular names (although it has never reached the top rank). In modern times its short form, Liam, has periodically been more popular than William itself, in the United Kingdom in the 1990s and the United States in the 2010s.
