The name has been used by kings of Scotland, Poland and Yugoslavia, emperors of Russia, and eight popes. Other notable bearers include English poet Alexander Pope (1688-1744), American statesman Alexander Hamilton (1755-1804), Scottish-Canadian explorer Alexander MacKenzie (1764-1820), Russian poet Alexander Pushkin (1799-1837), and Alexander Graham Bell (1847-1922), the Scottish-Canadian-American inventor of the telephone.
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.
This was the name of a 13th-century Italian saint who made clothes for the poor. As an English name, it has never been common.
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.
