Arthur is the name of the central character in Arthurian legend, a 6th-century king of the Britons who resisted Saxon invaders. He may or may not have been based on a real person. He first appears in Welsh poems and chronicles (perhaps briefly in the 7th-century poem Y Gododdin and more definitively and extensively in the 9th-century History of the Britons [1]). However, his character was not developed until the chronicles of the 12th-century Geoffrey of Monmouth [2]. His tales were later taken up and expanded by French and English writers.
The name came into general use in England in the Middle Ages due to the prevalence of Arthurian romances, and it enjoyed a surge of popularity in the 19th century. Famous bearers include German philosopher Arthur Schopenhauer (1788-1860), mystery author and Sherlock Holmes creator Arthur Conan Doyle (1859-1930), and science-fiction author Arthur C. Clarke (1917-2008).
After the Norman Conquest this name became common in England. It was revived in the 18th century, perhaps in part due to Matthew Prior's 1709 poem Henry and Emma [2]. It was also used by Jane Austen for the central character, the matchmaker Emma Woodhouse, in her novel Emma (1816).
In the United States, it was third in rank in 1880 (behind only the ubiquitous Mary and Anna). It declined steadily over the next century, beginning another rise in the 1980s and eventually becoming the most popular name for girls in 2008. At this time it also experienced similar levels of popularity elsewhere, including the United Kingdom (where it began rising a decade earlier), Germany, France, Italy, Spain, Scandinavia and the Netherlands. Famous bearers include the actresses Emma Thompson (1959-), Emma Stone (1988-) and Emma Watson (1990-).
