This name was borne by a 12th-century empress of the Latin Empire in Constantinople, who was originally from Flanders. It was also used by her descendants in the royal families of Hungary (spelled Jolánta) and Spain (sometimes spelled Violante). The Blessed Yolanda of Poland was a daughter of Béla IV of Hungary who married a Polish duke. It was also borne by Yolanda of Vianden, a 13th-century countess from Luxembourg who joined a convent against her parents' wishes, later becoming the subject of medieval legend. Another notable bearer was a 15th-century duchess of Lorraine, the subject of the opera Iolanta (1892) by Pyotr Ilyich Tchaikovsky.
The name received a boost in popularity after it was borne by the antagonist in the horror movie The Ring (2002).
The name was common in France during the Middle Ages, and was introduced from there to England, though it eventually became rare. Interest in it was revived by the character Melanie Wilkes from the novel Gone with the Wind (1936) and the subsequent movie adaptation (1939).
American writers Jack London (1876-1916) and Jack Kerouac (1922-1969) were two famous bearers of this name. It is also borne by the actor Jack Nicholson (1937-) and the golfer Jack Nicklaus (1940-). Apart from Nicklaus, none of these famous bearers were given the name Jack at birth.
In the United Kingdom this form has been bestowed more frequently than John since the 1990s, being the most popular name for boys from 1996 to 2008.
The name was originally used among early Christians in honour of the saint, as opposed to the classical character.
