A History Of European Art
International Gothic is a phase of Gothic art which developed in Burgundy, Bohemia, France and northern Italy in the late 14th century and early 15th century. It then spread very widely across Western Europe, hence the name for the period, which was introduced by the French art historian Louis Courajod at the end of the 19th century.
In this period, artists and portable works such as illuminated manuscripts traveled widely around the continent, creating a common aesthetic among the royalty and higher nobility and considerably reducing the variation in national styles among works produced for the courtly elites. The main influences were northern France, the Duchy of Burgundy, the Imperial court in Prague, and Italy. Royal marriages such as that between Richard II of England and Anne of Bohemia also helped to spread the style.
It was initially a style of courtly sophistication, but somewhat more robust versions spread to art commissioned by the emerging mercantile classes and the smaller nobility. In Northern Europe "Late Gothic" continuations of the style, especially in its decorative elements, could still be found until the early 16th century, as no alternative decorative vocabulary emerged to replace it before Renaissance Classicism. Usage of the terms by art historians varies somewhat, with some using the term more restrictively than others. Some art historians feel the term is "in many ways ... not very helpful.. since it tends to skate over both differences and details of transmission."
