The first major movement of Medieval art, the style known as "Romanesque" can be used to cover all derivations of Roman architecture in the West, from the fall of Rome (c.450 CE) until the advent of the Gothic style around 1150. Traditionally, however, the term refers to the specific style of architecture, along with sculpture and other minor arts that appeared across France, Germany, Italy and Spain during the 11th century. Richer and more grandiose than anything witnessed during the era of Early Christian Art, the Romanesque style is characterized by a massiveness of scale, reflecting the greater social stability of the new Millennium, and the growing confidence of the Christian Church in Rome, a Church whose expansionism set in motion the Crusades to free the Holy Land from the grip of Islam. Later, the success of the Crusaders and their acquisition of Holy Relics stimulated further construction of new churches across Europe in the fully fledged Romanesque style of architecture (Norman architecture in Britain and Ireland). In turn this building program produced a huge demand for decorative religious art, including sculpture, stained glass and ecclesiastical metalwork of all types. By the 12th century certain architects and sculptors had become highly sought-after by ecclesiastical and also secular patrons.
