The Gothic order of architecture, which was perfected during this period, had a decided influence upon the painting and sculpture of the time; but this influence was not felt until Gothic architecture had reached a high point in its development. France was now the leading country of the world, and Paris came to be the most important of all cities: it was the centre from which went forth edicts as to the customs of society, the laws of dress and conduct, and even of the art of love. From France came the codes of chivalry, and the crusades, which spread to other lands, originated there.
