The Middle Ages is the European historical period between Antiquity and the Modern Era, which is considered to begin with the collapse of the Western Roman Empire (476 AC), and to end with the discovery of America (1492).

 The Late Middle Ages, from the fourteenth to the fifteenth century, saw a growing general power and the revival of commercial interests, especially after the plague of the fourteenth century.
