This document provides an overview of several topics from the High Middle Ages: 1) The Crusades were launched in response to Muslim control of holy sites, and stimulated European trade with Asia. 2) Trade revived across Europe through routes established by the Vikings, Hanseatic League, and Italian ships. This led to the growth of towns. 3) As towns grew and farming methods changed, serfdom declined and more people left manors for independent life in towns. 4) The document outlines literature, including romances and plays, common in medieval Europe.
