Except for two institutions of the kind in Holland, Belgium is the only country in Europe in which these Béguinages have survived--all of them in Flanders. No institution of the present day recalls so vividly the conditions that existed at the time when Flanders was the name of a wild marsh country peopled by yet wilder men. In 877 the Emperor made the title of Count of Flanders hereditary--the oldest title of the kind in Europe. Baldwin II, son of Baldwin of the Iron Arm and the beautiful Judith, married Alfrida, the daughter of Alfred the Great. The second Baldwin was renowned chiefly for his work in fortifying the towns of Bruges, Ghent, Ypres and Courtrai as a means of protection against the robber chiefs who still--despite the energetic warfare of his father--infested this entire region. The necessity for protection against robbers, and occasional incursions of savage Danes from the North Sea, caused population to flock speedily into these walled towns, and thus laid the foundation for the wonderful civic development of the next four centuries. The son of Baldwin II, Arnulph--often called Arnulph the Great--continued the policy of strengthening the cities, and also established or restored nearly a score of monasteries and convents for the protection of men and women against the many dangers of that lawless age. The famous chapter of St. Donatian's at Bruges was one of these, and while the Béguinage dates from a somewhat later epoch in the town's history, it admirably exemplifies many of the principles that made these early religious orders the strongholds, not only of piety in a period of semi-barbarism, but of learning and civilisation.
