CENTURY XI.
The Prussians, during this century, were driven into the fold of the Church. A Christian missionary, Adalbert, bishop of Prague, had been murdered by the “fierce and savage Prussians,” and in order to show the civilising results of the gentle Christian creed, Boleslaus, king of Poland, entered “into a bloody war with the Prussians, and he obtained, by the force of penal laws and of a victorious, army, what Adalbert could not effect by exhortation and argument.
