The zealous bishop, perhaps not unwilling to secure the crown of martyrdom, pressed on, preaching the Gospel, in face of prohibitions and menaces, until he entered one of the sacred inclosures which was a sanctuary of the idols of these heathen. The priests rushed upon him, endeavored to drive him out, and struck him with a dagger in the back of his neck. He uttered but one cry, “Jesus, receive me!” and, stretching out his arms, fell with his face to the ground, and lay dead there “in the form of a crucifix.” The place is yet pointed out where Adalbert fell. Still the seeds of Christianity were sown. Other missionaries followed. Idolatry disappeared, and the realm became nominally Christian. Revealed religion introduced increased enlightenment and culture, though there still remained much of the savagery of ancient days. When the Reformation in the sixteenth century was presented to Europe, and was rejected by Italy, France, Austria, and Spain, it was accepted, though not unanimously, yet very generally, by the inhabitants of this wild region. In the year 1700 there was, in the midst of the realm of which we are about to write, and which is now called Prussia, a province then known as the Marquisate of Brandenburg. It embraced a little over fifteen thousand square miles, being about twice as large as the State of Massachusetts. It was one of the electorates of Germany, and the elector or marquis, Frederick, belonged to the renowned family of Hohenzollern. To the east of Brandenburg there was a duchy called Prussia. This duchy, in some of the political agitations of the times, had been transferred to the Marquis of Brandenburg. The Elector of Brandenburg, Frederick, an ambitious man, rejoicing in the extent of his domain, which was large for a marquisate, though small for a monarchy, obtained from the Emperor of Germany its recognition as a kingdom, and assumed the title of Frederick I. of Prussia. Many of the proud monarchies of Europe did not conceal the contempt with which they regarded this petty kingdom. They received the elector into their society very much as haughty nobles, proud of a long line of illustrious ancestry, would receive a successful merchant who had purchased a title. Frederick himself was greatly elated with the honor he had attained, and his subjects shared with him in his exultation. [Illustration: FREDERICK THE GREAT.]
