 of Prussia also acknowledged his authority, and a peace was made at Dresden in 1745.

From the year 1745 to 1756 the land had peace, so that it was enabled, to some extent, to recuperate the strength wasted in so many wars; but in 1756 another war broke out, which is known in history as the Seven Years’ War.

Maria Theresa never became fully reconciled to the loss of beautiful Silesia, and was only waiting for a favorable opportunity to try to regain it. Such a moment seemed to have arrived in the year 1756, when, having gained France as an ally, she declared war against Frederick.

At the very beginning of the war, Frederick invaded Bohemia, and, after gaining a brilliant victory at Lovosic, he marched to Prague, where Charles of Lorraine was waiting to receive him. A battle was fought, where Frederick gained another victory, compelling Charles to shut himself up in Prague, where he was besieged by the Prussians for six weeks. The enemy, trying to force him to surrender, kept up a constant bombardment upon the city, sadly damaging some of the finest buildings, among these the cathedral on the Hradschin. Finally, the Field Marshal Daun coming to the assistance of the distressed city, Frederick raised the siege, and went to meet the coming army. A decisive action took place at Kolin. Frederick was defeated, and compelled to leave the country in the wildest disorder, having lost 20,000 men.

From that time on, the war was carried on outside of Bohemia, mostly in the dominions of Frederick.
