WORMS, a city of Germany, in the Land of Hesse. It is situated on the left bank of the Rhine, 25 m. S. of Mainz, 20 m. N.W. of Heidelberg and 9 m. by rail N.W. of Mannheim. Pop. 50,473.
Under the German kings the power of the bishops of Worms gradually increased. Otto I. granted extensive lands to the bishop, and in 979 Bishop Hildbold acquired comital rights in his city. Burchard I. (bishop, 1000-25) destroyed the castle of the Fran conian house at Worms, built the cathedral and laid the founda tions of the subsequent territorial power of the see. There were frequent struggles between the bishops and the citizens, who espoused the cause of the emperors against the church, and were rewarded by privileges which fostered trade. The city re tained its freedom until 1801, in spite of the bishops, who ruled a small territory south of the city, on both sides of the Rhine, and resided at Ladenburg near Mannheim till 1622.
The city of Worms was frequently visited by the imperial court. The concordat of Worms closed the investiture contro versy in 1122. The "perpetual peace" (ewiger Landfriede) was proclaimed by the emperor Maximilian I. at the diet of 1495, and Luther appeared before the famous diet of 1521 to defend his doctrines in the presence of Charles V. Four years later, Worms formally embraced Protestantism, and religious conferences were held there in 154o and 1557. It suffered severely during the Thirty Years' War. The French under Melac burnt the city al most entirely in 1689, and it has only fully recovered from this blow in recent years. Thus the population, which in its prosper
ous days is said to have exceeded 5o,000, had sunk in 1815 to 6,25o.
By the treaty of Worms in 1743 an offensive alliance was formed between Great Britain, Austria and Sardinia. The city was annexed to France at the peace of Luneville in 1801, to gether with the bishop's territories on the left bank of the Rhine. The remaining episcopal dominions were secularized in 1803 and given to Hesse-Darmstadt, which acquired the whole by the Vienna Congress in 1815.
The old Bischofshof, in which the most famous Diet of Worms (1521) was held, has been replaced. The Luginsland is an old watch-tower of the 13th century. The Lutherplatz contains a group of statuary commemorating the Protestant reformers and their forerunners. Extensive burial-grounds, ranging in date from neolithic to Merovingian times, have been discovered near the city.
Worms is the centre of a vine-growing country. The manufac tures include patent leather, machinery, cloth, chemicals, paints, cork, furniture, slates, etc. Worms possesses a good river harbour, and carries on a considerable trade by water.
