Troyes, a city of France, capital of the department of Aube, and formerly of Champagne, on the left bank of the Seine, 90 m. E. S. E. of Paris; pop. in 1872, 38,113. It has a cathedral with a celebrated choir and stained glass windows, and surrounded by five chapels, begun about 1200 and finished in the 16th century, and recently restored. The unfinished collegiate church of St. Urban, and those of St. John, St. Nizier, and the Madeleine, are likewise remarkable. The lyceum of Troyes is one of the finest in France. In the former abbey of St. Loup is an extensive collection of books and manuscripts. The museum is rich in coins and mosaics. The manufactures of cotton and woollen goods and hosiery are of great extent. Soap, sausages, and cheese are also made. - Troyes was originally the capital of the Tricasses. Under the Romans it was included in Gallia Lugdunensis, and became known as Augustobona, and in the 5th century as Trecae. At the close of the 9th century it was devastated by the Normans. It was the seat of several councils, and under the counts of Champagne it rose in the 12th century to great importance.

John the Fearless of Burgundy captured the town in 1415. The treaty uniting the French and English crowns, concluded here May 21, 1420, was sealed on June 2 by the marriage of Henry V. with the princess Catharine. During the war between Charles V. and Francis I. it was almost reduced to ashes by the former (May, 1524). In 1814 it was a prominent battle ground between Napoleon and the allies. In November, 1870, it was occupied by the Germans.
