erected in 1993 to commemorate the Council.
In 1460 the Swiss Confederacy conquered Thurgau, Konstanz's natural hinterland. Konstanz then made an attempt to get admitted to the Swiss Confederacy, but the forest cantons voted against its entry, fearing over-bearing city states; Konstanz then joined the Swabian League instead. In the Swabian War of 1499, Konstanz lost its last privileges over Thurgau to the Confederation.
The Protestant Reformation took hold in Konstanz in the 1520s, headed by Ambrosius Blarer. Soon the city declared itself officially Protestant, pictures were removed from the churches, and the bishop temporarily moved to Meersburg, a small town across the lake. The city first followed the Tetrapolitan Confession, and then the Augsburg Confession. However, in 1548 Emperor Charles V imposed the Imperial Ban on Konstanz and it had to surrender to Habsburg Austria which had suddenly attacked. Thus Konstanz lost its status as an imperial city. The new Habsburg rulers were eager to re-Catholicise the town and in 1604 a Jesuit College was opened. Its accompanying theatre, built in 1610, is the oldest theatre in Germany still performing regularly.
The city became part of the Grand Duchy of Baden in 1806. In 1821, the Bishopric of Constance was dissolved and became part of the Archdiocese of Freiburg. Konstanz became part of the German Empire in 1871 during the unification of Germany. After World War I it was included within the Republic of Baden.
Because it almost lies within Switzerland, directly adjacent to the Swiss border, Konstanz was not bombed by the Allied Forces during World War II. The city left all its lights on at night, and thus fooled the bombers into thinking it was actually part of Switzerland. After the war, Konstanz was included first in South Baden and then in the new state of Baden-W�rttemberg
