Ravensburg is a town in Upper Swabia in Southern Germany, capital of the district of Ravensburg, Baden-Württemberg.

Ravensburg was first mentioned in 1088. In the Middle Ages, it was an Imperial Free City and an important trading centre. The "Great Ravensburg Trading Society" owned shops and trading companies all over Europe.

The historic town centre is still very much intact, including three town gates and over 10 towers of the medieval fortification. "The all-white Mehlsack (Flour Sacks) is a tower marking the Altstadt's southern edge. A steep staircase leads up to the Veitsburg, a quaint baroque castle."

The town's most popular festival is the annual "Rutenfest", which takes place mid year.

Ravensburg was first mentioned in writing in 1088. It was founded by the Welfs, a Frankish dynasty in Swabia who became later Dukes of Bavaria and Saxony and who made the castle of Ravensburg their ancestral seat.

By a contract of inheritance, in 1191 the Hohenstaufen Frederick Barbarossa acquired the ownership of Ravensburg from Welf VI, Duke of Spoleto and uncle of both Frederick Barbarossa and Henry the Lion.

With the death of Conradin 1268 in Naples the Hohenstaufen line became extinct. Their former estates became imperial property of the Holy Roman Empire. Like many other cities in Swabia, at the end of the 13th century Ravensburg became an Imperial Free City in 1276.

The "Great Ravensburg Trading Society" was founded at Ravensburg and Konstanz around 1380 by the merchant families of Humpis (from Ravensburg), Mötteli (from Buchhorn, modern-day Friedrichshafen) and Muntprat (from Constance). At first, the society mostly dealt in the production of linen and fustian. With the opening of one of the first paper mills north of the Alps in 1402 in Ravensburg, paper became another commodity. The Ravensburg stores also sold oriental spices, Mediterranean wines and Bohemian ores. After the liquidation of the Great Ravensburg Trading Society in 1530, Ravensburg stagnated economically. The Thirty Years' War caused a grave decline of the population. Swedish troops destroyed the old castle, now named "Veitsburg" after the St. Veit chapel at the castle grounds.

Following the Reformation a "paritetic" government emerged, meaning an equal distribution of public offices between the Catholic and Protestant confession. The city council was one half each Protestant and Catholic. For some time there was even a Catholic and a Protestant mayor at the same time, and the both confessions celebrated the village fair, the "Rutenfest", apart from each other. This system was approved at the end of the Thirty Years' War in the Peace of Westphalia (1648).

In 1803 the Immerwahrende Reichstag passed the Reichsdeputationshauptschluss, a bill which included the secularisation and mediatisation of many German states - the first meaning the confiscation of the estates belonging to the church, the second the incorporation of the imperial estates and Imperial Free Cities into larger regional states. As a result, Ravensburg first became a Bavarian exclave within Württemberg. After a swap of estates between Bavaria and Württemberg it was incorporated in the Kingdom of Württemberg in 1810.

Since Ravensburg was impoverished and depopulated after the Thirty Years' War, only a few new buildings were raised during the 18th and the early 19th century. The benefit of this economic stagnation was the conservation of a widely intact medieval city with nearly all towers and gates of the historic fortification.
