Part of the Helvetic Republic after 1798, it became in 1803 one of the 19 cantons of the Swiss Confederation as reconstituted by Napoleon’s Act of Mediation. Although distinctly Roman Catholic, it did not join the Sonderbund (separatist league of Catholic cantons) in 1845, and it approved the federal constitutions of 1848 and 1874. The present cantonal constitution dates from 1887 but was substantially revised in 1895.

Until the 19th century, the canton’s economic activities were mainly agricultural and pastoral. Although these are still important, the population is largely engaged in the manufacture of a variety of goods, including watches, jewelry, shoes, cotton textiles, paper, cellulose, cement, auto parts, iron and steel products, and electrical-communications equipment. A nuclear-power station began operation at Gösgen in 1979. The canton has excellent road and rail connections. Olten is a railway junction for direct lines from Geneva, Zürich, and Basel and the St. Gotthard Pass via Lucerne. The population is almost entirely German-speaking, with three-fifths Roman Catholics and two-fifths Protestants. Area 305 square miles (791 square km).

Solothurn is regarded as the finest Baroque town in Switzerland, where Italian grandeur is combined with French charm and German practicality. The so-called “ambassador’s town” is at the southern end of the Jura by the River Aare, about 30 km west of Biel/Bienne.

From the 16th to the 18th centuries, the Catholic town of Solothurn was the residence of the French king’s ambassador. Fine Baroque and Renaissance buildings, such as the noble Palais Besenval, and magnificent religious buildings meet the visitor at every end and turn – the Old Town has eleven churches and chapels and the same number of fountains and towers. Truly magnificent is the St.Urs Cathedral, with a façade donated by Louis XIV, and an Italian-style staircase in front. Inside are wonderful Baroque stuccos. The town walls, which are still intact in some places, were built according to the principles of the French military engineer Vauban.
