It was made an free imperial city by the Holy Roman Emperor Frederick II in 1218 after Berthold died without an heir.In 1353 Berne joined the Swiss confederation. After several successful conquers, Berne became the largest independent city state north of the alps. It was occupied by French troops in 1798 during the French Revolutionary Wars, and was stripped of most of its territories. The city became the Swiss capital in 1848. http://wikitravel.org/en/Berne
