Historical overview
Switzerland developed from medieval alliances among Alpine communities into a confederation of cantons and eventually a modern federal state. The Federal Charter of 1291 is traditionally regarded as an important founding document of the Swiss Confederation. However, its interpretation as the definitive founding act became prominent mainly in the nineteenth century.
During the late medieval and early modern periods, the Confederation expanded through alliances among different cantons. The Reformation created religious divisions, and disputes between Catholic and Protestant cantons repeatedly influenced political relations.
In 1798, French forces invaded Switzerland and established the Helvetic Republic, a centralised state that replaced the old confederal system. The Act of Mediation in 1803 restored a more decentralised structure. Following the defeat of Napoleon, the Congress of Vienna recognised Swiss neutrality and established the Federal Treaty of 1815.
Conflict between liberal and conservative Catholic cantons culminated in the Sonderbund War of 1847. The liberal cantons won, creating the political conditions for a new federal constitution. The Federal Constitution adopted in 1848 established the modern Swiss federal state, with a Federal Assembly, Federal Council and Federal Court. admin.chThe 1874 constitutional revision expanded federal powers and introduced the optional federal referendum. In 1891, citizens gained the right to initiate constitutional amendments through popular initiatives. These reforms became central elements of Switzerland’s system of direct democracy.
However, the expansion of political rights was unequal. Women were excluded from national voting until 1971, when male voters approved women’s suffrage at the federal level. Some cantons introduced women’s voting rights earlier, while the last canton to grant women equal voting rights at the cantonal level was Appenzell Innerrhoden in 1990, following a Federal Supreme Court decision.
Switzerland maintained armed neutrality during both World Wars. Its wartime policies, financial relationships, refugee admission decisions and economic connections with Nazi Germany have since been the subject of extensive historical investigation. The Bergier Commission, formally the Independent Commission of Experts Switzerland–Second World War, examined these issues in the 1990s and early 2000s.
The 1999 Federal Constitution, which entered into force on 1 January 2000, reorganised and updated the constitutional framework while retaining the basic federal and direct-democratic system.

Editorial note: Switzerland’s direct democracy should not be confused with universal participation throughout its history. National women’s suffrage arrived only in 1971, and some cantonal restrictions lasted until 1990. Include the history of political exclusion, religious conflict, migration, refugee policy and the country’s relationship with Nazi Germany during the Second World War.
