1901–2000
1901 – National military service is introduced and all men between the ages of 18 and 47 are obliged to do basic military training and refresher training. If they are called up in the event of war or danger of war, they are obliged to report for duty. The system lives on until the middle of the 1990s. From 2010, national military service is replaced with a period of voluntary training.
1917 – A parliamentary system of government is introduced. This means that the Government is accountable to the Riksdag and must have support for its policy. The Riksdag is in turn accountable to its voters, that is the people. The King no longer decides who is to sit in the Government and in practice loses his political power.
1919 - Eight-hour working day is decided on. Since the working week still consists of six days, there are 48 working hours per week.
1918 – 1921 – The Riksdag decides to introduce universal and equal suffrage for both men and women. Both men and women now have one vote each and are eligible for election to the Riksdag. Democracy has now arrived.
1923 – The Eligibility Act is adopted. The Eligibility Act states that women are now entitled to all employment in the public sector except military positions and the priesthood. From 1974 onwards, men and women have equal rights to all kinds of work.
1928 – Act on Collective Agreements is introduced and the Swedish Labour Court is established. This forms the basis for the modern labour market. In practice, the Act only covers employees in industry and transport and does not apply to state employees, servants, commercial employees and agricultural employees.
1946 – Sweden becomes a member of the UN.
1947 – Sweden signs the international free trade agreement GATT. The agreement regulates trade across national borders. Its purpose is to increase international trade by reducing customs duties and other trade barriers.
1950 – Sweden becomes a member of the Council of Europe which promotes democracy, human rights and the rule of law. Sweden signs the European Convention for the Protection of Human Rights and Fundamental Freedoms. However, it is not until 1995 that the Convention becomes part of Swedish law and thus enforceable in practice.
1950 – The Riksdag decides to introduce compulsory nine-year schooling for all children. Now, all pupils have to attend school for at least nine years.
1951 – The Freedom of Religion Act is established. This gives Swedish citizens the right to freely leave the Church of Sweden without joining another approved religious community. The Freedom of Religion Act states that everyone has the right to practise their religion and arrange services in public. Government ministers no longer have to be Christian.
1962 – Common universal compulsory school is introduced. The idea is that all pupils should go to the same sort of school, with the same curriculum. Now, education is the same for everyone.
1971 – The bicameral system is abolished and a unicameral system is introduced. As of now, citizens can determine the composition of the Riksdag in one and the same election. The new electoral system means that the parties receive exactly the same share of seats as they do votes. This is acknowledged in the 1974 Riksdag Act.
1974 – a new Instrument of Government was introduced in which the parliamentary system of government is stated as part of the Constitution. The King’s political power, which has already been abolished in practice, now also formally disappears.
1994 – The electoral period for the Riksdag, the County and Municipal Councils was extended from three to four years.
1995 – Sweden becomes a member of the European Union (EU). Sweden's electorate are now able to vote in the election to the European Parliament and parts of the Riksdag’s legislative powers are transferred to the EU.
