The Swedish Social Democratic Party has held power in Sweden most years for a whole century. For many years, it held it in coalition with other left-wing parties, proposing the general course of democratic functional socialist ideology, regular measures to strengthen the welfare state, a benevolent immigration policy, and a peaceful foreign policy, by mediating between west and east, and also north and south. Social Democrat activities were often carried out clearly and with predictability, with great hopes of counteracting future economic, social, political and cultural challenges. When too many of these challenges appeared in public and foreign policy, the ‘social democratic arsenal’ vanished, and less preventive measures appeared to counteract the cataclysms. The radical Sweden Democrats Party rushed into the political arena, and became the third party after the 2018 Riksdag election, and the second party after the 2022 Riksdag election. The Sweden Democrats proposed not only widening and deepening the welfare state’s programmes, and strengthening punishments for crime, but also a strict anti-immigration policy, primarily a racist anti-immigration policy towards newcomers from the Middle East and Africa. Other right-wing parties viewed the programme and the activities of the Sweden Democrats with reservation, but they had to form a coalition with four right-wing parties in order to win the Riksdag elections. After a right-wing victory in the 2022 election, Ulf Kristersson, the leader of the Moderates, attained the right to form a government on behalf of a coalition between the Moderates, the Sweden Democrats, the Christian Democrats and the Liberals. The political situation in Sweden before and after the 2018 and 2022 Riksdag elections is presented in the article, together with the political crisis between these two elections, as well as the results of the 2018 and 2022 elections. In the article, the author uses the descriptive analytical method, together with synthesis and some evaluations of the Riksdag elections.
