For over 50 years, Sweden had had five parties who continually received enough votes to gain seats in the Riksdag—the Social Democrats, the Moderate Party, the Centre Party, the Liberal People's Party and the Left Party—before the Green Party became the sixth party in the 1988 election. In the 1991 election, while the Greens lost their seats, two new parties gained seats for the first time: the Christian Democrats and New Democracy. The 1994 election saw the return of the Greens and the demise of New Democracy. It was not until elections in 2010 that an eighth party, the Sweden Democrats, gained Riksdag seats. In the elections to the European Parliament, parties who have failed to pass the Riksdag threshold have managed to gain representation at that venue: the June List (2004–2009), the Pirate Party (2009–2014), and Feminist Initiative (2014–2019).
