ABBA
Swedish pop quartet

ABBA ( AB-ə, Swedish: [ˈâbːa]) were a Swedish pop music group formed in Stockholm in 1972 by Agnetha Fältskog, Björn Ulvaeus, Benny Andersson and Anni-Frid Lyngstad. They are among the most renowned and commercially successful musical groups in history.
In 1974, ABBA won the Eurovision Song Contest for Sweden with their song "Waterloo", which was chosen as the best song in the competition's history during its 50th anniversary celebration in 2005. During their peak, ABBA comprised two married couples: Fältskog and Ulvaeus, and Lyngstad and Andersson. As their fame grew, their personal lives suffered, leading to the dissolution of both marriages. These relationship changes were reflected in the group's later music, which featured darker and more introspective lyrics.
After ABBA disbanded in December 1982, Andersson and Ulvaeus continued their success writing music for stage, musicals and films, while Fältskog and Lyngstad pursued solo careers. Ten years after the group's breakup, the compilation ABBA Gold was released and became a worldwide best-seller. In 1999, ABBA's music was adapted into Mamma Mia!, a stage musical that toured globally. As of October 2024, it remains one of the ten longest-running productions on Broadway (closed in 2015) and the West End (still running).

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q18233. VIAF identifies the subject as 312765907. The Library of Congress control number is n78090836. 2 of 7 selected statements include explicit references; 4 carry qualifiers and 0 use preferred rank.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
