Erlander Cabinet I 1946–1951
Tage Erlander's first cabinet — a Social Democratic single-party minority that took office on Per Albin Hansson's sudden death in October 1946, inherited the Hansson IV ministerial roster, passed the foundational 1947 folkpension and barnbidrag laws, weathered a 1947 currency crisis and Gunnar Myrdal's resignation, and dissolved itself in October 1951 to form the red-green coalition with Bondeförbundet.
The Erlander I cabinet took office on 11 October 1946, five days after Per Albin Hansson collapsed and died at a Stockholm tram stop. Foreign Minister Östen Undén served briefly as caretaker until SAP settled on its youngest minister, Tage Erlander, as Hansson’s successor. The new cabinet kept fourteen ministers from Hansson IV and governed as a Social Democratic single-party minority.
The cabinet’s signature legislation came in 1947: a national basic pension (folkpension) and a national child allowance (barnbidrag), the foundational statutes of post-war Folkhemmet expansion. The same year, a 17 percent appreciation of the krona triggered a trade-deficit crisis and forced Minister of Commerce Gunnar Myrdal — the first member of the Erlander cabinet to resign — out of office. The 1948 election left SAP at 112 of 230 lower-house seats; Erlander offered a coalition to the Centre Party (then Bondeförbundet), which declined.
Seeking a stable parliamentary majority against a strengthening Liberal–Moderate opposition led by Bertil Ohlin, Erlander dissolved the single-party cabinet on 1 October 1951 and formed the red-green 1951 coalition with Bondeförbundet, opening the 1957 pension-reform fight that would later break that very coalition.
