1994 EU Membership Referendum
On 13 November 1994 a Swedish referendum on European Union membership returned 52.74 percent Yes against 47.26 percent No on a record 83.32 percent turnout. SAP, M, FP, C and KD backed Yes; the Left Party and Miljöpartiet opposed. The vote authorised accession on 1 January 1995 and confirmed the abandonment of Cold-War-era non-alignment.
The 13 November 1994 EU membership referendum was Sweden’s first foreign-policy referendum since the 1980 nuclear-power vote and the first ever to bind the country into a supranational legal order. On a record 83.32 percent turnout the Yes side won with 52.74 percent (2,833,721 votes) against the No side’s 47.26 percent (2,539,132).
The referendum was called by the incoming Carlsson III cabinet but executed on accession terms negotiated by the outgoing Bildt cabinet and signed at Corfu on 24 June 1994. SAP, M, FP, Centerpartiet and KD supported Yes; the Left Party (V) and Miljöpartiet opposed.
The narrow margin defined two decades of EU-policy contestation inside SAP and on the centre-left, resurfacing at the 2003 euro referendum and again in debates about the folkhemmet tradition’s compatibility with European integration. The procedural template — referendum on every major sovereignty pooling — became Swedish constitutional practice and informed later debates on the euro and on NATO.
