1948 Second-Chamber Election and Liberal Rise

In September 1948 Sweden held its first general election under Tage Erlander, who had inherited the premiership after Per Albin Hansson’s sudden death in October 1946. SAP won 46.13 % and 112 of 230 Second-Chamber seats — a small retreat from 1944 but enough to keep governing. Folkpartiet under Bertil Ohlin surged to roughly 22.8 %, leapfrogging the Right and becoming the principal non-socialist opposition.

The election opened what is widely treated as the most consequential party-leader rivalry in modern Swedish politics: Erlander’s strong-society social democracy against Ohlin’s market-liberal welfare programme. The argument over the shape of post-war welfare — universal-and-mandatory or means-tested-and-voluntary — runs straight from 1948 through the 1957 pension referendum to the 1959 ATP fight.

It was also the first electoral verdict on the 1947 welfare package. Voters did not punish the universal child allowance or the basic-pension reform; they punished, modestly, the post-war inflation and rationing — but kept SAP in government. That signal — that universalism could be politically rewarded — set the strategic baseline for the next two decades.
