2011 Spanish general election

The 2011 Spanish general election was held on Sunday, 20 November 2011, to elect the 10th Cortes Generales of the Kingdom of Spain. All 350 seats in the Congress of Deputies were up for election, as well as 208 of 266 seats in the Senate. An election had not been due until April 2012 at latest, but a call by Prime Minister José Luis Rodríguez Zapatero for a snap election five months ahead of schedule was announced on 29 July 2011. Zapatero would not be seeking a third term in office, and with political pressure mounting, a deteriorating economic situation and his political project exhausted, an early election was perceived as the only way out.

The election campaign was dominated by the effects of an ongoing financial crisis, high unemployment, a large public deficit and a soaring risk premium. Opinion polls had shown consistent leads for the opposition People's Party (PP) over the ruling Spanish Socialist Workers' Party (PSOE), whose popularity had plummeted after Zapatero's U-turns in economic policy had forced him to adopt tough spending cuts and austerity measures. Massive anti-austerity protests had taken place in May 2011 under the form of the 15-M Movement, and in the local and regional elections held a few days later popular support for the PSOE fell dramatically. On 21 October, the armed organization ETA announced a permanent cessation of armed activity, turning the 2011 election into the first since the Spanish transition to democracy without ETA attacks.

The election resulted in the PSOE being swept out from power in the worst defeat for a sitting government in Spain up until that time since 1982, losing 4.3 million votes and scoring its worst result in a general election ever since the first democratic election in 1977. In contrast, PP's Mariano Rajoy won a record absolute majority in a landslide, being his party's best historic result as well as the second largest and, to date, last majority in Spanish democracy. Also for the first time in a general election, the PSOE failed to come out on top in both Andalusia and Catalonia, with the nationalist Convergence and Union (CiU) emerging victorious in the later, whereas the abertzale left Amaiur achieved a major breakthrough in both the Basque Country and Navarre. United Left (IU) experienced a turnaround of its electoral fortunes and saw its first remarkable increase in 15 years, whereas centrist Union, Progress and Democracy (UPyD) exceeded all expectations with over one million votes, 5 seats and just 0.3% short of the 5% threshold required for being recognized a party parliamentary group in Congress.
