Left-wing populism is a political ideology which combines left-wing politics and populist rhetoric and themes. The rhetoric often consists of anti-elitist sentiments, opposition to the system and speaking for the "common people". Usually the important themes for left-wing populists include anti-capitalism, social justice, pacifism and anti-globalization, whereas class society ideology or socialist theory is not as important as it is to traditional left-wing parties. The criticism of capitalism and globalization is linked to anti-Americanism which has increased in the left populist movements as a result of unpopular US military operations, especially those in the Middle East.
