Changes
===XX Century===
By the 1920s, the emerging middle and working classes were powerful enough to elect a reformist president, whose program was frustrated by a conservative congress. In the 1920s, Marxist groups with strong popular support arose.
Continuing political and economic instability resulted with the rule of the quasidictatorial Gen. Carlos Ibáñez (1924–32). In June there was a Coup and between that month and September of 1932 there was an attempt to establish a [[Socialist]] Republic that failed.When constitutional rule was restored in 1932, a strong middle-class party, the Radicals, emerged. It became the key force in coalition governments for the next 20 years. During the period of Radical Party dominance (1932–52), the state increased its role in the economy.
In 1940 Chile started to claim officially the [[Chilean Antarctic Territory]].
