By relinquishing power to a democratically elected successor, Ibáñez del Campo retained the respect of a large enough segment of the population to remain a viable politician for more than thirty years, in spite of the vague and shifting nature of his ideology. 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 1952, voters returned Ibáñez del Campo to office for another six years. Jorge Alessandri succeeded Ibáñez del Campo in 1958, bringing Chilean conservatism back into power democratically for another term.
