During the Old Republic (1889–1930), the "coffee with milk policy" was enforced, which was supported by politicians in São Paulo and Minas Gerais. They alternated in the presidency but were not necessarily Paulistas or Mineiros or their nominees. However, in early 1929, Washington Luís indicated Júlio Prestes to be his successor in a move to be supported by presidents of 17 states. Only three states denied supporting Prestes: Minas Gerais, Rio Grande do Sul, and Paraíba. Politicians from Minas Gerais expected Antonio Carlos Ribeiro de Andrada, then the governor of the state, to be named by Washington Luís as presidential candidate.

An enormous surplus of wheat from 1928 drives down wheat prices, straining commodity markets and farmers' incomes. Unemployment hovers around a robust 4%. US nominal GDP is $105 billion.

The moderate political parties were increasingly unable to stem the tide of extremism, and the German referendum of 1929 helped to elevate Nazi ideology.
Violently thrown out of his paternal home on 28 December 1929. Dalí's relationship with his father was close to rupture. Don Salvador Dalí y Cusi strongly disapproved of his son's romance with Gala, and saw his connection to the Surrealists as a bad influence on his morals. The final straw was when Don Salvador read in a Barcelona newspaper that his son had recently exhibited in Paris a drawing of the Sacred Heart of Jesus Christ, with a provocative inscription: "Sometimes, I spit for fun on my mother's portrait". Outraged, Don Salvador demanded that his son recant publicly. Dalí refused, perhaps out of fear of expulsion from the Surrealist group, and was violently thrown out of his paternal home on 28 December 1929. His father told him that he would be disinherited and that he should never set foot in Cadaqués again.
