paragraph_text: Old Republican period
  
  By the time Brazil became a republic on 15 November 1889, coffee exports were still an important part of São Paulo's economy. São Paulo grew strong in the national political scene, taking turns with the also rich state of Minas Gerais in electing Brazilian presidents, an alliance that became known as " coffee and milk ", given that Minas Gerais was famous for its dairy production. During this period, São Paulo went from regional center to national metropolis, becoming industrialized and reaching its first million inhabitants in 1928. Its greatest growth in this period was relative in the 1890s when it doubled its population. The height of the coffee period is represented by the construction of the second Luz Station (the present building) at the end of the 19th century and by the Paulista Avenue in 1900, where they built many mansions.
  
  Industrialization was the economic cycle that followed the coffee plantation model. By the hands of some industrious families, including many immigrants of Italian and Jewish origin, factories began to arise and São Paulo became known for its smoky, foggy air. The cultural scene followed modernist and naturalist tendencies in fashion at the beginning of the 20th century. Some examples of notable modernist artists are poets Mário de Andrade and Oswald de Andrade, artists Anita Malfatti, Tarsila do Amaral and Lasar Segall, and sculptor Victor Brecheret. The Modern Art Week of 1922 that took place at the Theatro Municipal was an event marked by avant-garde ideas and works of art. In 1929, São Paulo won its first skyscraper, the Martinelli Building.
  
  The modifications made in the city by Antônio da Silva Prado, Baron of Duprat and Washington Luís, who governed from 1899 to 1919, contributed to the climate development of the city; some scholars consider that the entire city was demolished and rebuilt at that time. São Paulo's main economic activities derive from the services industry – factories are since long gone, and in came financial services institutions, law firms, consulting firms. Old factory buildings and warehouses still dot the landscape in neighborhoods such as Barra Funda and Brás. Some cities around São Paulo, such as Diadema, São Bernardo do Campo, Santo André, and Cubatão are still heavily industrialized to the present day, with factories producing from cosmetics to chemicals to automobiles.
  
  In 1924 the city was the stage of the São Paulo Revolt, an armed conflict fought in working-class neighborhoods near the center of São Paulo that lasted 23 days, from 5 to 28 July, leaving hundreds dead and thousands injured. The confrontation between the federal troops of president Artur Bernardes against rebels of the Brazilian Army and the Public Force of São Paulo was classified by the federal government as a conspiracy, a mutiny and a "revolt against the Fatherland, without foundation, headed by disorderly members of the Brazilian Army". To face the rebels, the federal government launched an indiscriminate artillery bombardment against the city, which affected mostly civilian targets; as a result of the bombing, a third of São Paulo's 700,000 inhabitants fled the city. The revolt has been described as "the largest urban conflict in the history of Brazil".
