A populist governor of Brazil's southernmost Rio Grande do Sul state, Vargas was a cattle rancher with a doctorate in law and the 1930 presidential candidate of the Liberal Alliance. Vargas was a member of the gaucho-landed oligarchy and had risen through the system of patronage and clientelism, but had a fresh vision of how Brazilian politics could be shaped to support national development. He came from a region with a positivist and populist tradition, and was an economic nationalist who favored industrial development and liberal reforms. Vargas built up political networks, and was attuned to the interests of the rising urban classes. In his early years Vargas even relied on the support of the "tenentes" of the 1922 rebellion.
