The 1930s also saw a change in the role of government. Until then, the state acted primarily in response to the demands of the export sector. During the first half of the decade, it was forced to interfere swiftly in an attempt to control the external crisis and to avoid the collapse of the coffee economy; government leaders hoped that the crisis would pass soon and that another export boom would occur. However, with the magnitude and duration of the crisis it became clear that Brazil could no longer rely solely on exports of primary goods and that it was necessary to promote economic diversification. During the Estado Novo, the government made initial attempts at economic planning, and in the late 1930s began to establish the first large government enterprise, an integrated steel mill, Companhia Siderúrgica Nacional.
