[1][2] The 1937 Constitution satisfied the interests of political groups who wanted a strong government that would benefit the dominant parties and consolidate the rule of those on Vargas' side.

In November 1935, the ANL organized a revolt, with uprisings in Rio de Janeiro and Natal, when military officers were coldly murdered while they slept in their barracks.

[8][9][10] Fifty days later, with the support of the integralists, the conservative military, the industrial bourgeoisie and intervenors from various states, Vargas ordered the police to surround the Chamber of Deputies, imposed a recess on the legislature and granted the new constitution.

[11] The 1937 Constitution was drafted and written mostly by Francisco Campos (who would later prepare the institutional acts of the 1964 military dictatorship), with the assistance of integralist leaders, a year before the coup.

[2] According to Paulo Bonavides in his work Curso de Direito Constitucional, the document:[...] represents in the context of constitutionalism a broad outline of the limitation of the authority of the ruler.

The king, prince or head of state wields absolute powers in his hands, but unilaterally consents to divest himself of a portion of his unlimited prerogatives, for the benefit of the people, who enjoy rights and guarantees, both legal and political, apparently by the sole work and grace of royal munificence.

[2][16] The text maintained some of the characteristics of previous statutes, such as the tripartite division of powers, the "presence" of the Federal District in direct administration and the laicity of the country.
