State deputy (1919–1921) Francisco Campos began his political career in 1919 after being included by Raul Soares, then Minas Gerais' Secretary of the Interior, in the
Republican Party of Minas Gerais' (PRM) list of candidates for
state deputy for the 1919–1922 legislature. Campos was elected in 1919 with 4,287 votes in the 7th Electoral District. The year before,
Artur Bernardes had taken took office as president (
governor) of Minas Gerais. Bernardes and Raul Soares introduced changes to Minas Gerais' political landscape, consolidating the hegemony of representatives from the
Zona da Mata in the state's politics and dismantled the influence of former state president Francisco Sales within the state apparatus and the PRM, which was the sole political party in the state. As state deputy, Campos played a prominent role in the constitutional reform initiated by Bernardes. Campos also opposed municipal autonomy, as he viewed the
municipalities as executive bodies with a purely administrative function, subject to appointment or designation by the state government. In 1920 he declared that "Municipal governments are nothing more than a modality—indeed, the most effective and intelligent one—of central administration's control over local administration"
. Federal deputy (1921–1926) Campos resigned his position as state deputy after being elected
federal deputy for Minas Gerais, taking office in April 1921. As federal deputy, Campos became a staunch critic of liberalism and liberal institutions. In 1921 he declared that "The era of liberty as a natural right, superior to and preceding the organic formation of society, is over. Both right and liberty are merely forms and modalities of social existence, or organs designed for specific social functions. In the modern regime, individual freedoms have come to be guaranteed by the State, and State administration has become a legal administration".
