The regency was due to Dom Pedro I's decision to abdicate the throne because of the dissolving relations between the Emperor and the assembly, a failed war with Argentina, and a mounting constitutional crisis.

[1] Immediately following the enactment of these laws, Pedro II and the cabinet appointed loyalists as political agents, chiefs of police and judges in the provinces that would soon rebel.

[1] Unrest in the provinces of Maranhão (Balaiada) and Rio Grande do Sul (Ragamuffin War) had not been fully resolved, when, in 1840, the young emperor Pedro II assumed the throne.

[4] The members of the Ministry also feared that Dom Pedro II's efforts would have a negative effect on the economic interests of the larger states.

In an attempt to minimize the influence of the Liberals in São Paulo, the emperor dismissed Tobias de Aguiar and, after the short tenure of Melo Alvim, appointed José da Costa Carvalho to replace Manuel Marques, since Manuel Marques de Sousa, Count of Porto Alegre was a rich farmer who interacted with the Reactionaries.

[5][6] Liberal elites in Minas Gerais, São Paulo, and Rio de Janeiro appointed new provincial presidents and began military resistance.

Two, and more specific to the state of São Paulo, it was a reaction to new laws that modified and regulated the criminal code, and the newly instituted forced adjournment of the House of Deputies.

Rafael Tobias de Aguiar, one of the wealthiest merchants in Brazil and a powerful nativist leader, was sworn to "defend the Emperor and the Constitution until the last drop of his blood.

[7] Under his military command, he established the Liberating Column, with some 1,500 men, to march to São Paulo where they would overthrow the President of the Province, José da Costa Carvalho.

Sorocaba was declared the provisional capital of the province, and was joined by several inland villages such as Itu, Itapeva, Porto Feliz, Itapetininga and Capivari.

[8] He joined forces in Ouro Preto with Luís Alves de Lima e Silva (then-Baron and later Duke of Caxias), who commanded the National Guard of São Paulo and Minas Gerais.

[10] The defeated leaders of the rebellion were captured and then deported to the province of Espírito Santo while their followers and general rebels were pushed into service in the Emperor's army.

Luís Alves de Lima e Silva, commander of the army, employed the same strategy used in São Paulo, taking the capital as quickly as possible, on August 6, 1842.

As Honório Hermeto returned from Minas Gerais to Rio de Janeiro, he was welcomed with celebrations and demonstrations of joy by the authorities and populace of the districts he traversed.

Ultimately, the rebels framed rebellion as a means to protect Dom Pedro II by forcing the resignation of the Cabinet Members and overturning of bad policies.
