[1] The elite agriculturists of Grão-Pará, while living much better, resented their lack of participation in the central government's decision-making, which was dominated by the provinces of the Southeast and Northeast.

Once the fight for independence ended and a provincial government named by the Brazilian Emperor was installed, the local leaders were marginalized from power.

In July 1831 – a few months after the abdication of Emperor Pedro I of Brazil at Rio de Janeiro – a rebellion in the military garrison of Belém do Pará broke out, and Batista Campos was imprisoned as one of the implicated leaders.

The provincial president, Bernardo Lobo de Souza [pt], unleashed a repressive political wave, in an attempt to contain the separatists.

The climax was reached in 1834, when Batista Campos published a letter from the Bishop of Pará, Romualdo de Sousa Coelho [pt], criticizing various politicians from the province.

[5] On the night of January 6, 1835, the rebels attacked and conquered the city of Belém, assassinating president Lobo and the Army Commander, and acquiring a large quantity of munitions.

If it were not for the intervention of his brother Antônio, he would have yielded the government to imperial control, in the person of marshall Manuel Jorge Rodrigues in July 1835.

Naval forces under the command of John Pascoe Grenfell blockaded Belém and, on May 10, Angelim fled from the capital, and was captured and detained.
