While Brazil paid superior value for the importation, being obliged to appeal frequent loans, establishing economic dependence in relation to England. In this direction, Brazil did not continue dependent moving only of owner, being now English colony? An independent time, Brazil needed to create its Imperial State with its proper laws, powers and governing. With the French Revolution, a iluminista idea appears of that all the countries must have constitutions, that is, a document species, a contract between government and citizen. For creation of the Brazilian constitution of the Imperial State, a Constitutional conventional was elect, that if congregated in 1823 composed for ninety pertaining members of the house of representatives the aristocracy (great land proprietors, members of the Church, jurists) being this an indirect election. In the same year, a Project of Constitution for the member of the house of representatives was presented Antonio Carlos de Andrada, brother of Jose Bonifcio for quarrel between the members of the house of representatives, that detached two basic principles: the first one mentions it subordination of the Executive to the Legislative one, that is, the State would have to be controlled for the proper agricultural aristocracy. This test that the emperor could not dissolve the House of representatives and that the Armed Forces would be submitted to the Legislative one, not to the emperor.

As the principle foca the restriction of access to the life national politics of the majority of the Brazilian population, for the tax criterion, established for the elections. In other words, the voter or the candidate to the Legislative one would have to possess high incomes, obtained especially of agricultural activities. Being the incomes of the voters and candidates calculated for the total of its annual production, that would have to be equivalent to the production of alqueires of cassava. For this reason she was known as Constitution of the Cassava.
