granting more autonomy to the provinces it could placate discontent and extinguish any separatist threat. A constitutional amendment effecting greater decentralization was voted upon and approved in the Chambers of Deputies, but it still faced major opposition in the Senate. The priest Antônio Feijó planned a coup d’état in which he would assume dictatorial powers and the constitutional amendment would be enacted concurrently without the approval of the National Assembly (Parliament). On 30 July 1832 some Nativist deputies (in concert with Feijó) put a proposal before the Chamber that parliament be turned into a constituent assembly and that a new constitution be adopted using as part of their argument that the senate was filled with restorationist senators. The Deputy Carneiro Leão managed to successfully rally the other deputies against the Nativists' proposal and the coup attempt was crushed. The Coimbra bloc's firm actions prevented restriction of legal rights and kept Brazil from sliding into dictatorship during the regency even under the threat of rebellions and political crises. The Additional Act and resulting rebellions The constitutional amendment, called the Ato Adicional (Additional Act), was finally promulgated on 12 August 1834. Among its provisions was the establishment of a quasi-federal national structure due to administrative and political provincial decentralization. "Dissolution of power to the provinces, far from placating local ambitions and discontents, kindled them into flame. In the far north and the far south, civil wars broke out." The higher administrative and political provincial decentralization exacerbated conflicts between political parties, as whichever dominated the provinces would also gain control over the electoral and political system. Those parties which lost elections rebelled and tried to assume power by force. Rebellious factions, however, continued to uphold the Throne as a way of giving the appearance of legitimacy to their actions (that is, they were not in revolt against the monarchy per se). The Cabanagem (1835–40), the Sabinada (1837–38) and the Balaiada (1838–41) all followed this course, even though in some instances provinces attempted to secede and become independent republics (though ostensibly only so long as Pedro II was a minor). The exception was the Ragamuffin War, which began as yet another dispute between political factions in the province of Rio Grande do Sul but quickly evolved into a separatist rebellion financed by the Argentine dictator Don Manuel Rosas. But even in this case, the majority of the province's population, including the largest and most
