On 6 September 1853, Carneiro Leão was appointed President of the Council of Ministers and charged with organizing a new cabinet.[53] Emperor Pedro II wished to advance an ambitious plan, which became known as "the Conciliation".[54] The goal of the Conciliation was to put an end to the periodic eruption of armed conflicts between political factions, such as had occurred in the Praieira rebellion. It had become usual for parties which had lost power in elections to seize back control using force. The Conciliation aimed to strengthen the role of parliament in settling the country's political disputes.
