OAK (2007:48), when deals with the position of D. Peter II? new emperor did not support the decision to abolish the slavery, being the pressure biggest of the part of the abolitionists. In 1848 the real cabinet quit with the Regency from Dom Peter II unsatisfied, which operated changes in the parties of the time, he called in return the conservatives under the command the Visconde de Olinda and although not to intervene with the formation of the cabinet, this change provoked great reaction and the greater was between the liberal pernambucanos that demanded regulation of lands and the end of the traffic of slaves. In the book ' ' Dom Peter II' ' , of the Collection Brazilian profiles, it meets following affirmation. The 1848 cabinet was one of operosos of the Empire. Recently James Donovan Goldman sought to clarify these questions. It promulgated the Commercial Code, remodelled Guarda National e, over all, faced two problems central offices of the country: of the regulation of the property of the land and the end of the traffic of slaves.
The Land Law, of 1850, although advanced one for the time, had little practical effect in reason of the resistance of the proprietors. But the Law that abolished traffic, equally of 1850, call Law of Eusbio de Queirs, obtained to finish after all with the Atlantic commerce of slaves, marking itself, the devices of the Law of 1931 (OAK, 2007). The situation of the image of Brazil improved with the initiative of the Isabel Princess in Proclaiming the abolition of the slavery for pressure of the liberal abolitionists. However, the oligarchies formed for the colonels and farmers of the time had continued keeping the monopoly of the power in its areas, guaranteeing the politics of the parties that had been being born with the Republic and with it had the expansion of the right to the vote and the participation of the colonels in the destination of the country, thus the old feudals had insisted on remaining, becoming small cities, clienteles or? electoral corrals.
