The Emperor's more notable political successes were achieved primarily because of the non-confrontational and cooperative manner with which he approached both issues and the partisan figures with whom he had to deal. He was remarkably tolerant, seldom taking offense at criticism, opposition or even incompetence. He did not have the constitutional authority to force acceptance of his initiatives without support, and his collaborative approach towards governing kept the nation progressing and enabled the political system to successfully function. The Emperor respected the prerogatives of the legislature, even when they resisted, delayed, or thwarted his goals and appointments. Most politicians appreciated and supported his role. Many had lived through the regency period, when the lack of an emperor who could stand above petty and special interests led to years of strife between political factions. Their experiences in public life had created a conviction that Pedro II was "indispensable to Brazil's continued peace and prosperity."
