After their experience of the perils and obstacles of government, the political figures who had arisen during the 1830s saw the Emperor as providing a fundamental source of authority essential for governing and for national survival. These elder statesmen began to die off or retire from government until, by the 1880s, they had almost entirely been replaced by a newer generation of politicians who had no experience of the early years of Pedro II's reign. They had only known a stable administration and prosperity and saw no reason to uphold and defend the imperial office as a unifying force beneficial to the nation. To them Pedro II was merely an old and increasingly sick man who had steadily eroded his position by taking an active role in politics for decades. Before he had been above criticism, but now his every action and inaction prompted meticulous scrutiny and open criticism. Many young politicians had become apathetic toward the monarchic regime and, when the time came, they would do nothing to defend it. Pedro II's achievements went unremembered and unconsidered by the ruling elites. By his very success, the Emperor had made his position seem unnecessary.
