completely forgotten during the span of nearly 300 years since his expedition. This began to change beginning in the 1840s when Emperor Dom Pedro II, successor and son of Pedro I, sponsored research and publications dealing with Cabral's life and expedition through the Brazilian Historic and Geographic Institute. This was part of the Emperor's ambitious larger plan to foster and strengthen a sense of nationalism among Brazil's diverse citizenry—giving them a common identity and history as residents of a unique Portuguese-speaking empire, surrounded by Hispanic-American Republics. The initial resurgence of interest in Cabral had resulted from the rediscovery, in 1839, of his resting place by the Brazilian historian Francisco Adolfo de Varnhagen (later Viscount of Porto Seguro). The completely neglected state in which Cabral's tomb was found nearly led to a diplomatic crisis between Brazil and Portugal—the latter then ruled by Pedro II's eldest sister, Maria II. In 1871, the Brazilian Emperor—then on a trip to Europe—visited Cabral's gravesite and proposed an exhumation for scientific study, which was carried out in 1882. In a second exhumation during 1896, an urn containing earth and bone fragments was allowed to be removed. Although his remains still lay in Portugal, the urn was eventually brought to the old Cathedral of Rio de Janeiro in Brazil on 30 December 1903. Cabral has since become a national hero in Brazil. In Portugal, however, he has been much overshadowed by his rival Vasco da Gama. Historian William Greenlee argued that Cabral's exploration is important "not only because of its position in the history of geography but because of its influence on the history and economics of the period." Though he acknowledges that few voyages have "been of greater importance to posterity", he also says that "few have been less appreciated in their time." Nevertheless, historian James McClymont affirmed that "Cabral's position in the history of Portuguese conquest and discovery is inexpungable despite the supremacy of greater or more fortunate men." He concluded that Cabral "will always be remembered in history as the chief, if not the first discoverer of Brazil." Intentional discovery hypothesis A controversy that has occupied scholars for more than a century concerns whether Cabral's discovery was by chance or intentional. If the latter, that would mean that the Portuguese had at least some hint that a land existed to the west. The matter was first raised by Emperor Pedro II in 1854 during
