The biography of Dom Pedro I, first Emperor of Brazil, is a fascinating bit of little known history. The background is the story of the break with tradition when his father, John VI, driven from the Portuguese court, in the Napoleonic storm, took refuge in his American dominion, Brazil. Dom Pedro, adventurous, romantic, with the Braganza vitality, growing up in the new empire, became the hero of the day when he acceded to Brazil's demands for independence, was forced to abdicate in favor of his son, forced too to return to Portugal, where he fought for his daughter's inheritance. All the way along there was his mistress, Domitila de Castro Melo his devotion to his legitimate as well as his illegitimate children, and his place in the international picture. A robust picture of racy times, this should appeal to those interested in historical by-paths.
