Through the periods of settlement and the Portuguese rule we pass without notice of any woman of such prominence as to secure noteworthy mention, yet woman's influence must have been exerted and felt along each step of the path toward independence; they buttressed with their ambition and patriotism the enlarging spirit of nationality. So in the crisis that followed the declaration of independence in 1822, we need not be surprised to find a woman mentioned for heroism and patriotism. A Bahian girl, Maria de Jesus Medeiros, touched by her father's lament that he had no son to fight in his country's cause, and fired to action, disguised herself as a soldier and fought through the war. Her signal service, however, was on the occasion of the attempted landing of a powerful force of Lusitanians at the mouth of the Paraguassú River. Here Maria stood to resist the invader; at the head of a troop of Bahian Amazons she charged the oncoming soldiers, and, in spite of superior numbers, discipline and equipment, her valor and that of her companions prevailed and the discomfited Portuguese were driven back ingloriously.
In the absence of more specific information we may, moreover, gather that woman's influence was of notable moment in Brazil at the period of the independence, for we find that in 1821, Viscount de Pedra Branca, a deputy from Bahia to the Cortés at Lisbon, a prominent leader of the Liberals and a man of world-wide fajne, advocated that political liberty should be granted to Portuguese women, and the fact that the Cortés ignored his plea does not lessen the force of the presumption that woman in Brazil had acquired pronounced influence in politics at this time.
Among the women of the period of the empire the Crown Princess Isabel stands most prominent, and exception will hardly be taken to her inclusion in an account of Brazilian women. On her shoulders, as regent, devolved the government at intervals for many years. Remarkable for firmness of character, she was moreover imbued with lofty principles. The conspicuous act of her regency was the emancipation of the slaves, the decree for which she signed on July 10, 1888. In this act her courage and devotion were put to the severest test, yet realizing fully that her signing the decree would perhaps involve the overthrow of the empire and certainly lose her much popularity, or, at any rate, much influential support, she did not falter; nor did she content herself with a mere concurrence in the legislative course, but issued a declaration in which she exalted the act and glorified the emancipation. Her strength of character and her fidelity to her trust rose above all personal or party considerations. Soon followed, in fact, the quiet revolution of a few hours and the empire had vanished; a great republic was installed, and in this crisis Isabel again stood dignified and lofty, in her farewell manifesto to the Brazilian people proving her patriotism and voicing her womanly sentiment and unfeigned sorrow.
