Though women played an integral role in the conquest of the New World, little has been written about their contributions. This Spanish-language work examines the lives and deeds of women who influenced the course of history in the Americas some 500 years ago. Covered in detail are the lives of María de Toledo, first woman governor in America; Isabel de Bobadilla, governor of Cuba and instrumental in the Spanish expedition to Florida; Ana Francisca de Borja, governor of Peru and a military leader; Beatriz de la Cueva, governor of Guatemala and a political leader; María de Peñalosa, governor of Nicaragua and a military strategist; Isabel Barreto y Quirós, first and only woman admiral of the Spanish navy; and mestizo leaders Francisca Pizarro and Leonor de Alvarado. Also covered are more than 40 other women of the same period—Spanish, Indian, and black—who held a wide variety of leadership positions. The book draws its information from the writings of respected early historians as well as historical documents from libraries and archives in Spain, Latin America and the United States.
