Founded on February 6, 1869, at the St. Julien Hotel near Washington Square in New York City, Las Hijas de Cuba was created by de Villaverde as a political organization for women fighting for Cuban independence. During this time, membership in revolutionary and cultural clubs was restricted to males only, forcing women to form their own organizations. Fourteen Cuban and Puerto Rican women gathered at this initial meeting to discuss helping Cuban soldiers and to criticize the all-male independence organization,
Junta Revolucionaria de Cuba y Puerto Rico. As president of Las Hijas de Cuba, Emilia Casanova de Villaverde condemned this all-male club for their "annexationist maneuvers and betrayal of the independence movement." The members of Las Hijas de Cuba, aware of the United States' growing interest in controlling Caribbean nations, disapproved of the fact that the Junta considered the United States an ally. They feared that this would move Cuba closer to annexation by the United States rather than emancipation. The collective power of these women's efforts gained attention and garnered further support for Villaverde. The leaders of
Junta Revolucionaria de Cuba y Puerto Rico formed a new club called
La Liga shortly after, which came to be dominated by annexationists. Villaverde used her platform as president of Las Hijas de Cuba to become a more recognizable force within the independence movement. The organization played an important role in raising funds for Cuban soldiers during the
Ten Years' War. Additionally, as a representative of
Las Hijas de Cuba, Emilia Casanova de Villaverde presented the merits of Cuban liberation before the U.S. Congress on numerous occasions. She was the first Cuban woman granted the right to address the United States Congress on this issue. When her father was imprisoned in Havana during the
Ten Years' War, Villaverde spoke with U.S. government officials, including President
Ulysses S. Grant, asking for protection. Spain accused many members of the property-owning Creole class of "infidelity" during this contentious time, loosely defined as any actions disrupting the political order, and confiscated their property as punishment. President Grant agreed to protect her father from the Spanish government and soon after Villaverde's father was released. In 1871 and 1872, she again petitioned the United States Congress to support Cuban independence rather than Spanish colonial power. In 1871, Emilia Casanova de Villaverde pleaded the U.S. government for assistance after learning that eight medical school students at the
University of Havana were being held hostage by Spanish authorities. In 1872, she informed Washington officials of Spain's hostile behavior on the island of Cuba and presented an extensive argument detailing the economic advantages of aiding Cuba over Spain. Despite de Villaverde's efforts, the U.S. government decided it would be most strategic to side with a weak colonial power rather than a sovereign Cuba. In order to increase the international visibility of the Cuban emancipation struggle, she wrote to prominent European figures such as
Giuseppe Garibaldi and
Victor Hugo. In an 1869 letter to
Giuseppe Garibaldi, Villaverde stated her abolitionist views: "the beginning of our revolution means the freedom of our slaves, giving them arms and incorporating them in our patriotic ranks." Garibaldi responded to her appeal by stating that he supported Cuba's quest for freedom from colonial oppression, but he did not make any specific commitments to aid the movement. ==Later years==
