While tension increased among the Cubans and Spanish Government, popular support of intervention began to spring up in the United States. Many Americans likened the Cuban revolt to the American Revolution, and they viewed the Spanish Government as a tyrannical oppressor. Historian Louis Pérez notes that "The proposition of war in behalf of Cuban independence took hold immediately and held on thereafter. Such was the sense of the public mood." Many poems and songs were written in the United States to express support of the "Cuba Libre" movement. At the same time, many African Americans, facing growing racial discrimination and increasing retardation of their civil rights, wanted to take part in the war. They saw it as a way to advance the cause of equality, service to country hopefully helping to gain political and public respect amongst the wider population.
