In 1961, the Soviet launch of the first human-crewed spacecraft caused President John F. Kennedy to propose to the country to be the first to send "a man to the Moon", a fact completed in 1969. Kennedy also faced a tense nuclear conflict with the Soviet forces in Cuba, while the economy grew and expanded steadily. A growing Civil Rights Movement, represented and led by African-Americans such as Rosa Parks, Martin Luther King, Jr. and James Bevel, used nonviolence to deal with segregation and discrimination. After Kennedy's murder in 1963, the Civil Rights Act of 1964 and the Voting Rights Act of 1965 were passed during the term of President Lyndon B. Johnson. Johnson and his successor, Richard Nixon, led a civil war in Southeast Asia, assistant to the unsuccessful Vietnam War. A generalized counterculture movement grew, driven by opposition to war, black nationalism and the sexual revolution. A new wave of feminist movements also emerged, led by Betty Friedan, Gloria Steinem and other women who sought political, social and economic equity.
