Lyndon Baines Johnson became the thirty-sixth president of the United States on November 22, 1963, after John F. Kennedy was assassinated. He was sworn in on Air Force One in Dallas, stepping into a country filled with uncertainty and many unresolved issues. Johnson, known for his height, strong voice, and sharp political skills, acted quickly. His years in Congress had taught him how to persuade others and build alliances, and he now used those abilities as president. One of JohnsonÕs first major actions was to continue KennedyÕs work on civil rights. In 1964, he signed the Civil Rights Act, which banned discrimination in public places and at work. Passing it through a hesitant Senate required all his persuasive skills. The next year, he signed the Voting Rights Act, which removed obstacles that had kept Black Americans from voting for generations. These laws made lasting changes that are still felt today. Johnson kept going with his plans. He introduced the Great Society, a group of programs aimed at ending poverty and giving everyone a fair chance. Medicare and Medicaid provided health care for older people and low-income families. New education laws sent more funding to schools, especially in poorer areas. He also started the Department of Housing and Urban Development and launched Head Start for preschool children. Unemployment fell, and the economy stayed strong for much of his presidency. Many historians see these achievements as some of the most important since the New Deal. But the Vietnam War became a bigger problem each year. Johnson started with a small number of American troops there, but he gradually sent more. After reports of attacks in the Gulf of Tonkin in 1964, Congress gave him wide authority to increase military action. By 1968, over half a million American soldiers were fighting, and TV news showed scenes of battles and growing casualties at home. Protests against the war grew on college campuses and in cities. The Tet Offensive early that year made many Americans lose confidence, even though military leaders said it was a defeat for the enemy. Eventually, the pressure became too much for Johnson. On March 31, 1968, he surprised the nation by saying he would not run for president again. In his final months, he tried to begin peace talks in Paris, but progress was slow. When he left office in January 1969, Richard Nixon became president, and the war continued for several more years. Looking back, JohnsonÕs legacy is mixed. He passed laws that helped millions escape poverty, increased opportunities, and fought against legal racism. However, his choices in Vietnam led to many deaths, split the country, and hurt his reputation. He died in 1973 at his ranch in Texas, but the programs he started and the debates from his time still affect American life. In the end, he believed government could tackle big problems and showed it was possible, though he paid a high price for his errors.
