On March 12, 1930, Indian nationalist leader Mahatma Gandhi led a nonviolent protest against the British Empire. The march protested the British tax on salt, a necessity of everyday life. Gandhi called for Indians to illegally make salt or buy it illegally. More nonviolent protests against the tax were mounted in large cities across India, and Gandhi's methods eventually led to India's independence.
Rosa Parks became an inspiration for the modern civil rights movement when she was arrested in Montgomery, Alabama, on December 1, 1955, after refusing to give up her seat to a white passenger on a city bus. For 381 days, African-Americans boycotted public transportation to protest Parks' arrest and, in turn, segregation laws. The boycott led to a 1956 Supreme Court ruling desegregating public transportation in Montgomery. Soon after, Parks was photographed near the front of a bus in what became an enduring image of the civil rights movement.
