Whether it's the burning monk, the JFK assassination, or Woodstock, these images are still seared into the American consciousness 50 years later.
This now iconic image of Marxist revolutionary Ernesto "Che" Guevara depicts him at the March 5, 1960 funeral for the victims of the La Coubre explosion. Guevara believed that the destruction of the French freighter in Havana harbor and the 75-100 resulting deaths were a deliberate act of sabotage on the part of the U.S. because of Cuba's new communist government following the revolution the year before.
Guevara helped carry out that revolution before attempting to foment similar uprisings elsewhere around the world, which helped make him an enemy of the U.S. Eventually, in 1967, C.I.A.-assisted Bolivian forces captured Guevara in Bolivia and executed him.Alberto Korda/Wikimedia Commons

At 12:30 p.m. CST, on Nov. 22, 1963, the world was still moving. President Kennedy's uncovered 1961 Lincoln Continental four-door convertible limousine had just entered Dealey Plaza in Dallas, Texas.
Nellie Connally, the First Lady of Texas who was riding in the front seat of the president's car, turned herself around and said, "Mr. President, you can't say Dallas doesn't love you."
President Kennedy's reply were his last words: "No, you certainly can't."

On Oct. 30, 1961, the Soviet military successfully tested Tsar Bomba, the most powerful weapon ever detonated. Its blast was five miles in diameter with a yield of 50 megatons -- 25 times more powerful than all the munitions used in World War II (including the two atomic bombs dropped by the U.S.) put together.Wikimedia Commons
Rumors of an affair between President John F. Kennedy and Marilyn Monroe persist to this day. Perhaps fueling the rumors more than any other incident was Monroe's sultry rendition of "Happy Birthday" sung to Kennedy at Madison Square Garden on May 19, 1962.

For 13 days in the fall of 1962, it seemed as if the world was going to end. Known as the Cuban Missile Crisis, this tense period saw Soviet forces attempt to move nuclear missiles to Cuba, just 90 miles from the coast of Florida. The U.S. responded by blockading Cuba with its own military forces. It was the closest the Cold War ever came to all-out nuclear annihilation.
Ultimately cooler heads prevailed and both sides agreed to back their nuclear weapons farther away from the enemy's borders.

The following summer, President John F. Kennedy traveled to Berlin, Germany, the city that stood at the border of the communist and non-communist worlds, literally divided down the center by a wall.
In Berlin, Kennedy hoped to underline U.S. support for all people on the non-communist side of the world's great political divide, famously declaring "Ich bin ein Berliner" ("I am a citizen of Berlin"), which many incorrectly mistranslated as Kennedy proclaiming himself to be a jelly doughnut.AFP/Getty Images
At home, millions of Americans hoped to overcome racial divides. By 1963, despite fierce opposition, the civil rights movement had begun gaining momentum. In August, activists including Martin Luther King Jr. led the March on Washington for Jobs and Freedom, which drew approximately 250,000 people to the nation's capital in an unprecedented show of support for the movement.Wikimedia Commons

Joining activists and political leaders like King at the March on Washington were folk singers like Joan Baez and Bob Dylan.
Artists like these had come to represent the voice of both the younger generation and highlight the plight of nation's oppressed through verse -- a trend that would only grow as the decade went on.Wikimedia Commons

Jack Ruby fatally shoots alleged Kennedy assassin Lee Harvey Oswald as Dallas police escort the latter to a transport vehicle the day after Kennedy's death.
Ruby told several witnesses immediately after shooting Oswald that he was trying to help the city of Dallas "redeem" itself in the public's eye, and spare "...Mrs. Kennedy the discomfiture of coming back to trial."Wikimedia Commons
On March 26, 1964, the decade's two most prominent civil rights leaders shared their only meeting.
As Martin Luther King Jr. (left) was leaving a news conference, Malcolm X (right) stepped out of the crowd, extended his hand, and smiled.
"Well, Malcolm, good to see you," King said.
"Good to see you," X replied.

As was the case with music and politics, fashion also took a bold leap forward in the 1960s.
The famous 1965 Mondrian Collection by French designer Yves Saint Laurent took an innovative approach to fashion by combining classical Western forms with the aesthetics of modernist fine art.

On Aug. 11, 1965, the Los Angeles Police Department pulled over an African-American man named Marquette Frye for drunk driving. His arrest soon evolved into a roadside scuffle and many quickly accused the officers of police brutality. Six days of riots followed in the city's predominantly African-American Watts neighborhood.
To contain the riots, the LAPD needed nearly 4,000 members of the California Army National Guard. In total, the riots resulted in 34 deaths and $40 million in property damage.Wikimedia Commons
More than any other two people, Martin Luther King Jr. and President Lyndon Johnson (meeting here in the White House on March 18, 1966) may have had the greatest impact on civil rights in the 1960s -- the former as the movement's de facto leader and the latter as the one who pushed the landmark Civil Rights Act of 1964 into law.
While they differed in approach, the two held each other in high esteem. As King later wrote of Johnson: "His approach to the problem of civil rights was not identical with mine — nor had I expected it to be. Yet his careful practicality was, nonetheless, clearly no mask to conceal indifference. His emotional and intellectual involvement was genuine and devoid of adornment. It was conspicuous that he was searching for a solution to a problem he knew to be a major shortcoming in American life."Wikimedia Commons

Soon, President Johnson called in the 82nd and 101st Airborne Divisions to aid the overwhelmed police and quell the rioting. More than 8,000 National Guardsmen joined in as well. Many accused these men of using unnecessary force during the operation.Stringer/Getty Images
When it was all said and done, the riots resulted in 43 deaths, hundreds of injuries, more than 7,000 arrests, and about $50 million worth of damage.Stringer/Getty Images
The following year, on April 4, 1968, the civil rights movement took another devastating hit with the assassination of Martin Luther King Jr. at the hands of James Earl Ray (pictured).
After a failed career as a pornographer in Mexico, Ray had returned to the U.S. -- where he was wanted for escaping prison -- to take dance and bartending lessons before setting in motion his plan to kill King.
Ultimately, Ray's crimes earned him 99 years in prison, where he died in 1998 at age 70.Wikimedia Commons

King's assassination once again brought racial tensions to a head in more than 100 cities across the country.
Washington, D.C. (pictured) saw the worst of it. Over the five days following King's death, rioters burned more than 1,000 buildings, causing about $27 million in damage and prompting President Johnson to call in 13,600 federal troops.Wikimedia Commons
In early 1968, the violence intensified overseas as well, as fighting in Vietnam reached new heights with the communists' devastating Tet Offensive and the Americans' brutal My Lai Massacre.

Elsewhere in Europe in 1968, liberal leadership in Czechoslovakia attempted to loosen overarching Soviet restrictions on human rights including free speech and travel. Clashes between protesters and Soviet forces reached a fever pitch when the latter invaded on August 20 and countless demonstrators took to the streets to fight back.
In the end, Soviet forces withdrew and granted Czechoslovakia some freedoms, but the country nevertheless remained under Soviet control, with future leaders tightening back up the restrictions that had been briefly loosened in 1968.AFP/AFP/Getty Images

On June 5, 1968, Sirhan Sirhan assassinated Senator Robert Kennedy in Los Angeles. The killer, a Palestinian/Jordanian immigrant, is believed to have carried out his plot in response to Kennedy's support of Israel in the country's Six-Day War with Egypt, Jordan, and Syria the year before.
After the assassination of John F. Kennedy five years earlier, many took the killing of his brother as a sign that, by 1968, the U.S. had truly reached its breaking point.Wikimedia Commons
