The year's political, social, and economic climate made it such that things very easily could — and very often did — turn violent.

Indeed, as protests and riots ruled the day, many of America's greatest cities instead resembled war zones.

Fittingly, one of the biggest factors in making the U.S. of 1968 look like a war zone was the actual war zone in which the country's troops fought in Vietnam. The country's deeply divided stance on the war helped further drive a wedge into a country already in danger of tearing itself apart.

In fact, one of the most devastating incidents that helped reveal the war's brutality occurred not long after 1968 began.

It wasn't just U.S. involvement in Vietnam that brought tensions to the breaking point. Chief among the country's domestic concerns was race relations, as the African-American population was growing ever more angry at the myriad injustices they faced day in and day out.

The following day, April 4, King was assassinated by James Early Ray at the Lorraine Motel in Memphis.

After King's death, in at least 100 cities across the nation, the rioting began almost immediately.

Out of all the cities brought to the brink of disaster, none took as hard a hit as the nation's capital. The rioting in Washington, D.C. began the very same day that King was killed and lasted for four days.

By the end of the D.C. riots, 12 lay dead with another 1,000 injured. In addition, throughout the two weeks surrounding the riots, local authorities responded to more than 1,000 separate fires.

Largely due to the fires, as well as widespread looting, more than 1,000 buildings incurred damage with an estimated total cost of about $13 million. Some areas of the city lay at least partially vacant and dilapidated well into the 1990s.Warren K. Leffler/Library of Congress

On April 11, one week after King's death, President Lyndon B. Johnson signed into law the landmark Civil Rights Act of 1968, which largely provided for fair housing regardless of race and granted a number of basic rights to Native Americans.

While matters of civil rights wreaked havoc on the homeland in the first half of 1968, U.S. involvement in Vietnam grew more contentious and more deadly.
In various waves throughout the year, the North Vietnamese and Viet Cong forces launched decisive strikes, collectively known as the Tet Offensive, against the U.S. and South Vietnamese forces.

The Tet Offensive, the largest campaign launched by either side to that point, devastated U.S. and South Vietnamese forces, allowing the North to strike more than 100 towns and cities, including 36 of 44 provincial capitals.
Moreover, while the Northern forces were eventually beaten back, the Tet Offensive marked a turning point in U.S. public opinion against the war, as many now saw that the North was a formidable opponent, and not one that would be beaten with ease, as the U.S. had largely beed led to believe.

Further helping to turn American public opinion against the war was the Mỹ Lai Massacre.
On March 16, approximately 100 American soldiers stormed the Sơn Mỹ village (which included the Mỹ Lai hamlet) and slaughtered somewhere between approximately 350 and 500 civilians, including men, women, children, and infants. An untold number of further victims were raped, injured, and mutilated as soldiers razed the village, burning much of it to the ground.Ronald Haeberle/Wikimedia Commons

Some of the men involved claimed that they had been told that everyone in the village was either an enemy Viet Cong operative or at least a Viet Cong sympathizer. Others claimed that they massacred everyone out of fear that even women and children would often booby-trap themselves with mines and grenades.
Nevertheless, it was perhaps the ugliest massacre in U.S. military history, and despite the military's cover-up attempts, reports finally surfaced the following year and helped change many American minds about the war in Vietnam.Ronald Haeberle/Wikimedia Commons

While events like the Mỹ Lai Massacre turned many Americans against the war — especially eligible-to-serve young men, many of whom burned their draft cards in protest — the country remained bitterly divided on the matter throughout 1968.

Between April 23 and 30, New York's Columbia University, one of many campuses to endure rioting in 1968, descended into civil war over issues related to both the Vietnam War and civil rights.
For eight days, two different protest groups — one rebelling against Columbia's plans for a segregated gym and its encroachment into Harlem, the other against Columbia's recently revealed connections to a Department of Defense-affiliated weapons think tank — battled with both student counter-protestors and the police, who eventually moved in with tear gas to put an end to this round of demonstrations.Bettmann/Contributor via Getty Images

As protests of all stripes and the killing of Martin Luther King Jr. brought America to its knees, the country lost another of its most inspiring leaders on June 5 with the assassination of Senator Robert F. Kennedy.
In the midst of a presidential campaign that promised greater racial equality and deescalation in Vietnam, Kennedy was shot by Sirhan Sirhan — a Jordanian man who disagreed with Kennedy's backing of Israeli actions in Palestine — at the Ambassador Hotel in Los Angeles.

In the months surrounding Kennedy's death, thousands of demonstrators descended upon Washington, D.C. as part of the Poor People's Campaign, a mass protest organized by Martin Luther King Jr. before his death, in response to the government's neglectful and harsh treatment of the impoverished across the country.
For six weeks in May and June, demonstrators rallied marched, and even set up a 3,000-person tent settlement for poor people on the Washington Mall, naming it Resurrection City.ARNOLD SACHS/AFP/Getty Images

Following the Poor People's Campaign, the political establishment faced even more intense protest from the disenfranchised later that summer during both of the major parties' conventions ahead of the presidential election.
First came the Republican National Convention, held in Miami between August 5 and 8, which drew protests related issues of both race and the Vietnam War.Bettmann/Contributor via Getty Images

Three weeks later came the Democratic National Convention in Chicago, which saw even more intense protests that descended into full-blown riots.
Between August 22 and 30, more than ten thousand protestors — largely those opposed to the Vietnam War and many from the anti-establishment Youth International Party — flocked to the city and often clashed with the police and National Guard.Bettmann/Contributor via Getty Images

After the violence on the night of the 28th subsided, the protests and accompanying police presence continued throughout the convention's duration.

Inside the convention, things weren't as physically violent, but were every bit as contentious. The party lay bitterly divided over many issues, especially the Vietnam War and the subsequent treatment of antiwar protestors.

On September 5 in Oakland, civil rights activist and Black Panther Party co-founder Huey Newton waits in his jail cell while a jury decides his fate on charges of murdering one Oakland police officer and wounding another the preceding fall.
Newton was convicted, however subsequent retrials ended in hung juries and the authorities eventually dismissed the case. While Newton's guilt or innocence in the shootings remains a matter of contentious debate, his Black Panther movement would go on to have a large impact on civil rights in the U.S. in the ensuing years.Bettmann/Contributor via Getty Images

On September 7, demonstrators from the National Women's Liberation Movement picket the Miss America Pageant in Atlantic City, New Jersey.
More than 400 protestors railed against the pageant on charges of promoting consumerism (in reference to the pageant's sponsors), racism (the only finalists ever selected had been white), and misogyny. While none of these protestors actually burned their bras, an erroneous report in the New York Post claimed that they did and hence the often dismissive stereotype of the bra-burning feminist was born.Bettmann/Contributor via Getty Images

In a year already subject to violence and strife along political and social lines, 1968 could not avoid horrific accidents, either.
On November 20, the Consol No. 9 mine in Farmington, West Virginia exploded in one of the worst disasters of its kind in U.S. history. Ultimately, 78 miners perished and, in response, Congress soon passed new legislation strengthening health and safety standards for such workers.Wikimedia Commons

Environmental disaster of another kind and severity altogether had struck New York City earlier in the year when the city's sanitation workers went on strike during a contract dispute. In a scene emblematic of the kind of year that the U.S. was having, trash piled up in the streets of the country's largest city as protests raged among frustrated sanitation workers and angry civilians alike.

As 1968 drew to a close, violent protest fittingly ruled the day once more, chiefly at a protracted and intense conflict at San Francisco State College starting in November. Several student groups rose up in order to call for wider ethnic representation in both courses offered and faculty hired. When police were called in, the clashes sometimes grew violent, including one on December 3 (pictured).Bettmann/Contributor via Getty Images
