When a Single Bullet Alters a Nation: Assassinations With Global Consequences

The majority of assassinations, with very few exceptions, are fueled by political motivation. Whether to seize power, seek retribution, undermine a regime, or prevent a new one from taking over, assassins have targeted those in power, often acting alone or on behalf of a larger organization or country. These events usually have unfortunate aftermaths, often involving political destabilization.

Although there is, on occasion, a positive outcome in the aftermath. A perfect example is the shooting death of Harvey Milk, the first openly gay officeholder in San Francisco. As tragic as his slaying was, it led to greater understanding and acceptance of the LGBTQ community nationwide. But what other assassinations have altered history's course, and what have we learned from these deaths?

To identify these moments in history, 24/7 Tempo has referred to such sites as Historyhit, Historyplex, History, and a few others. We exercised editorial discretion in compiling the final list, based on each assassination's long-term effects. Sometimes the outcome is almost immediately disastrous, but others caused a slow transformation in their affected organizations. Let's discuss these assassinations in detail now.

• Killed in: 44 B.C.
• Perpetrator(s): Roman senators

Julius Caesar won many victories for Rome when it was a republic but he angered the Senate by crossing the shallow river called the Rubicon, the border between Rome and its conquered lands, violating custom and setting off a civil war. Following his victory, he was made dictator "in perpetuity."

Fearing Caesar's aggrandizement of power, a conspiracy of senators, led by Marcus Brutus and Cassius Longinus, stabbed him to death. Unexpectedly, his death brought about the demise of the Roman Republic and Rome's beginning as an empire.

• Killed in: 1865
• Perpetrator(s): John Wilkes Booth

One of history's greatest what-ifs may just be what would have happened had Lincoln lived. His successor, Andrew Johnson, was the only Democrat and Southerner in Lincoln's administration during the Civil War. Lincoln was politically deft, could manage dissenting opinion, and sought to peacefully reintegrate the South into the Union.

Johnson seemed to be his opposite – stubborn, lacked allies, and could not keep the Radical Republicans from imposing a harsh peace on the former Confederacy. Some historians believe Lincoln would have run afoul with Radical Republicans also.

• Killed in: 1881
• Perpetrator(s): People's Will

Ordinary Russians had great hope for Tsar Alexander II. In his earlier years as the ruler of the far-flung Russian empire, Alexander had embraced liberal principles. In 1861, he freed the serfs and abolished corporal punishment as well as advocating for land reform. But more regressive voices got his ear and Alexander became more suspicious of those outside his circle, especially after several assassination attempts on him.

One attempt finally succeeded, when a radical group called the People's Will killed the tsar with a bomb thrown at his feet. Fearful of revolution, the tsars that followed Alexander were more repressive.

• Killed in: 1901
• Perpetrator(s): Leon Czolgosz

The United States became a global power under President McKinley after routing Spain in the Spanish-American War. Shortly after winning a second term, McKinley was shot and killed by anarchist Leon Czolgosz and was succeeded by Teddy Roosevelt, the youngest man to serve as president.

The energetic Roosevelt, a veteran of the Spanish-American War, embodied the vigorous American nation and sought to project its might around the world. Roosevelt was a different kind of Republican president, suspicious of corporate power and sympathetic to better working conditions for American laborers.

• Killed in: 1914
• Perpetrator(s): Gavrilo Princip

Heir to the throne of the polyglot Austro-Hungarian Empire, Ferdinand felt that the empire needed modernizing and the bureaucracy should be reformed, in contrast to his uncle, Emperor Franz Joseph. Ferdinand also believed much of the empire needed greater autonomy, including the recently annexed territory of Bosnia and Herzegovina, which contained a large Serb population.

On June 28, 1914, Serb nationalist Gavrilo Princip assassinated the archduke in Sarajevo, igniting the powderkeg that became World War I.

• Killed in: 1918
• Perpetrator(s): Bolsheviks

The assassination of the tsar and his family ended the 300-year reign of the Romanov dynasty. Tsar Nicholas II had been deposed in 1917 and his family was being held as hostages by the Bolsheviks. By killing all members of Russia's ruling family, the Bolsheviks removed the possibility of a restoration of the monarchy and paved the way for the creation of the Soviet Union, the world's first communist state. He was the fifth tsar to lose his life to an assassin.

• Killed in: 1948
• Perpetrator(s): Nathuram Vinayak Godse

Gandhi's strategy of nonviolent resistance led to the expulsion of the British from India in 1947. He was then assassinated by a Hindu fanatic a year after his nation gained independence. Gandhi's death robbed India of its founding father in its first years as a nation free from colonial rule but it was his effective methods served as an inspiration for civil rights leaders such as Dr. Martin Luther King Jr.

• Killed in: 1961
• Perpetrator(s): Opponents aided by the CIA

Lumumba, the president of the Republic of Congo (now the Democratic Republic of the Congo) was elected after the African nation became independent from Belgium. Lumumba was a Pan-African, anti-colonial leader who gravitated toward the Soviet Union.

The West could not abide the African nation moving toward the communist bloc and he was targeted for an assassination that likely involved the CIA. Overthrown in a coup, he was imprisoned and tortured, then shot by a firing squad. Lumumba's death poisoned relations between African nations and the West for years afterward.

• Killed in: 1963
• Perpetrator(s): CIA and Vietnamese assassins

The autocratic ruler of South Vietnam, President Ngô Đình Diệm, was nominally supported by the U.S. because he was an anti-communist, though his iron-fisted rule alienated elements of Vietnamese society and the military. The United States believed Diệm and his brother, Ngô Đình Nhu, were not doing enough to combat the communist insurgency.

After South Vietnam's military assured the U.S. of continued anti-communist efforts, America allowed a coup to proceed, which resulted in both brothers being stabbed and shot to death. Diệm's demise destabilized the South Vietnamese government and encouraged the North Vietnamese to denounce American intervention. A year and a half later, the first U.S. troops landed in South Vietnam, joining some 25,000 military advisors already in the country.

• Killed in: 1963
• Perpetrator(s): Lee Harvey Oswald

John F. Kennedy was the fourth American president to be killed while in office, slain by troubled U.S. Marine veteran Lee Harvey Oswald as Kennedy's motorcade passed through Dealy Plaza in Dallas. The national sorrow surrounding Kennedy's death, as well as the extraordinary parliamentary skills of his successor, Lyndon B. Johnson, led to the passage of two landmark anti-segregation laws – the Civil Rights Act and the Voting Rights Act.

Historians have speculated that if Kennedy had lived, the U.S. might not have committed thousands of troops to fight in Vietnam. We do know that Johnson accelerated the American troop buildup in Vietnam and that terrible consequences followed.

• Killed in: 1965
• Perpetrator(s): Members of the Nation of Islam

Malcolm X was a leader of the Nation of Islam until the year before his death when he renounced the group and formed the Organization of Afro-American Unity. He channeled the anger many African Americans felt in the early 1960s into a racial separatist movement that served as a counterpoint to the nonviolent approach to change advocated by Dr. Martin Luther King Jr.

Considered a turncoat by the Nation (sometimes referred to as Black Muslims), he received numerous death threats, and while addressing a meeting of the OAAU in a Manhattan ballroom, he was shot 21 times by Nation of Islam members (some say with the tacit approval of the NYPD or FBI).

Three men were convicted of the crime, but two were exonerated and released from prison in 2021. Malcolm X's mystique grew when his autobiography was published eight months ago, and he was a major influence on the Black Power movement.

• Killed in: 1968
• Perpetrator(s): James Earl Ray

The symbol of the civil rights movement, Dr. Martin Luther King Jr. had gone to Memphis to support a strike by the city's Black sanitation workers. It was here that he was slain. Racist career criminal James Earl Ray shot him as he stood on the balcony of his motel.

King's death triggered outrage and riots all over the U.S. His successors carried on his work to make America a more fair and just nation, but the movement's beacon of hope for racial unity was irreplaceable. Had King lived, he would have likely been a crusader for gun-control legislation to curb the gun violence ravaging the inner cities. King opposed the Vietnam War and probably might have voiced his opposition to the conflicts in Afghanistan and Iraq.

• Killed in: 1968
• Perpetrator(s): Sirhan Sirhan

After Lyndon B. Johnson decided not to run for re-election as the Democratic candidate for president in 1968, the race was wide open. Robert Kennedy, who had served his brother JFK and then Johnson as attorney general, jumped into the fray. He was seen as a potentially reconciling figure for a divided country because much of his campaign had focused on civil rights.

Kennedy tried to strike a nonviolent cord with a mostly minority crowd when he announced the death of Dr. Martin Luther King Jr. while on the campaign trail in April 1968.Two months later, on the night he'd won the California primary, Kennedy was slain by Jordanian refugee Sirhan Sirhan as he exited through the kitchen of the Ambassador Hotel in Los Angeles after a victory celebration.

Some political observers believed that even if he'd lived, he wouldn't have won the Democratic nomination, but he was young enough to have run again in 1972 and afterward.

• Killed in: 1978
• Perpetrator(s): Dan White

Milk was the first openly gay person to sit on the San Francisco Board of Supervisors. Following his election in 1977, he focused on issues like fair housing and ending workplace discrimination. Dan White, a former political ally who'd left his city supervisor's job because of mental health issues, asked Milk for help in regaining his job.

After Milk refused, White shot Milk and Mayor George Moscone at City Hall. White was convicted on the lesser charge of voluntary manslaughter, a verdict that touched off rioting in some parts of San Francisco. But it was Milk's death that brought national attention to issues in the LGBTQ community.

• Killed in: 1979
• Perpetrator(s): Irish Republican Army

Lord Mountbatten, a British military strategist during World War II and the last viceroy of British India was the great-grandson of Queen Victoria, the second cousin of Queen Elizabeth II, and a confidante of Prince Charles – whom he called his "honorary grandson." He was widely seen as a prominent symbol of both the royal family and the British Empire.

While he was fishing on a boat in Donegal Bay off Ireland's northwest coast, the Irish Republican Army detonated 50 pounds of gelignite hidden in his vessel, killing him and three others.It was a signal from the IRA that no one in the British elite was safe.

That attack, along with another the same day that killed 18 British soldiers, prompted the government of newly elected Prime Minister Margaret Thatcher to crack down on the IRA, beginning a long period of worse-than-usual relations between Ireland and Britain. It also caused the IRA to lose support from many former sympathizers.

• Killed in: 1979
• Perpetrator(s): Kim Jae Kyu

Under President Park Chung-hee, who took over the government of South Korea in a military coup in 1961, the country experienced spectacular economic growth through the 1970s. The former general's heavy-handed rule alienated many segments of South Korean society, leading demonstrations, sometimes violent, to erupt in Seoul, the nation's capital. South Korea yearned for a return to real democracy.

There are many theories as to his motive, but while Park was attending a banquet in Seoul, Kim Jae-kyu, chief of the Korean Central Intelligence Agency and a former friend of the president, shot him to death. Park's death paved the way for the eventual democratization of the country beginning in the late 1980s.

• Killed in: 1981
• Perpetrator(s): Khalid Ahmed Showky Al-Islambouli

Sadat was the president of Egypt who helped his country gain a measure of national redemption, following its humiliating defeat at the hands of Israel during the Six-Day War in 1967, by attacking the Jewish state in the Yom Kippur War of 1973. It was then that Sadat subsequently turned peacemaker and became the first Arab leader to forge a peace accord with Israel – thus winning himself and Israeli Prime Minister Menachem Begin the Nobel Peace Prize in 1978.

This achievement would cost Sadat his life. He was assassinated at a military parade by Islamic extremists in 1981, setting in motion the events that led to war in Lebanon in 1982 and, through the influence of Egyptian doctor Ayman al-Zawahiri, believed to have been involved in the assassination plot, eventually to the creation of al-Qaida.

• Killed in: 1984
• Perpetrator(s): Sikh extremists

Indira Gandhi led the world's largest democracy for 15 years. She was the daughter of Jawaharlal Nehru and independent India's first prime minister (no relation to Mahatma Gandhi). When Sikh separatists took over the Golden Temple in Punjab, the holiest Sikh shrine, she sent in the military to expel them from the site.

Sikhs were outraged by the violence of her reaction, and two of her Sikh bodyguards shot her while she walked in the garden of her official residence. Her death ignited violence all over India and thousands of Sikhs were killed. Police and government officials did almost nothing to stop the fighting.

Violence against India's ruling class would continue. Her death also allowed her son, Rajiv Gandhi, to assume her office and his policies of liberalization and globalization had lasting effects on the Indian economy.

• Killed in: 1991
• Perpetrator(s): Suicide bomber

Rajiv Gandhi, son of Indira Gandhi, succeeded his mother as prime minister following her assassination, serving until 1989. While he was in office, he sent the Indian Peacekeeping Force to Sri Lanka to help the government combat Tamil rebels. After he stepped down, he was campaigning for another politician in the Tamil-majority Indian state of Tamil Nadu when a female suicide bomber, a member of the Liberation Tigers of Tamil Eelam, triggered an explosive concealed beneath her dress, killing him and 14 others.

Gandhi's death created a political vacuum in India and led to the rise of numerous regional political parties as people came to distrust national politics. Laws passed after the assassination also gave the government greatly increased anti-terrorism powers.

• Killed in: 1994
• Perpetrator(s): Possibly opposition party

The death of Rwandan president Juvénal Habyarimana, possibly at the hands of the opposition party, led to one of the worst tragedies of the 20th century. Habyarimana was the second president of the Republic of Rwanda, formerly a German and then a Belgian colony, serving from 1973 to 1994. The nation had long been torn by strife between its two major ethnic groups, the Hutu and the Tutsi.

A plane, carrying Habyarimana and the president of Burundi, was shot down by surface-to-air missiles over the presidential palace. Both presidents were Hutu, and suspicion immediately fell on members of the Tutsi Rwandan Patriotic Front, with whom Habyarimana had been negotiating. Some, though, suspected Hutus were opposed to any agreement with the RPF.

Whoever was responsible for the assassination was most likely responsible for igniting the horrific Rwandan Genocide, which claimed the lives of between 800,000 and a million Tutsi and moderate Hutu.

• Killed in: 1995
• Perpetrator(s): Yigal Amir

Prime Minister Yitzhak Rabin of Israel was involved in ongoing peace talks with Palestinian representatives, which led to the Oslo Accords, aimed at resolving Israeli-Palestinian issues and spurring Israeli withdrawal from areas of the West Bank and the Gaza Strip. Rabin and Palestine Liberation Organization leader Yasir Arafat were awarded the 1994 Nobel Peace Prize for their efforts.

An ultranationalist Israeli named Yigal Amir thought that Rabin was betraying Israel and his fellow Jews, and after a peace rally in Tel Aviv, approached Rabin's car and shot him. His death was a major setback to the Middle East peace process and ushered in a period of political instability in Israel.

• Killed in: 2006
• Perpetrator(s): Andrei Lugovoi

Former Russian spy Alexander Litvinenko, who had defected to Great Britain, was killed by the radioactive poison polonium, that was put in his tea. An official British investigation into the incident determined that former KGB bodyguard Andrei Lugovoi and his accomplice, Dmitry Kovtun, were responsible.

They almost certainly killed Litvinenko with approval from Russian leader Vladimir Putin. The episode emboldened Putin to push his agenda forward, regardless of the outcry from abroad, with results being felt in Ukraine to this day.

• Killed in: 2007
• Perpetrator(s): Suicide bomber

Benazir Bhutto, daughter of a former Pakistani prime minister, was the first female prime minister of Pakistan and the first woman to lead a democratic government in a Muslim-majority country. She served two terms in office, from 1988 to 1990 and again from 1993 to 1996. After leaving office the second time, she remained in the country as opposition leader, then left for self-imposed exile in Dubai for eight years – remaining active in Pakistani politics from afar.

She returned to Pakistan in 2007 with thoughts of running again for prime minister. On Dec. 27, however, when she opened the hatch on a bulletproof vehicle to wave to a crowd in Rawalpindi, an assassin shot her. The hitman then detonated a suicide vest, killing Bhutto and 22 others. Who ordered the hit is unknown.

Even though the manner of her death was shocking, political observers were not surprised she was killed. Bhutto was a controversial figure and her earlier governments were tainted by corruption – and Islamic fundamentalists also opposed her stature as a prominent female politician. Her death touched off rioting in cities, with trains set on fire, and a period of political instability. Because she was pro-Western, her death led to a deterioration of Pakistan's relations with the U.S. and other countries.

• Killed in: 2011
• Perpetrator(s): US special forces

Osama bin Laden, the Al-Qaida leader who was the mastermind of the Sept. 11 terrorist attacks in the United States and the symbol of the war on terrorism, was found by U.S. special forces in a hiding place in Pakistan and was shot to death. His killing not only weakened a top terror organization but also provided a trove of information that helped the U.S. prevent future attacks and boosted American morale.

However, it also led to the rise of ISIS to fill the power vacuum left by a weakened al-Qaida. Former President Bill Clinton stated that he had an opportunity to kill bin Laden before the Sept. 11 attacks but chose not to do so because it would have meant destroying the town of Kandahar and killing 300 people, making him no better than bin Laden. You can only wonder what history would have been like with the earlier eradication of bin Laden.
