The art of the grudge

When ambition turns toxic: The 10 most explosive rivalries of all time

History isn’t just a dry timeline of treaties and discoveries; it is a messy, vibrant, and often blood-soaked record of human ego. From the royal courts of England to the film sets of Hollywood, some of the world's most significant progress—and destruction—has been fueled by individuals who simply could not stand one another. Would you like to know more about 10 feuds born of political ambition, sibling rivalry, and corporate greed? Tune in now!

Way before Game of Thrones became a hit TV show, there was a real-life bloodbath known as the Wars of the Roses. This 15th-century dynastic struggle pitted two branches of the royal House of Plantagenet against each other: the Lancasters (symbolized by a red rose) and the Yorks (a white rose).

For thirty years, the English throne was a revolving door of kings, marked by brutal battles and Shakespearean betrayals. The feud finally ended when Henry Tudor (a Lancaster) defeated Richard III (a York) at Bosworth Field, marrying Elizabeth of York to unite the houses and birth the Tudor dynasty.

In the early days of the American Republic, politics wasn’t just a war of words, it was a matter of honor. Alexander Hamilton and Aaron Burr were both brilliant, ambitious men, but Hamilton spent years systematically undermining Burr’s career, calling him "dangerous" and "unprincipled."

The tension boiled over after the 1804 New York gubernatorial election. Burr, tired of Hamilton’s constant sabotage, challenged him to a duel. On the heights of Weehawken, New Jersey, Burr fired the shot that ended the life of the First Secretary of the Treasury. While Burr survived, his political reputation never did.

This wasn't just a personal spat, it was ultimately called the War of Currents. Thomas Edison, the "Wizard of Menlo Park," had bet his fortune on Direct Current, while his former employee, the eccentric genius Nikola Tesla, championed Alternating Current.

Edison went to extreme lengths to discredit Tesla and his financier, George Westinghouse, even orchestrating public electrocutions of animals to "prove" Alternating Current was dangerous. However, physics was on Tesla's side. Alternating Current could be transmitted over long distances far more efficiently than Direct Current. Today, when you flip a light switch, you’re seeing the legacy of Tesla’s victory in one of history’s greatest scientific rivalries.

The definitive American family feud took place in the Appalachian backcountry along the West Virginia-Kentucky border. What started as a lingering bitterness from the Civil War and a dispute over a stolen pig spiraled into a decade of surprise attacks, arson, and murder.

By the time the violence peaked in the 1888 "New Year’s Massacre," dozens had been killed or imprisoned. It took over a century for the families to officially sign a truce, proving that some grudges are written into the very DNA of a community.

In the late 1890s, the battle for the attention of New Yorkers gave birth to Yellow Journalism. Joseph Pulitzer (New York World) and William Randolph Hearst (New York Journal) competed to see who could print the most sensational, lurid, and often fabricated headlines.

Yet, this seemingly frivolous feud actually had geopolitical consequences. Both men used their papers to drum up pro-war sentiment during the Spanish-American War to boost circulation. Their race to the bottom changed the media landscape forever, teaching us that when news becomes a weapon in a personal rivalry, truth is usually the first casualty.

Hollywood’s most legendary "mean girl" feud was a masterclass in professional sabotage. These two powerhouse actresses spent decades trading insults and competing for roles. Their rivalry was so famous that it was leveraged for the 1962 film What Ever Happened to Baby Jane?

On set, Crawford reportedly put weights in her pockets during a scene where Davis had to drag her, just to hurt Davis's back. When Davis was nominated for an Oscar for the film, and Crawford wasn't, Crawford contacted the other nominees and offered to accept the award on their behalf if they won, which she did, just to spite Davis.

Prohibition-era Chicago was a chessboard, and Capone and Moran were the two most violent players. Capone’s Italian "Chicago Outfit" and Moran’s "North Side Gang" fought a bloody turf war for control of the city’s illegal booze trade.

The feud reached its horrific climax on February 14, 1929, with the St. Valentine’s Day Massacre, where Capone’s men, dressed as police, gunned down seven of Moran’s associates. Moran famously remarked, "Only Capone kills like that." Though Moran escaped the massacre, the event effectively broke his power and marked the beginning of the end for the gangland wars of the 1920s.

You might recognize these as sportswear giants, but they began as a bitter rift between two brothers, Adolf ("Adi") and Rudolf ("Rudi") Dassler. After a mysterious fallout during WWII—legend says it involved a misunderstood comment in a bomb shelter—the brothers split their shoe company in 1948.

Adi formed Adidas, and Rudi formed Puma. The feud divided their hometown of Herzogenaurach so deeply that it became known as "the town of bent necks," because residents would look at a person’s shoes before deciding whether to speak to them. The brothers were buried at opposite ends of the local cemetery, never having reconciled.

The two titans of "The Lost Generation" started as friends, but their relationship devolved into a toxic mix of jealousy and judgment. Hemingway, who prized masculine"stoicism, mocked Fitzgerald for his perceived weakness and his turbulent marriage to Zelda.

In his memoir A Moveable Feast, Hemingway took several posthumous jabs at Fitzgerald’s character and talent. Fitzgerald, meanwhile, was both awed and intimidated by Hemingway’s success. It was a rivalry of the pen where mutual admiration was eventually smothered by the crushing weight of their respective egos.

The only thing more intense than a professional feud is a sibling one. These two Oscar-winning sisters didn't speak for the last 38 years of Fontaine’s life. The friction began in childhood but went nuclear when they were both nominated for Best Actress in 1942.

Fontaine won, and when de Havilland later won her own Oscar, she famously snubbed Fontaine’s attempt to congratulate her backstage. They disagreed on everything from their mother's medical care to who deserved the most fame. It remains the most enduring and frosty sibling rivalry in the history of the arts.

What is a Twix, anyway?

Do you know what or who your favorite candy is named after?

If you have never seen a Reese’s Peanut Butter Cup or an Almond Joy but only read the name, chances are that you would be able to form an idea of the product. But this is not always the case with candies and candy bars. Many of these delicious treats have names that do not seem to have any logical connection with their contents. But they do have it. Take a look at the following 12 famous examples. Did you know about any of these?

The Snickers bar, introduced by the Mars, Inc. company in 1930, was named after the Mars family's favorite horse. Snickers lived on their farm and was dearly loved.

Sadly, the horse passed away shortly before the candy bar's release, so naming the bar after him served as a tribute to their cherished companion.

The name Kit Kat traces back to the 18th-century Kit-Cat Club in London, which itself was named after Christopher Catling, a pastry chef nicknamed "Kit Cat."

Rowntree's, the company that launched the bar in the 1930s, chose the name to give it a touch of history and sophistication.

M&M’s stands for Mars and Murrie, the last names of the candy’s creators. Forrest Mars of the Mars Company teamed up with Bruce Murrie, son of Hershey’s president, and the delicious, colorful candies were born.

Starburst got its name to reflect the candy’s bold, fruity flavors, like a burst of flavor in every bite.

Originally launched in the UK in 1960 as Opal Fruits, it was renamed Starburst for the U.S. release in 1967, likely to create a more dynamic, space-age image during the height of the space race.

Sour Patch Kids were originally called Mars Men when they debuted in the 1970s, playing off the era’s fascination with space.

When introduced in the U.S. in 1985, the name changed to Sour Patch Kids to tap into the Cabbage Patch Kids craze. The new name also highlights the candy’s signature sour-then-sweet taste.

The 3 Musketeers bar got its name in 1932 from its original trio of flavors: chocolate, strawberry, and vanilla. Each bar came in three separate pieces, echoing the "three" theme.

The name also nodded to the popular novel The Three Musketeers. During World War II, rising costs of sugar and fruit led to the discontinuation of strawberry and vanilla, leaving only chocolate—the version we still enjoy today.

The Milky Way bar was named after a popular malted milk drink from the 1920s, not the galaxy.

The name was meant to suggest a creamy, rich flavor, echoing the appeal of the drink that inspired it.

Skittles were named after the old European game of skittles, similar to bowling. The candy's round shape was the connection with the original game.

First produced in the UK in 1974 by a British distributor for Mars, Inc., the name was likely chosen to convey fun and flavor variety.

The PayDay bar got its name because it was first made on—yes, you guessed it—a payday at the Hollywood Candy Company. The timing inspired the name, which stuck.

Introduced in 1932 during the Great Depression, it was marketed as an affordable, energy-packed snack. With its combination of peanuts and caramel, it offered real substance, which can be a metaphor for a little "payday" in candy form.

Anyone would be forgiven for thinking that the Baby Ruth bar was named after baseball legend Babe Ruth—but that’s not the case. The candy does indeed sound like it could honor the sports icon, but the Curtiss Candy Company claimed otherwise.

They stated that it was named after Ruth Cleveland, the daughter of President Grover Cleveland.

The 100 Grand bar was originally called the $100,000 Bar, inspired by quiz shows with big prizes, such as The $64,000 Question.

In the mid-1980s, Nestlé renamed it 100 Grand, likely to ease trademark issues and generate a greater appeal by simplifying the name.

The name Twix is a blend of the words "twin" and "sticks," referring to its two chocolate-covered biscuit bars. It was first released in the UK in 1967 under the name Raider.

When introduced in the U.S. in 1979, the bar was renamed Twix. The twin-bar design later inspired the playful "Left vs. Right Twix" advertising campaign.
