Samsung's Founder Skipped His Two Oldest Sons. Here's Why.

If you were the founder of the biggest company in South Korea and you had three sons, which one would you hand the keys to? Lee Byung-chull had an easy answer, by tradition: the eldest. That's not what happened, and the reason why is one of the wildest corporate succession stories to come out of Asia.

This isn't ancient history buried in a corporate museum. It's the origin story behind why Samsung today is run by the branch of the family it's run by — and why two of the founder's own children spent decades convinced they'd been cheated out of billions.

A Smuggling Scandal Took Down the "Rightful" Heir First

In 1966, a Samsung subsidiary called Korea Fertilizer Co. got caught trying to smuggle 55 tons of saccharin into the country disguised as construction materials. It became a national scandal. President Park Chung-hee personally ordered an investigation, and the fallout landed squarely on Lee Byung-chull's second son, Lee Chang-hee, who ended up in jail over it. The founder himself was forced to step down as chairman.

That single customs bust didn't just embarrass the family — it took the second son out of the succession picture entirely before he ever really had a shot.

The Eldest Son Got Six Months to Prove Himself

With the second son disgraced, Korean tradition pointed to the eldest: Lee Maeng-hee. He took the reins after the scandal, exactly as primogeniture would dictate. It lasted about six months.

By most accounts, Maeng-hee ran the place aggressively and clashed hard with his father's inner circle of longtime lieutenants — the executives Lee Byung-chull actually trusted to keep the empire running. Within half a year, the founder had resumed control himself, effectively firing his own son from the job he'd just handed him.

The Third Son Nobody Expected

So who was left? Lee Kun-hee, the third son, who by Korean custom shouldn't have been anywhere near the top of the list. When Lee Byung-chull was diagnosed with cancer in 1976, he made the culturally unusual call to formally skip both older sons and name Kun-hee as his successor — a decision that held until the founder's death in 1987, when Kun-hee officially took over as chairman.

It's the kind of move you'd expect to cause a permanent family rupture. It did.

Decades Later, the Bill Came Due — in Court

The resentment didn't stay quiet forever. In 2012, Lee Maeng-hee and his sister Lee Sook-hee sued their own brother, demanding shares they said their father had left them — worth roughly 4 trillion won, about $3.7 billion, in Samsung Electronics and Samsung Life Insurance stock that had reportedly been held under other people's names after their father's death.

Their argument was straightforward: their father had intended for them to inherit a cut of the empire too, and Kun-hee had quietly absorbed it all. Kun-hee's side argued the disputed shares weren't part of the original inheritance at all, and that even if they had been, the statute of limitations had long since expired.

  • The Seoul Central District Court ruled in Kun-hee's favor.
  • The Seoul High Court upheld that ruling on appeal.
  • Courts found the siblings had waited too long — Kun-hee had held the assets for well over a decade — to make a valid claim.

Lee Kun-hee kept every share. His older brother and sister walked away with nothing, decades after being passed over the first time.

Why This Story Keeps Echoing Through Korean Business

What makes this saga more than a one-off family drama is how familiar the shape of it is. A patriarch builds an empire, tradition says the eldest inherits it, and then a scandal, a personality clash, or a deathbed decision throws the whole plan out the window — leaving siblings to fight over the wreckage in court years later. It's practically a genre in Korean corporate history.

It's a strikingly similar pattern to what I covered in The Korean Gum Salesman Who Built an Empire—Then His Sons Tore It Apart, where a founder's succession choices set brothers against each other for years. And it's not just a Korean phenomenon either — the same dynamic of an unequal split triggering a lifelong legal war shows up in Mukesh Ambani Split From His Brother—Then Bailed Him Out of Jail, halfway across the world in India.

One persistent bit of chatter among Korea-watchers over the years is that the 2012 lawsuit was never really about the money at all — that Lee Maeng-hee, in his 80s by then, was making a symbolic last stand to have the original snub publicly acknowledged. That's speculation, not something either side has confirmed, but it's easy to see why the theory sticks: $3.7 billion is a strange hill to fight and lose on unless there's something more personal underneath it.

What This Means If You're Watching Any Family Business

The lesson isn't really about Samsung specifically — it's about what happens whenever "who's next" gets decided informally, based on a scandal, a six-month trial run, or a deathbed phone call, instead of a documented plan everyone agreed to in advance. The Lee family had roughly 46 years between the 1966 smuggling scandal and the 2012 lawsuit, and the fight never actually went away — it just went dormant.

If there's one thing to take from this today: whenever you read about a founder's succession plan, ask who got skipped and why — that's usually where the real story, and the eventual lawsuit, is hiding.
