Stories of great fortunes are fun to read: palaces, jewels, caravans of gold. They also carry surprisingly practical lessons for ordinary families, because the same forces that made or broke kings — inflation, liquidity, habits and time — act on a monthly SIP too. Here are six of history’s richest people and the one lesson each of them teaches.
Croesus: the king who gave us coins
“As rich as Croesus” is still a saying, 2,500 years after he ruled Lydia, in what is now Turkey. Lydia is credited with some of the world’s first standardised coins, and Croesus with the first coins of pure gold and pure silver. Before coins, every trade needed weighing and testing of metal; afterwards, anyone could count.
Lesson: money is a tool for exchange and measurement. What matters is not the metal or the paper but what it can reliably buy — which brings us to the next king.
Mansa Musa: too much gold
Mansa Musa ruled the Mali Empire in the 14th century, when West Africa produced much of the world’s gold. On his pilgrimage to Mecca in 1324 he travelled with a huge caravan and reportedly spent and gave away so much gold in Cairo that its value there fell for years afterwards.
Lesson: money is worth only what it can buy. When there is too much of it — or too many rupees chasing the same goods — prices rise. That is inflation, and it is why savings must earn more than inflation. At 6% a year, prices roughly double in 12 years; money kept idle for that long loses about half its buying power.
The Nizam of Hyderabad: rich but cash-poor
Mir Osman Ali Khan, the last Nizam of Hyderabad, appeared on the cover of Time in 1937 as the world’s richest man. He is said to have used the Jacob Diamond, of about 185 carats, as a paperweight, yet he was famous for frugal personal habits. Much of his wealth sat in jewels, land and palaces that could not easily be turned into cash.
Lesson: wealth that cannot become income or cash when you need it is of limited help. Liquidity matters. A family with a large house and no emergency fund is in the Nizam’s position on a small scale: rich on paper, short of cash when a hospital bill arrives.
John D. Rockefeller: the ledger habit
As a teenager in the 1850s, Rockefeller kept a small account book, which he called “Ledger A”, recording every cent he earned, spent and gave away. He kept the habit all his life and treasured the original book.
Lesson: the richest man of his age started by tracking small sums. Knowing where your money goes is step one of any plan. A simple monthly review — income, savings, the three biggest expenses — is today’s Ledger A.
Jamsetji Tata: wealth that keeps giving
A 2021 study by Hurun and the EdelGive Foundation ranked Jamsetji Tata as the world’s biggest philanthropist of the past century, with giving valued at more than US$100 billion. A large part of the Tata group is owned by charitable trusts, so its profits keep funding hospitals, research institutes and education.
Lesson: money placed in a well-run structure can serve a purpose for generations. Every family can build a small version with a will, nominees on every account and clear written goals.
Warren Buffett: time is the secret ingredient
Buffett bought his first share at the age of 11, yet about 99% of his fortune was made after his 50th birthday. His returns were excellent, but his real edge was decades of compounding without interruption: he never stopped, never sold everything in a panic and never needed the money.
Lesson: start early, stay invested and let time do the heavy lifting. Here is what a ₹10,000 monthly SIP becomes at an assumed 12% a year:
| After | Total invested | Value |
|---|---|---|
| 10 years | ₹12 lakh | about ₹22 lakh |
| 20 years | ₹24 lakh | about ₹92 lakh |
| 30 years | ₹36 lakh | about ₹3.1 crore |
The last ten years add more than the first twenty put together. That is the Buffett effect in rupees. These figures are illustrations at an assumed return, not a promise.
What the fortunes have in common
- Inflation is real: money left idle shrinks, as Cairo learnt from Mansa Musa.
- Liquidity is a form of safety: keep enough in cash-like form for emergencies, as the Nizam did not.
- Habits beat windfalls: Rockefeller’s ledger mattered more than any single deal.
- Structure outlives people: Jamsetji Tata planned beyond his own lifetime.
- Time multiplies everything: Buffett’s fortune came from decades of patience.
Frequently asked questions
Who was the richest person in history?
Nobody can say exactly, because wealth in different centuries cannot be compared precisely. Mansa Musa, Augustus Caesar, Akbar and John D. Rockefeller are often named, but the estimates are rough.
Can an ordinary family really use these lessons?
Yes — they work at any scale. Track your money, keep an emergency fund, invest regularly for decades and write a will. None of it needs a fortune to begin.
