The concept of " richest person in the world " has evolved dramatically over the last two centuries. In the 1820s, a net worth of a few million dollars was enough to claim the title. Today, top billionaires command fortunes in the hundreds of billions. For instance, Jeff Bezos was worth about $113 billion in 2020 – already unfathomable wealth – yet within just two years Elon Musk would surge past $300 billion, setting new records. And in early 2025, Elon’s net worth came extremely close to hitting a mind-numbing $500 billion.
This article takes a journey through the richest people from 1820 to the present, including a year-by-year breakdown from 2020 to 2025, and highlights notable figures who may have been overlooked. We’ll also share fun anecdotes and legacy facts about each person along the way.
