Blue jeans, as we know them today, were invented in 1873 when Levi Strauss and Jacob Davis received a U.S. patent for riveted work pants made from denim.

Core invention date

  • On May 20, 1873, Levi Strauss and Jacob Davis were granted a patent for using metal rivets at stress points (like pockets and seams) on sturdy work trousers.
  • This riveted denim workwear is widely regarded as the “birthday” of blue jeans because it transformed existing denim pants into the durable garment that would become modern jeans.

Before 1873: the fabric

  • Tough twill fabrics similar to denim and “jean” cloth were already produced in European textile centers such as Genoa (Italy) and NĂźmes (France) centuries earlier, and were used for durable work clothing.
  • The term “jeans” likely derives from the French name for Genoa, “GĂȘnes,” while “denim” is associated with serge de NĂźmes (“cloth from NĂźmes”), showing the European roots of the fabric itself.

Why 1873 is the key year

  • Denim trousers existed before, but the combination of riveted construction and blue denim fabric in the patented design created a new category of extra‑durable work pants for miners and laborers, later known as blue jeans.
  • Because of this, historians and Levi Strauss & Co. alike generally treat 1873—specifically May 20—as the moment blue jeans were truly “invented,” even though the underlying fabrics and work pants predated that year.
