Curious case of origins of Jeans

At the present time, it's difficult to find a person without a pair of Jeans as it is mainstream trousers worn across the globe. It's well known that it had humble origins with miners and working-class use for its durability and strength. However little is known about its journey to today's form starting from 17th century or even before that. Many nations have contributed to making it more versatile and popular over the centuries.

The thread pattern of Denim with blue outside and white inside originated at Genova in France.Before synthetic dying was invented in Germany in the 19th century Indigo plants from India were the source of blue color used for Jeans.

Denim has interesting origins in Dungaree a thick cotton textile from India that derives its name from a Dongri village near Mumbai. This thick cotton fabric was used by working classes like masons, blacksmiths, etc in India for centuries. British brought the fabric to Europe and it quickly became popular.

Even today in some parts of rural India Dungaree is used, in western Maharashtra, it is referred to as Dandaki. It's unique feature is pockets at abdomen level which are very handy to access while at work.

In the 17th Century Jeans became very common in the working classes in Italy and it was already very popular in France where it got its name. 

In America in 1873 copper-riveted pockets were patented by Levis Strauss and they added back pockets later in the early 20th century to get to the Jeans we know today. 

They also launched Overalls which was a big hit. In British English Overalls are called Dungarees which makes links it to its origins quite obvious. 

What is interesting is how international the story of Jeans is and the series of innovations in multiple countries over centuries has given us the Denim jeans that we all love.
