Another weird almost-AH thing from OTL, related to military uniforms. There's a now-ubiquitous item of clothing, more commonly associated with Western civilization, which actually originated in the Sikh Empire, having been commissioned by Claude Auguste Court in his appointed task of modernizing the Kingdom of the Punjab's artillery divisions as part of the new standard uniform which all of its gunners would wear. Relatively mass-producible, durable and hard-wearing uniforms were needed, so it was decided that they'd still be made from the coarse, thick calico cloth known as
Dungaree fabric, as before. However, since it was felt that these would lack sufficient regal poise to properly represent the wealth and bearing of the Sikh Raj (and the Napoleonic officers of the Fauj-i-Khas' 'French Regiment'), it was decided that the fabric for these uniforms would be woven using a 3/1 twill, and that the warp threads would be also dyed using the 'royal dye' of indigo (the primary export cash crop of its southern province of Multan).
These proved immensely successful, both with the troops and with the officers themselves. Feeling that the baggy, loose-fitting flannel or silk trousers typically worn by nobility in the Sikh Court was too soft for his tastes, Court adopted this new fabric for his own personal casual clothing, with General Ventura and several other members of the Fauj-i-Khas also following suit. And Jean-Baptiste Ventura, in particular, felt this type of clothing had great commercial potential, even more so than the Kashmiri shawls which were so in-vogue with the womenfolk when he'd brought them back with him on his diplomatic trip to London and Paris in 1838.
So much so that, even after being forced to depart the Punjab and return to Europe in late 1843 upon the dissolution of the Fauj-i-Khas, he decided to set up a major commercial enterprise producing this indigo-dyed, 3/1 twill-woven thick cotton fabric, in the primary metropolis of Bas-Languedoc, Nîmes. Unfortunately for Jean-Baptiste Ventura though, this textile venture proved far less lucrative and profitable than he'd hoped, especially with the raw materials needed to produce it entailing far higher expenses and overheads; gaining some local popularity, but failing to acquire the mass appeal farther afield which he'd hoped. As such, this commercial venture never managing to turn a profit, and wound up depleting much of the large fortune which he'd accumulated in the Sikh Raj.
However, even after his death in 1858, this textile factory and the fabric it produced, by then known as 'Serge de Nîmes' or in shorthand by the name of 'denim', still endured, having been bequeathed to his daughter Victorine (who'd been born in Lahore, and whose mother, Anna Moses, had an intriguing backstory of her own which isn't mentioned on wikipedia; not merely being 'of Armenian origin', but having been the daughter of one of the French officers in Begum Samru's army by his Armenian wife, with Victorine Ventura's aunt having also been the wife of Walter Dubuignon, Commander of Begum Samru's personal guard), along with the noble family she'd married into.
With Jean-Baptiste Ventura, the 'Count di Mandi', having become one of the most prominent generational role models for the European Jewish merchant community, it would be no surprise that the story of legendary adventures and exploits would spread even as far the Franconia region of the Kingdom of Bavaria in the German Confederation, from whence the Strauß family, one of its Jewish merchant families, would set sail across the Atlantic to establish dry goods businesses across America. And whilst the blue jeans craze which Ventura'd hoped to kickstart failed to materialize in France and across the rest of Europe during his own lifetime, it did wind up taking off in a big way over in the U.S of America.
If not for Court, Ventura, and the Sikh Fauj-i-Khas, this train of events would've almost certainly never happened; and blue jeans, along with all other items of denim clothing as we know them today IOTL, would almost certainly have never existed...
