Thugs and juggernauts share something; they are both words that come from Hindi words and enter English via the British occupation of what is now India. Now please excuse me while I indulge my love of words…
The Thuggee were a kind of bandit who specialised in killing travellers by strangulation, and the word comes from the Hindi for thief.
Juggernaut comes from jagannātha which is Hindi for ‘lord of the universe’ (a title for Krishna). It comes from the Rath Yatra festival where an idol of Krishna in a huge, ornate ‘wagon’ is pulled by hundreds of devotees.
Interestingly, for the British, the Thuggee were considered to be motivated by the worship of Kali (when in fact not all Thuggee were Hindus) and the idea that to murder for Kali saved lives by appeasing her and therefore stopping her destroying all of us. That’s one cool story.
Though, given juggernaut originally meant not only an unstoppable thing that might crush all in its path but that those crushed were a willing/necessary sacrifice, you get a sense that the British had a somewhat sensationalist view of Hinduism.
