To be on the warpath

Origin

The phrase conjures a vivid image from the history of Indigenous North American tribes. When a council decided on war, warriors would ritually prepare to embark on a specific 'warpath'—a designated route taken to surprise and engage an enemy tribe. This was no casual journey; it was a focused, determined, and often silent march, undertaken with a clear intent to battle. The powerful visual of warriors setting out, resolute and formidable, was readily absorbed into English lexicon by the 19th century, evolving into a metaphor to describe anyone fiercely angered and poised for a confrontation, ready to metaphorically 'battle' their opponent.
