This word was used by the Algonquin people to describe a meeting of tribal leaders, which was a precursor to modern political gatherings.
The term "caucus" entered the English language in the 18th century, specifically in the context of American politics. In 1770, a group of Bostonian colonists used the term to describe a meeting where they chose candidates for the Massachusetts legislature. This is considered the first recorded use of the word "caucus" in its current political context.
Since then, the word has evolved to describe a variety of political meetings and groups, ranging from small gatherings of like-minded individuals to large-scale events that shape national elections.
