A faction is a group within a larger organization that disagrees with other members and may work against them. When a school's student council splits into factions, different groups might push competing ideas about how to spend the budget or what rules to change. Each faction believes it's right and tries to gain power or influence over the others.

Factions form when people have strong disagreements about important issues. In a book club, factions might emerge over whether to read fantasy or realistic fiction. In a political party, factions disagree about which policies matter most. The word carries a sense of conflict: factions don't just have different opinions, they actively compete with each other, sometimes putting their own goals ahead of the whole group's success.

History shows how powerful factions can be. America's Founding Fathers worried that factions could tear the young nation apart. James Madison wrote about the “mischiefs of faction” in The Federalist Papers, recognizing that while people naturally form groups around shared interests, these groups might hurt the common good while pursuing their own agendas.

When factions grow too strong, organizations can become paralyzed by internal fighting rather than working together toward shared goals.
