In the book divergent how does the government work?

In "Divergent," the government is structured into five factions—Abnegation, Amity, Candor, Dauntless, and Erudite—each representing a different value and way of life. Citizens choose their faction upon reaching a certain age, which determines their role in society and how they contribute to the community. The factions operate independently but are interdependent, leading to tensions and conflicts, particularly between those who seek power and those who challenge the system. The rigid societal structure ultimately faces challenges from individuals who do not fit neatly into any faction, particularly the protagonist, Tris Prior, who is identified as Divergent.
