- As cities grew in the late 1800s due to immigration, there was a greater need for public services like fire stations, police, sanitation, and infrastructure. However, city officials often misused public funds for personal gain through graft and corruption. - Political machines led by bosses dominated cities by creating networks to rig elections and ensure loyalty. While corrupt, bosses provided important social services to immigrants lacking other support. Immigrants strongly supported bosses in exchange for jobs and assistance. - Thomas Nast's political cartoons were influential in exposing corruption, like bringing down the powerful Tweed Ring in New York. His cartoons communicated effectively to immigrant communities with many illiterate residents.
