Explain why political machines thrived in urban areas with sizeable immigrant populations?

Political machines thrived in urban areas with sizeable immigrant populations because they provided essential services and support that newcomers often lacked, such as jobs, housing, and legal aid. These organizations capitalized on the immigrants' needs for integration and stability, offering assistance in exchange for votes and loyalty. Additionally, the machines often tapped into ethnic identities, fostering a sense of community and belonging among immigrants, which further solidified their political power. This reciprocal relationship helped political machines maintain control and influence in rapidly growing urban environments.
