Which of the following was founded as the first national association representing municipalities, and provides advocacy support for cities, towns, and villages?

The National League of Cities (NLC) is indeed the first national association that was created to represent the interests of municipalities in the United States. Established in 1924, the NLC advocates for cities, towns, and villages at the federal level, providing support and resources aimed at enhancing the quality of life for residents in urban areas. Its mission includes lobbying for policies that benefit local governments, offering policy analysis, and fostering dialogue among municipal leaders.

This organization plays a crucial role in uniting various municipalities to address common challenges, share best practices, and gain access to collective resources, making it a foundational and significant entity in the landscape of municipal governance.
