Cities and towns are creatures of the state. There is a constitutional hierarchy between levels of governments, and cities and local governments are structurally at the bottom of this hierarchy. However, despite this established dynamic of power, local governments in the State of Arizona have traditionally maintained a significant level of autonomy when it comes to enacting their own policies. In the face of slow-moving state and national governments, local governments have operated on a level that is quick to respond to the needs of its citizens, and cities have assumed the role of filling in the policy and administrative gaps of higher levels of government. However, relatively recently, there has been increased conflict between cities and the State of Arizona. The state legislature has passed various measures restricting local governments on a variety of topics ranging from elections, labor, firearms, immigration, environmental regulations, and more, preempting cities at a wide level.
