1980s - 2000 Movement which wanted to give more power to states

The movement you are referring to is known as the "devolution" movement. This movement sought to devolve power from the federal government to state governments, emphasizing the importance of local control and decision-making. It gained momentum in the 1980s and continued into the 2000s, with proponents arguing that states could better address the needs and preferences of their own populations. This movement was driven by a desire to reduce what some saw as an overly centralized federal government and to promote individual state sovereignty.
