What is the state motto of Illinois?

The state motto of Illinois is "State sovereignty, national union." This phrase reflects the balance between state and federal authority, illustrating the principle that while Illinois maintains its own governance and autonomy (sovereignty), it is also part of a larger union with the other states in the United States. This motto captures the essence of federalism that is integral to the American system, highlighting the coexistence and interdependence of state and national interests.

The other choices present various ideals, but they do not represent the official state motto. "Liberty and Independence," for instance, conveys broader themes of freedom but lacks the specific reference to the relationship between the state and the nation. "Unity in Diversity" emphasizes social cohesion within a diverse population without mentioning governance structures. "Progress and Prosperity" is a positive aspiration but does not encapsulate the unique political philosophy concerning sovereignty and union that Illinois seeks to convey with its official motto.
