One broad goal was effective national action. Congress needed reliable authority to raise revenue, regulate interstate and foreign commerce, provide for defense, and enact rules that did not depend entirely on voluntary state implementation. A separate executive could administer and enforce national law, while a federal judiciary could decide cases arising under that law. Supremacy gave valid federal law priority over conflicting state action. These mechanisms addressed the recurrent gap under the Articles between announcing a national decision and carrying it out.

Greater capacity produced concern about concentrated power. Bicameralism required two differently constituted chambers to agree. Separation of powers assigned legislative, executive, and judicial functions to different institutions, while checks gave each branch ways to resist the others. Federalism preserved state governments as political centers, and different terms and selection methods prevented every office from responding to the same electorate at the same moment. These devices did not eliminate self-interest or guarantee liberty, but they made control of the national government institutionally difficult to consolidate.

The design also reflected exclusions and bargains that must be judged directly. Women, enslaved people, Indigenous peoples, and many men lacked equal political participation. Slavery-related clauses protected human bondage and increased slaveholding power. Concern about governmental abuse coexisted with willingness to leave profound private and public domination in place. The final document was only a proposal until ratified, and Chapter 4 examines the arguments over whether its additional power and structural safeguards were acceptable. For Chapter 3, the durable model is capacity paired with restraint, shaped throughout by conflicts over representation and slavery.
