Why it matters
The Constitution recast the revolutionary problem of sovereignty by creating a stronger federal government while embedding compromises over representation, federalism, and slavery that would shape the republic's future conflicts.
Why this provisional tier
This tier predates canonical assessment v1. It remains a research hypothesis and must not be used as settled label priority.
The proposed frame of government transformed the institutional settlement produced by independence and remains foundational to United States political authority.
Counterfactual test: Without the Philadelphia Constitution—or without its later ratification—the postwar union would have continued under the Articles or pursued a different federal settlement, altering the reach and structure of national power.
Signing did not make the Constitution operative. Ratification conventions, public argument, and the eventual accession of states did that work. The document also protected slavery through representation, fugitive-person, and migration clauses without using the word itself; constitutional achievement and coercive compromise belong in the same account.
