Washington, D.C. vs. Commonwealth States: Different Legal Foundations

What "Commonwealth State" Means

Four U.S. states officially style themselves Commonwealths: Kentucky, Massachusetts, Pennsylvania, Virginia. Historically, they were British colonies that became states—the term reflects popular sovereignty (from "common weal"). Legally, they are identical to other states under the Constitution.

D.C.’s Unique Status

• Not a state — federal district under Article I, Section 8, Clause 17.
• Created by District of Columbia Organic Act of 1801 from MD/VA land.
• Home Rule Act (1973) — elected mayor, 13-member Council; but Congress retains veto power over laws, controls budget, courts.
• No voting representation in Congress (1 non-voting Delegate).
• Federal law applies directly; D.C. Code is local law subject to Congressional review.

Key Legal Differences

Commonwealth of Puerto Rico & USVI

Also "commonwealths" but territories — not states. Different from the four states.

Bottom line: D.C. is not a state, not a commonwealth state, and does not share their legal autonomy.
