The Day Pittsburgh Swallowed an Entire City
Steel City Stories · Chapter 35
Before there was a Pittsburgh North Side, there was Allegheny City: an independent municipality with its own mayor, councils, departments, debts and civic identity. By the 1900 census it contained nearly 130,000 people.
The consolidation law did not give Allegheny an independent veto. Ballots across the proposed Greater Pittsburgh territory were combined. Allegheny voters rejected consolidation, but Pittsburgh’s larger pro-consolidation vote overwhelmed that opposition in the total.
Opponents fought through the courts. In Hunter v. City of Pittsburgh, 207 U.S. 161 (1907), the U.S. Supreme Court upheld the consolidation and articulated the powerful principle that municipalities are political subdivisions subject to broad state authority over their boundaries and powers.
No houses moved. The river stayed where it was. The government disappeared. Allegheny became the North Side, while its lawsuit became a lasting precedent in American local-government law.
