# 1886 Midterm Elections First-term [[Grover Cleveland]] administration midterm. Democrats lost House seats but retained majority; the **Haymarket Affair** (May 1886) had defined the year's labor-unrest political atmosphere; the **tariff debate** that would dominate the [[1888 Presidential Election]] was the central economic issue of the cycle. ## Result - **House:** Democrats lost ~16 seats but held majority (~169 of 325 Democrats vs. ~152 Republicans in the 50th Congress) - **Senate:** Republicans held narrow majority - **Chambers flipped:** None - **Net change:** Modest Democratic losses; party balance roughly held ## Notable - The **Haymarket Affair** (May 4, 1886, Chicago) — a bomb-throwing incident at a labor rally produced a police response that killed at least 7 officers and several civilians; the subsequent trial and execution of anarchist organizers became the defining American labor-political event of the 1880s - The **American Federation of Labor** was founded December 1886 - The **Interstate Commerce Act** (signed February 1887 by Cleveland) — the first major federal railroad regulation, prefiguring Progressive-Era regulatory architecture ## Connections - [[Grover Cleveland]] — Sitting president.
