1870–71 United States House of Representatives elections
House elections for the 42nd U.S. Congress

The 1870–71 United States House of Representatives elections were held on various dates in various states between June 6, 1870, and October 6, 1871. Each state set its own date for its elections to the House of Representatives before or after the first session of the 42nd United States Congress convened on March 4, 1871. They occurred in the middle of President Ulysses S. Grant's first term. Elections were held for all 243 seats, representing 37 states.
With Grant's administration rocked by a number of scandals (including a shady deal for gold speculation that led to a crash in the market and several business deals that saw highranking governmental officials gain kickbacks) and Reconstruction winding down, his Republican Party lost seats to the opposition Democratic Party but retained an overall majority. Also, since white-supremacist governments controlled by the Democratic Party were reestablishing themselves in some portions of the Southern United States, the Democrats were able to make huge gains in this election.

Election dates
In 1845, Congress passed a law providing for a uniform nationwide date for choosing Presidential electors. This law did not affect election dates for Congress, which remained within the jurisdiction of State governments, but over time, the States moved their congressional elections to this date as well. In 1870, there remained 12 States that held elections before Election Day, and 4 that held it after at this time:

Why this record matters
The phrase “house elections for the 42nd U.S. Congress” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 26, 2026. The linked authority identifier is Q4450548. The first chronological checks are 1870, 1871, 1845 and 1869.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
