1830–31 United States Senate elections
1830, 1831 US Senate elections

The 1830–31 United States Senate elections were held on various dates in various states. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1830 and 1831, and a seat may have been filled months late or remained vacant due to legislative deadlock. In these elections, terms were up for the senators in Class 3.
The Jacksonians gained one seat from the Anti-Jacksonian coalition, but lost one seat to the short-lived Nullifier Party. By the time Congress first met in December 1831, however, the Jacksonians had a net loss of one seat.

This brief starts where responsible research should: with the source description of “1830–31 United States Senate elections” as 1830, 1831 US Senate elections. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 1830, 1831 US Senate elections. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 12, 2026. The linked authority identifier is Q1150164. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1830, 1913, 1831 and 1833.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
