The 115th New York State Legislature, consisting of the New York State Senate and the New York State Assembly, met from January 5 to April 26, 1892, during the first year of Roswell P. Flower's governorship, in Albany.

Under the provisions of the New York Constitution of 1846, 32 Senators and 128 assemblymen were elected in single-seat districts; senators for a two-year term, assemblymen for a one-year term. The senatorial districts were made up of entire counties, except New York County (seven districts) and Kings County (three districts). The Assembly districts were made up of entire towns, or city wards, forming a contiguous area, all within the same county.

At this time there were two major political parties: the Democratic Party and the Republican Party. In New York City, the Democrats were split into three factions: Tammany Hall, the "County Democracy" and the "New York Democracy". The Prohibition Party and the Socialist Labor Party also nominated tickets.

The New York state election, 1891 was held on November 3. Roswell P. Flower was elected Governor; and Speaker William F. Sheehan was elected Lieutenant Governor, both Democrats. The other five statewide elective offices up for election were also carried by the Democrats. The approximate party strength at this election, as expressed by the vote for Governor, was: Democratic 585,000; Republican 535,000; Prohibition 30,000; and Socialist Labor 15,000.

This was the first time that seats in the Legislature were contested in the courts. Previously, since Independence in 1777, seats could be contested only in the Legislature, after the beginning of the session, and it took usually a long time to come to a conclusion. Most contestants whose claims were found to be correct, were seated only a few days before the end of the session. Now it became possible to take the contest to the courts, swiftly being decided by New York Court of Appeals, before the session began. At this time, the Court of Appeals was composed of five Democrats and two Republicans, and ruled in favor of Democrats Edward B. Osborne, John A. Nichols and Charles E. Walker who were referred to in the press as "usurpers", holding their seats by fraud. Seven more seats were then contested in the Legislature.
