The 34th New York State Legislature, consisting of the New York State Senate and the New York State Assembly, met from January 29 to April 9, 1811, during the fourth year of Daniel D. Tompkins's governorship, in Albany.

Under the provisions of the New York Constitution of 1777, amended by the Constitutional Convention of 1801, 32 Senators were elected on general tickets in the four senatorial districts for four-year terms. They were divided into four classes, and every year eight Senate seats came up for election. Assemblymen were elected countywide on general tickets to a one-year term, the whole Assembly being renewed annually.

In 1797, Albany was declared the State capital, and all subsequent Legislatures have been meeting there ever since. In 1799, the Legislature enacted that future Legislatures meet on the last Tuesday of January of each year unless called earlier by the governor.

At this time the politicians were divided into two opposing political parties: the Federalists and the Democratic-Republicans.^[1]

The State election was held from April 24 to 26, 1810. Gov. Daniel D. Tompkins and Lt. Gov. John Broome (both Dem.-Rep.) were re-elected.

Senator Nathan Smith (Western D.) was re-elected. Ebenezer White (Southern D.), Ex-Gov. Morgan Lewis, James W. Wilkin (both Middle D.), Henry Yates Jr. (Eastern D.), Reuben Humphrey, Philetus Swift and Henry A. Townsend (all three Western D.) were also elected to the Senate. All eight were Democratic-Republicans.

The Legislature met at the Old City Hall in Albany on January 29, 1811; and adjourned on April 9.

Nathan Sanford (Dem.-Rep.) was elected Speaker with 64 votes against 33 for Samuel A. Barker (Fed.). Samuel North (Dem.-Rep.) was elected Clerk of the Assembly with 64 votes against 37 for the incumbent James Van Ingen (Fed.). Sanford soon became ill, and could not attend the session anymore, and on February 12,^[2] William Ross (Dem.-Rep.) was elected Speaker for the remainder of the session with 65 votes against 24 for Barker (Fed.).

Lt. Gov. Broome died on August 8, 1810, leaving the presidency of the State Senate vacant. The senators elected John Tayler (Dem.-Rep.) as president pro tempore (vote: Tayler 21, Lewis 2, blank 2).

On January 30, the Dem.-Rep. Assembly majority elected a new Council of Appointment which removed almost all Federalist office-holders, most of whom had been appointed during the previous year.

At this session, the Legislature passed a bill incorporating the Mechanics and Farmers Bank of Albany, and Solomon Southwick became its first President.

On April 8, 1811, the Legislature appointed a new Erie Canal Commission to continue the planning and eventually the construction of the Erie Canal. The previous commissioners Gouverneur Morris, Stephen Van Rensselaer, William North, Thomas Eddy, State Senator DeWitt Clinton, Surveyor General Simeon DeWitt and Congressman Peter B. Porter were re-appointed; and Ex-Chancellor Robert R. Livingston and Robert Fulton, who were running a steamboat service between New York City and Albany, were added to the commission.
