Lincolnshire (UK Parliament constituency)

The constituency consisted of the historic county of Lincolnshire, excluding the city of Lincoln which had the status of a county in itself after 1409. (Although Lincolnshire contained four other boroughs, Boston, Grantham, Great Grimsby and Stamford, each of which elected two MPs in its own right for part of the period when Lincolnshire was a constituency, these were not excluded from the county constituency, and owning property within the borough could confer a vote at the county election. This was not the case, though, for Lincoln.)

As in other county constituencies the franchise between 1430 and 1832 was defined by the Forty Shilling Freeholder Act, which gave the right to vote to every man who possessed freehold property within the county valued at £2 or more per year for the purposes of land tax; it was not necessary for the freeholder to occupy his land, nor even in later years to be resident in the county at all.

Except during the period of the Commonwealth, Lincolnshire has two MPs, traditionally referred to as Knights of the Shire, elected by the bloc vote method, under which each voter had two votes. In the nominated Barebones Parliament, five members represented Lincolnshire. In the First and Second Parliaments of Oliver Cromwell's Protectorate, however, there was a general redistribution of seats and Lincolnshire elected ten members, while each of the boroughs apart from Lincoln had their representation reduced to a single MP. The traditional arrangements were restored from 1659.

At the time of the Great Reform Act in 1832, Lincolnshire had a population of approximately 317,000, though only 5,391 electors voted at the last contested election, a by-election in 1823.

Elections were held at a single polling place, Lincoln, and voters from the rest of the county had to travel to the county town to exercise their franchise. It was normal for voters to expect the candidates for whom they voted to meet their expenses in travelling to the poll, making the cost of a contested election substantial. Contested elections were therefore rare, potential candidates preferring to canvass support beforehand and usually not insisting on a vote being taken unless they were confident of winning; at all but 4 of the 29 general elections between 1701 and 1832, Lincolnshire's two MPs were elected unopposed.

The constituency was abolished in 1832 by the Great Reform Act, being divided into two two-member county divisions, Northern Lincolnshire (or The Parts of Lindsey) and Southern Lincolnshire (or The Parts of Kesteven and Holland).
