First-past-the-post voting is an electoral system wherein voters cast a vote for a single candidate, and the candidate with the most votes wins the election. Analogous systems for multi-winner contests are known as plurality block voting or "block voting" systems; both FPTP and block voting are "plurality" systems in that the winner needs only a plurality of the votes and not an absolute majority. The term first-past-the-post is a metaphor from horse racing of the plurality-voted candidate winning such a race; the electoral system is formally called single-member plurality voting (SMP) when used in single-member districts, and informally called choose-one voting in contrast to ranked voting or score voting.
Parallel voting is a type of mixed electoral system in which representatives are voted into a single chamber using two or more different systems, most often first-past-the-post voting (FPTP) with party-list proportional representation (PR). It is the most common form of mixed member majoritarian representation (MMM), which is why these terms are often used synonymously with each other. In some countries, parallel voting is known as the supplementary member (SM) system, while in academic literature it is sometimes called the superposition method within mixed systems.
The 1963 Italian general election was held on Sunday April 28. It was the first election with a fixed number of MPs to be elected, as decided by the second Constitutional Reform in February 1963. It was also the first election which saw the Secretary of Christian Democracy to refuse the office of Prime Minister after the vote, at least for six months, preferring to provisionally maintain his more influent post at the head of the party: this fact confirmed the transformation of Italian political system into a particracy, the secretaries of the parties having become more powerful than the Parliament and the Government.
The 1983 Italian general election was held in Italy on 26 June 1983. The Pentapartito formula, the governative alliance between five centrist parties, caused unexpected problems to Christian Democracy. The alliance was fixed and universal, extended both to the national government and to the local administrations. Considering that the election result did no longer depend on the strength of the DC, but the strength of the entire Pentapartito, centrist electors began to look at the Christian Democratic vote as not necessary to prevent a Communist success. Moreover, voting for one of the four minor parties of the alliance was seen as a form of moderate protest against the government without giving advantages to the PCI. Other minor effects of this election were a reduction of the referendarian Radical Party and the appearance of some regional forces.
The 1987 Italian general election was held in Italy on 14–15 June 1987. This election was the first Italian election in which the distance between the Christian Democrats and the Communists grew significantly instead of decreasing. Two parties that had not previously been in parliament won representation: the Greens with thirteen seats, and the Northern League with two.
The 1992 Italian general election was held on 5 and 6 April 1992. They were the first without the traditionally second most important political force in Italian politics, the Italian Communist Party (PCI), which had been disbanded in 1991. Most of its members split between the more democratic-socialist oriented Democratic Party of the Left (PDS), while a minority who did not want to renounce the communist tradition became the Communist Refoundation Party (PRC); however, between them they gained around 4% less than what the already declining PCI had obtained in the 1987 Italian general election, despite PRC absorbing the disbanded Proletarian Democracy (DP).
A majoritarian electoral system is an electoral system where the candidate with the most votes takes the seat using the winner-takes-all principle and in this way provides majoritarian representation. However, there are many electoral systems considered majoritarian based on different definitions, including types of at-large majoritarian representation such as block voting or party block voting, but district-based majoritarian systems such as first-past-the-post voting (FPTP/SMP). Where two candidates are in the running, the one with the most votes will have a majority, but where there are three or more candidates, it often happens that no candidate takes a majority of the votes.

A mixed electoral system or mixed-member electoral system combines methods of majoritarian and proportional representation (PR). The majoritarian component is usually first-past-the-post voting (FPTP/SMP), whereas the proportional component is most often based on party-list PR. The results of the combination may be mixed-member proportional (MMP), where the overall results of the elections are proportional, or mixed-member majoritarian, in which case the overall results are semi-proportional, retaining disproportionalities from the majoritarian component.

Mixed member majoritarian representation (MMM) is type of a mixed electoral system combining majoritarian and proportional methods, where the disproportional results of the majoritarian side of the system prevail over the proportional component. Mixed member majoritarian systems are therefore also as a type of semi-proportional representation, and are usually contrasted with mixed-member proportional representation (MMP) which aims to provide proportional representation via additional compensation ("top-up") seats.
