  A two-party system is a political structure characterized by the dominance of two major political parties that compete for power, typically alternating control of government through elections. The origins of this system can be traced back to eighteenth-century Europe and it has been adopted in various forms across different countries, notably in the United States and the United Kingdom.

  two-party system, political system in which the electorate gives its votes largely to only two major parties and in which one or the other party can win a majority in the legislature. The United States is the classic example of a nation with a two-party system. The contrasts between two-party and multiparty systems are often exaggerated. Within each major party in the United States, the Republicans and the Democrats, many factions are struggling for power. The presence of divergent interests [...] The two-party system moderates the animosities of political strife. To appeal for the support of a majority of voters, a party must present a program sympathetic to the desires of most of the politically active elements of the population. In the formulation of such a program an effort must be made to reconcile the conflicting interests of different sectors of the population. This enables the party, if expedient, to resist demands that it commit itself without reservation to the policies urged [...] The two-party system is said to promote governmental stability because a single party can win a majority in the parliament and govern. In a multiparty country, on the other hand, the formation of a government depends on the maintenance of a coalition of parties with enough total strength to form a parliamentary majority.

  The Two-Party System and the Two Major Parties The electoral system in the U.S. is called a two-party system. That means that two parties dominate the political field in all three levels of government. In the U.S. these two parties are the Republican Party and the Democratic Party. Other parties, often generally termed “third parties”, in the U.S. include The Green Party, Libertarians, Constitution Party and Natural Law Party. [...] One advantage of having a two-party system is that it helps ensure that the two main parties in power have a wide platform that represents the general public. Because the two parties are so large, there is room for a wide range of political positions within each party. This means that there may exist slightly varying political viewpoints on different matters within each party. A Broad Political Spectrum

A two-party system is a political party system in which two major political parties consistently dominate the political landscape. At any point in time, one of the two parties typically holds a majority in the legislature and is usually referred to as the majority or governing party while the other is the minority or opposition party. Around the world, the term has different meanings. For example, in the United States, the Bahamas, Jamaica, United Kingdom and Zimbabwe, the sense of two-party system describes an arrangement in which all or nearly all elected officials belong to either of the two major parties, and third parties rarely win any seats in the legislature. In such arrangements, two-party systems are thought to result from several factors, like "winner takes all" or "first past the post" election systems. In such systems, while chances for third-party candidates winning election to major national office are remote, it is possible for groups within the larger parties, or in opposition to one or both of them, to exert influence on the two major parties. In contrast, in Canada, the United Kingdom and Australia and in other parliamentary systems and elsewhere, the term two-party system is sometimes used to indicate an arrangement in which two major parties dominate elections but in which there are viable third parties that do win some seats in the legislature, and in which the two major parties exert proportionately greater influence than their percentage of votes would suggest. Explanations for why a political system with free elections may evolve into a two-party system have been debated. A leading theory, referred to as Duverger's law, states that two parties are a natural result of a winner-take-all voting system.
