Progressive Party being the two strongest parties. Minor parties in the 2021 legislature include the Puerto Rican Independence Party, Citizens' Victory Movement and Project Dignity. In Guam, the Popular Party was the only political party from 1949-1954, and was dominant until 1967 when they became affiliated with the Democrats. Since then, the Democrats and Republicans have been the two main parties. In the Northern Mariana Islands, the Democrats and Republicans are the two main parties but as recently as 2013, the Governor was a member of the Covenant Party. In American Samoa, the American Samoa Fono (territorial legislature) is non-partisan, and on ballots only candidate names are displayed, not political parties. The Governor has typically been either Democrat or Republican. In the US Virgin Islands, the Democrats and Republicans have been the main two parties, but two Governors during the 1970s were part of the Independent Citizens Movement, and from 2015-2019 the Governor was an independent. Australia House of Representatives Since the 1920s, the Australian House of Representatives (and thus the federal government) has in effect been a two-party system. Since the end of World War II, Australia's House of Representatives has been dominated by two factions: the centre-left Labor Party the centre-right Coalition. The Coalition has been in government about two-thirds of time, broken by four periods of Labor governments: 1972–1975, 1983–1996, 2007–2013 and 2022–present. The ALP is Australia's largest and oldest continuing political party, it was formed in 1891 from the Australian labour movement. The party has branches in every state and territory. The Coalition is a near-permanent alliance of several parties, primarily the Liberal Party of Australia (Australia's 2nd largest party) and National Party of Australia (4th largest). It was formed after the 1922 Australian federal election, when the Nationalist Party (ancestor of today's Liberal Party) lost its absolute majority, and was only able to remain in government by allying with the Country Party (now called the National Party). Under the Coalition agreement, if the Coalition forms government then the Prime Minister will be the leader of the Liberals, and the Deputy Prime Minister will be the leader of the Nationals. In theory, disagreements between the Coalition's constituent parties would lead to the Coalition being broken. However, the last time that this has happened at the federal level was in 1939-1940. One reason for Australia's two-party system is because the House of Representatives (which chooses the Prime
