Conservatism
According to Alan Ware, Belgium, Denmark, Finland, France, Greece, Iceland, Luxembourg, Netherlands, Norway, Sweden, Switzerland and the United Kingdom retained viable conservative parties into the 1980s. Ware said that Australia, Germany, Israel, Italy, Japan, Malta, New Zealand, Spain and the United States had no conservative parties, although they had either Christian democrats or liberals as major right-wing parties. Canada, Ireland and Portugal had right-wing political parties that defied categorization: the Progressive Conservative Party of Canada; Fianna Fáil, Fine Gael and Progressive Democrats in Ireland; and the Social Democratic Party of Portugal. Since then, the Swiss People's Party has moved to the extreme right and is no longer considered to be conservative.
Left-wing politics
The term was later applied to a number of movements, especially republicanism during the French Revolution in the 18th century, followed by socialism, communism, anarchism and social democracy in the 19th and 20th centuries. Since then, the term left-wing has been applied to a broad range of movements including civil rights movements, feminist movements, anti-war movements and environmental movements, as well as a wide range of parties. According to former professor of economics Barry Clark, "[leftists] claim that human development flourishes when individuals engage in cooperative, mutually respectful relations that can thrive only when excessive differences in status, power, and wealth are eliminated".
