libertarian

Etymology

It is formed from English liberty + -arian,^{[2][3][4][5][6]} on the model of unitarian and similar words.^[7][3][8][9] Liberty is from Old French liberte (“freedom, free will”), from Latin lībertās (“freedom, the condition of a free man”), from līber (“free”).^[10][4] For the political senses the OED compares French libertaire, recorded in French as a noun from 1858 and as an adjective from 1901.^[2]

Earliest recorded meaning

In philosophy, a person who holds that human beings have free will, as opposed to a necessitarian or determinist: 1789, in William Belsham's Essays.^[2][7][3]

Semantic evolution

The word began in the debate on free will and necessity, and this sense is still current in philosophy.^[2][7][11] From 1796 it was also used of anyone who advocates or defends liberty, especially in political and social life;^[2] Etymonline and Barnhart date this broader sense, liberty in thought and conduct, only from 1878.^[7][3] The adjective followed, first in the free-will sense (1803) and then in political contexts (1896);^[2] Etymonline has it by 1882.^[7] In the 1940s, in the United States, the word came to name the supporters of a political philosophy that puts individual rights first and wants as little government as possible.^[2][10] The Libertarian Party of the United States was founded in Colorado in 1971.^[7][6] The derivative libertarianism is recorded in religion from 1849 and in politics from 1901.^[7]
