Origin and history of public

c. 1300, peple, "humans, persons in general, men and women," from Anglo-French peple, people, Old French pople, peupel "people, population, crowd; mankind, humanity," from Latin populus "a people, nation; body of citizens; a multitude, crowd, throng," a word of unknown origin. Based on Italic cognates and derivatives such as populari "to lay waste, ravage, plunder, pillage," Populonia, a surname of Juno, literally "she who protects against devastation," the Proto-Italic root is said to mean "army" [de Vaan]. An Etruscan origin also has been proposed. The Latin word also is the source of Spanish pueblo, Italian popolo.

In English, it displaced native folk, also early Middle English thede, from Old English þeod "people, race, nation" (from PIE root *teuta- "tribe"). Thede lingered in the conventional expression in thede "among people" (attested to c. 1400), and in the first element of place-names Thedford, Thetford, etc. Also compare Middle English thedish "native or belonging to a (particular) land," from Old English þeodisc.

The sense of "some unspecified persons" is from c. 1300. The meaning "body of persons comprising a community" is by mid-14c. (late 13c. in Anglo-French); the meaning "common people, masses" (as distinguished from the nobility) is from late 13c. The meaning "members of one's family, tribe, or clan" is from late 14c.

The word was adopted after c. 1920 by Communist totalitarian states, according to their opponents to give a spurious sense of populism to their governments. It is based on the political sense of the word, "the whole body of enfranchised citizens" (considered as the sovereign source of government power), attested from 1640s. This also is the sense in the legal phrase The People vs., in U.S. cases of prosecution under certain laws (1801).

The people are the only censors of their governors: and even their errors will tend to keep these to the true principles of their institution. To punish these errors too severely would be to suppress the only safeguard of the public liberty. The way to prevent these irregular interpositions of the people is to give them full information of their affairs thro’ the channel of the public papers, and to contrive that those papers should penetrate the whole mass of the people. [Jefferson to Edward Carrington, Jan. 16, 1787]

People of the Book "those whose religion entails adherence to a book of divine revelation" (1834) translates Arabic Ahl al-Kitab.

1859, slang shortening of public house (see public (adj.)), which meant originally "any building open to the public" (1570s), then "inn that provides food and is licensed to sell ale, wine, and spirits" (1660s), and then "tavern" (1768).

Simple public (n.) as short for public house is attested from 1709 and might have been the intermediate form. Pub crawl is attested by 1910 in British slang. Pub rock is from 1973 in England; popular in U.S. from 1976.

When, in the late '60s, rock 'n' roll suddenly became rock, there sprang up a network of bands that sought to preserve the old styles, that resisted the trend toward larger and larger concert halls. Because these groups preferred to play one-nighters on Britain's club circuit, their music came to be known as "pub rock."
