early 15c., populer, "public, commonly known," from Old French populaire and directly from Latin popularis "belonging to the people, general, common; devoted to or accepted by the people; democratic," from populus "people" (see people (n.)).
Meaning "of or pertaining to the people; depending on the people," especially the common people, is from 1540s. Meaning "suited to ordinary people, easily comprehended" is from 1570s in English; hence, of prices, "low, affordable to average persons" (1859).
The meaning "well-liked, admired by or enjoying the favor of the people" is attested from c. 1600. Of art, entertainment, etc., "favored by people generally" from 1819 (popular song).

Popular sovereignty, in U. S. hist., the theory that the right to decide whether slavery should exist in a territory rested with the people of that territory, and not with Congress. It was advocated especially by Democrats during the period 1847-61, and its leading champion was Douglas. It was often termed "squatter sovereignty," with which it was nearly identical. [Century Dictionary]
word-forming element used to make verbs, Middle English -isen, from Old French -iser/-izer, from Late Latin -izare, from Greek -izein, a verb-forming element denoting the doing of the noun or adjective to which it is attached.
The variation of -ize and -ise began in Old French and Middle English, perhaps aided by a few words (such as surprise, see below) where the ending is French or Latin, not Greek. With the classical revival, English partially reverted to the correct Greek -z- spelling from late 16c. But the 1694 edition of the authoritative French Academy dictionary standardized the spellings as -s-, which influenced English.
In Britain, despite the opposition to it (at least formerly) of OED, Encyclopaedia Britannica, the Times of London, and Fowler, -ise remains dominant. Fowler thinks this is to avoid the difficulty of remembering the short list of common words not from Greek which must be spelled with an -s- (such as advertise, devise, surprise). American English has always favored -ize. The spelling variation involves about 200 English verbs.
