late 14c., "relation of incidents" (true or false), from Old French estoire, estorie "story; chronicle, history" (12c., Modern French histoire), from Latin historia "narrative of past events, account, tale, story," from Greek historia "a learning or knowing by inquiry; an account of one's inquiries; knowledge, account, historical account, record, narrative," from historein "be witness or expert; give testimony, recount; find out, search, inquire," and histōr "knowing, expert; witness," both ultimately from PIE *wid-tor-, from root *weid- "to see," hence "to know."
It is thus related to Greek idein "to see," and to eidenai "to know." Beekes writes of histōr that "The word itself, but especially the derivations ... that arose in Ionic, have spread over the Hellenic and Hellenistic world together with Ionic science and philosophy."
In Middle English, not differentiated from story (n.1); sense of "narrative record of past events" probably first attested late 15c. Meaning "the recorded events of the past" is from late 15c. As a branch of knowledge, from late 15c. Meaning "a historical play or drama" is from 1590s. Sense of "systematic account (without reference to time) of a set of natural phenomena" (1560s) is now obsolete except in natural history (as late as the 1880s published county histories in the U.S. routinely included natural history chapters, with lists of birds and fishes and illustrations of local slugs and freshwater clams). Meaning "an eventful career, a past worthy of note" (a woman with a history) is from 1852. To make history "be notably engaged in public events" is from 1862.
History is the interpretation of the significance that the past has for us. [Johan Huizinga, "The Task of the Cultural Historian"]
History is more or less bunk [Henry Ford, Chicago Tribune, May 25, 1916]
One difference between history and imaginative literature ... is that history neither anticipates nor satisfies our curiosity, whereas literature does. [Guy Davenport, "Wheel Ruts," 1996]
Old English life (dative lif) "animated corporeal existence; lifetime, period between birth and death; the history of an individual from birth to death, written account of a person's life; way of life (good or bad); condition of being a living thing, opposite of death; spiritual existence imparted by God, through Christ, to the believer," from Proto-Germanic *leiban (source also of Old Norse lif "life, body," Old Frisian, Old Saxon lif "life, person, body," Dutch lijf "body," Old High German lib "life," German Leib "body"), properly "continuance, perseverance," from PIE root *leip- "to stick, adhere."
The noun associated with live (v.) "to live," which is literally "to continue, remain." Extended 1703 to inanimate objects, "term of duration or existence." Sense of "vitality, energy in action, expression, etc." is from 1580s. Meaning "conspicuously active part of human existence, pleasures or pursuits of the world or society" is by 1770s. Meaning "cause or source of living" led to the sense "vivifying or animating principle," and thus "one who keeps things lively" in life of the party (1787). Meaning "imprisonment for life, a life sentence" is from 1903. Paired alliteratively with limb from 1640s. Not on your life "by no means" is attested from 1896.
In gaming, an additional turn at play for a character; this transferred use was prefigured by uses in card-playing (1806), billiards (1856), etc., in reference to a certain number of chances or required objects without which one's turn at the game fails. The life "the living form or model, semblance" is from 1590s. Life-and-death "of dire importance" is from 1822; life-or-death (adj.) is from 1897. Life-jacket is from 1840; life-preserver from 1630s of anything that is meant to save a life, 1803 of devices worn to prevent drowning. Life-saver is from 1883, figurative use from 1909, as a brand of hard sugar candy from 1912, so called for shape.

Life-work "the labor to which one's life has been devoted" is from 1848. Expression this is the life is from 1919; verbal shrug that's life is from 1924 (earlier such is life, 1778).
"life at ease," by 1902 (as Reilly), popularized in U.S. during World War I; it seems to have been military slang initially, sometimes said to trace to various songs but none of that title has been found.
"opposed to abortion," attested by 1976, from pro- + life. Used earlier in a more general sense of "enhancing life." Hostile alternative anti-choice is attested by 1978 in Ms. magazine (compare pro-choice).
What hypocrisy to call such anti-humanitarian people 'pro-life.' Call them what they are — antichoice. [Ms., Oct. 8, 1978]
