c. 1200, lode, lade "that which is laid upon a person or beast, burden," a sense extension from Old English lad "a way, a course, a carrying; a street, watercourse; maintenance, support," from Proto-Germanic *laitho (source also of Old High German leita, German leite, Old Norse leið "way, road, course"), from PIE root *leit- (2) "to go forth" (see lead (v.1)).
It seems to have expanded its range of senses in early Middle English, supplanting words based on lade (v.), to which it is not etymologically connected. The older senses went with the spelling lode (q.v.). The spelling is modern. Meaning "amount customarily loaded at one time" is from c. 1300; meaning "a quantity of strong drink taken" is from 1590s. Meaning "the charge of a firearm" is from 1690s.

Phrase take a load off (one's) feet "sit down, relax" is from 1914, American English. Get a load of "take a look at" is American English colloquial, attested from 1929.
late 15c., "to place in or on (a vehicle)," from load (n.). Sense of "add to the weight of, put a load in or on" is from c. 1500; sense of "to charge a firearm" is from 1620s.
