Etymology

It is Middle English relien, borrowed from Old French relier (“to fasten, attach, rally, bind together”),[2][3][4] from Latin religāre (“to fasten, bind fast”),[2][3][5] from re-, here perhaps intensive, and ligāre (“to bind”) (see ligament),[2][4][6] from PIE Proto-Indo-European *leyǵ- (“to tie, bind”).[4] It is a doublet of rally, from the same Old French verb.[7]

Earliest recorded meaning

To gather or assemble soldiers or followers, to rally: about 1330 in the OED,[8] before 1338 in Mannyng's Chronicle in Barnhart,[2] the mid-14th century in Etymonline.[4]

Semantic evolution

NODE and Word Origins trace the sense from gathering together to turning to or associating with someone, and so to depending on them with confidence.[6][9] To rally to or adhere to a person is from the 14th century,[3] to trust to a person or thing from 1571,[8] and to depend trustfully on someone or something from 1574 in Barnhart and the 1570s in Etymonline,[2][4] perhaps by way of the notion of rallying to or falling back on.[4] The usual construction with on may owe something to the unrelated verb lie, to rest.[4] The older senses are now obsolete.[4][8]
