1570s, "to-draw up in chapters" (i.e., under "heads"), simply a back-formation from capitulation, to some extent from Medieval Latin capitulatus, past participle of capitulare "to-draw up in minds or chapters, arrange conditions." Usually of regards to surrender, hence indicating "to yield on stipulated terms" (1680s). Relevant: Capitulated; capitulating.
