A maona ( ma‘ūnah; ; mu‘āwanah; ) also as mahona (pl. mahone) or societas comperarum was a medieval Italian association of investors formed to manage the purchased shares (loca or partes) of the revenue due to the relevant city-state through tax farming. The shares were individually sold to wealthy merchants who would band together to make collection easier.
