in 1495, maria became involved in another legal dispute with ragusa, this time concerning the tribute of ston. the tribute had been paid by ragusa to serbian rulers since the reign of stefan dušan, but the income was ceded to the monastery of saint archangels michael and gabriel in jerusalem. mara reclaimed the income after the monastery was closed, and after her death it was managed by kantakouzene. maria decided to claim it as her aunts' legal heir, but the athonite monasteries of chilandar and saint paul's cited her aunts' non-formalized bequest. queen maria, described straightforwardly by the monks as an "evil woman", died 1500, when chilandar and saint paul's were recorded as having secured the income. she is believed to have died in çorlu and to have been buried in a local church along with her maternal uncle, manuel palaiologos.
