I am sure that now it is better than before but not sure if it is absolutely correct despite the fact that I proposed it Serbian Despotovina officially ceased to exist after 1459 and Ottoman conquest but Vuk Grgurevi was soon granted with title of despot in exile ok but still despot and gained control of almost all Syrmia within Kingdom of Hungary There are sources that also name this territory as Serbian Despotovina despite it was province that was part of Kingdom of Hungary because it was ruled by despot who is Serbian territory was mainly populated by Serbs and intentionally stimulating Serbs from Ottoman empire to settle there free of tax for making military frontier against Ottomans There is no article about this despotovina but I think that if Elsie wrote that In 1485 at the death of her husband Angelina went to Serbia where her son had become a despot he could only mean this Serbian Despotovina within Kingdom of Hungary which need separate article I will try to learn more about it
