[1] His reign was marked by efforts to maintain control of his territories amidst increasing Ottoman pressure and internal rivalries with other Albanian noble families.

Gjergj allied with Venice to protect Durrës but ultimately relinquished the city to Venetian rule due to declining health and political instability.

Gjergj's death in 1392 marked the end of his lineage, with his holdings passing to his sister, Helena Thopia, and his legacy shaped by his alliances and resistance to Ottoman encroachment.

[2][3][4][5] A member of the powerful Thopia family, Karl ruled the Principality of Albania on the coast of the Adriatic Sea and played a significant role in regional politics.

[1] Once Ottoman forces began conquering areas previously held by local lords, the Venetian Senate reassessed Albania's strategic importance.

[11] The speakers emphasized the considerable investments Venice had made in protecting the city and warned of the severe consequences if Durrës fell into Ottoman hands.

[11] A detailed plan was proposed, instructing Captain Saraceno Dandolo to meet with Gjergj Thopia, assure him of Venice's support, and secure Durrës castle with Venetian expenses.

[13] A detailed entry from this council session highlighted Venice's authoritative involvement in managing the situation, marking a significant shift in Thopia's status.

[22] Antonio Contarini, a maritime expert, proposed a plan that ultimately prevailed, allowing for a more inclusive approach to repopulating the city and addressing the effects of Gjergj's past actions.

[23][24][25] Progon Dukagjini, who was Gjergj Thopia's brother-in-law through his sister Voisava, presented several petitions on behalf of himself and his wife during his visit to Venice in August 1393.

[26] Out of the ten requests, one included the return of precious items once belonging to Gjergj Thopia, which were held by the commune, likely made on behalf of his sister, Voisava.
