Твртко I
Altomanović though was now in even more trouble. Prince Lazar Hrebeljanović of Serbia and Ban Tvrtko I of Bosnia allied themselves to defeat Nikola Altomanović. Desperate for a strong ally, Altomanović began negotiations with Đurađ. Most historians agree that in concluding negotiations, Đurađ gained the towns of Trebinje, Konavle and Dračevica from Altomanović, possibly a bribe to remain neutral within the war. Other historians, however, follow Mauro Orbini's account and argue that Đurađ never concluded such an agreement, rather conquered the towns he gained from the agreement himself after Altomanović was defeated in 1373.
