Final answer:
Vlad II Dracul traveled to Edirne in 1442 primarily to negotiate a treaty, a common practice among European leaders of the time dealing with the expansion of the Ottoman Empire.
Step-by-step explanation:
Vlad II Dracul's journey to Edirne in 1442 was not for seeking asylum, a religious pilgrimage or vacation, but rather, it was primarily for negotiating a treaty. During this time, leaders often needed to secure alliances and agreements to maintain their power and protect their lands. Given the political climate and the Ottoman Empire's expansion, negotiating treaties would have been essential for leaders like Vlad II Dracul to ensure the security and stability of their territories. This kind of diplomatic activity was common among European nobility dealing with the rise of the Ottoman Empire, which had continuously sought to expand its territories and influence across the continent.
