Politics of the Principality of Wallachia

Timeline

1. 1371–1377Câmpulung · WallachiaVladislav I Vlaicu (Basarab dynasty) consolidated his rule over Wallachia in the early 1370s, submitting to King Louis I of Hungary in exchange for recognition of suzerainty. He built defenses, reorganized the local nobility, and repelled Bulgarian and early Ottoman raids on the south bank of the Danube, maintaining the principality's role as Hungary's southeastern bulwark.
2. 1377–1378Wallachia · RomaniaAfter Vladislav I died in 1377, his brother Radu I succeeded as voivode. Radu I continued the policy of vassalage to Hungary while maintaining contacts with Transylvanian nobles. Although the dynastic succession was smooth, the influence of local boyar factions rose during the change of voivodes.
3. 1375–1380Lower Danube · RomaniaIn the late 1370s Ottoman forces pushed north along the Danube, making coordinated defense with Hungary ever more important. Radu I sought survival among multiple powers through tribute, marriage alliances, and military action; though the principality retained nominal independence, its military and diplomatic dependence on Hungary deepened, foreshadowing the fiercer Ottoman–Wallachian conflicts of the late 14th century.
