Medieval Dynastic and Political Ties: Wallachia and Serbia:
A Union of Thrones
In the fourteenth century, when medieval Europe’s power struggles rippled across the Balkans, Wallachia and Serbia stood as neighboring strongholds of the Orthodox world. Their rulers navigated a maze of shifting allegiances, imperial ambitions, and the relentless advance of the Ottomans. In such a world, alliances were often sealed at the altar rather than the treaty table, weaving dynastic threads between thrones and across borders. The Basarab princes of Wallachia and the Nemanjić and Branković rulers of Serbia bound their courts through marriage, faith, and shared purpose. Beyond the politics of the day, these ties fostered a cultural and spiritual fraternity — strengthened by military cooperation and shaped by the grandeur of Byzantine tradition — that allowed both realms to stand, for a time, as united guardians of their heritage in an age of uncertainty.
The Marriage of Stefan Uroš V and Anna of Wallachia (1360)
One of the most significant Wallachian–Serbian dynastic links was the union of Stefan Uroš V (r. 1355–1371) and Anna (Anca) of Wallachia around 1360. Known in history as “Uroš the Weak,” the Serbian ruler was the only son of Tsar Stefan Dušan and Helena of Bulgaria. He inherited a vast but fragile empire, increasingly threatened by the ambitions of powerful nobles. In this unstable political climate, securing alliances through marriage was a strategic necessity.
Anna was a princess of the Basarab dynasty, daughter of Voivode Nicolae Alexandru of Wallachia. Her family had already asserted the principality’s autonomy under her grandfather Basarab I and had cultivated alliances with neighboring Orthodox realms. The Basarabs also maintained close connections with the Bulgarian court — Anna’s aunt Theodora married Tsar Ivan Alexander of Bulgaria, and her sister wed Tsar Ivan Stratsimir of Vidin. Anna’s marriage to Uroš extended these connections into Serbia, cementing Wallachia’s role in Balkan diplomacy.
The marriage elevated Anna to Empress consort of Serbia and symbolically united the Nemanjić and Basarab dynasties. For Serbia, the match offered a potential ally to the north against both Hungary and the encroaching Ottomans. For Wallachia, it brought prestige and the possibility of military backing from the Serbian court. Both realms were Orthodox Christian states, making the union politically and culturally harmonious.
Although the marriage’s immediate political impact was limited, it did formalize a period of cordial relations. In 1369, Anna’s half-brother, Prince Vladislav I of Wallachia, led forces to assist their Bulgarian kin, Ivan Stratsimir, in regaining Vidin from Hungarian occupation — a demonstration of how family alliances could translate into military support. A similar expectation may have existed between Wallachia and Serbia, but Uroš’s domestic troubles left little opportunity for coordinated action.
The marriage produced no known heirs, and with Uroš’s death in 1371 the Nemanjić dynasty came to an end. Anna, remembered as the last Serbian Empress, withdrew from public life, taking monastic vows under the name Jelena. Her story stands as a symbol of a moment when Wallachia and Serbia’s fates briefly converged at the highest level of state and family

Broader Dynastic Ties in the 13th–15th Centuries
The Uroš–Anna union was part of a broader pattern of intermarriage and kinship between the ruling houses of Wallachia and Serbia.
• Wallachia’s Basarab Dynasty and the Balkans: Before forging ties with Serbia, the Basarabs secured strong connections with Bulgaria. In the 1330s, Voivode Basarab I allied with Bulgaria against Hungary and Byzantium, marrying his daughter Theodora to Tsar Ivan Alexander. Through this link, Ivan Alexander’s sister Helena married Tsar Stefan Dušan of Serbia, making the Serbian imperial family indirectly connected to Wallachia.
• Later Marriages with Serbian Nobility: A prominent example is the marriage of Prince Neagoe Basarab of Wallachia (r. 1512–1521) to Princess Milica Despina of the Branković dynasty, a descendant of the Lazarević line. Their union brought Serbian influence into the Wallachian court, with Milica acting as a patron of Orthodox institutions and even serving as regent after her husband’s death. Through her, Serbian royal lineage continued in Wallachia, symbolizing a shared resistance to Ottoman dominance.
• Informal and Indirect Ties: Beyond formal unions, Serbian nobles and clergy often sought refuge in Wallachia after the fall of Serbia to the Ottomans. Some Wallachian boyar families claimed Serbian roots, while military cooperation was frequent. Voivode Mircea the Elder allied with Prince Lazar of Serbia in resisting Ottoman advances, and later campaigns — such as the Crusade of Nicopolis (1396) and the Long Campaign (1443–1444) — saw Wallachian and Serbian forces fighting alongside each other, often under Hungarian leadership.
Faith, Culture, and the Byzantine Legacy
Dynastic marriages between Wallachia and Serbia did not stand in isolation — they were strengthened by a shared religious foundation and a cultural language that both courts instinctively understood. Each principality stood firmly within the Orthodox Christian sphere, guided by the rites and authority of the Church and linked to the wider “Byzantine Commonwealth” that spanned the Eastern Mediterranean and the Balkans. This shared faith was not merely spiritual; it shaped diplomacy, law, ceremony, and the very identity of the ruling houses. Ecclesiastical ties ran deep: metropolitans and bishops moved between the two realms, bringing not only blessings but also political counsel, while donations to monasteries often carried the weight of diplomatic gifts.
The courts of Târgoviște and Kruševac — later Smederevo — mirrored one another in ceremonial life. Byzantine etiquette dictated how envoys were received, how rulers appeared in public, and how authority was expressed through clothing, titles, and processions. Wallachian voivodes adopted honorifics and court ranks modeled on Constantinople’s imperial hierarchy, just as Serbian rulers had done since the height of the Nemanjić dynasty. This ceremonial resemblance meant that an emissary or bride traveling from one court to the other stepped into a familiar world, where the political theatre of rulership followed the same script.
Art and architecture further bound the two lands together. The monastic style perfected in Serbia — a blend of Byzantine architectural plans with local stonework traditions — left a visible mark in Wallachia. For example, the Princely Church of Curtea de Argeș displays decorative stone carvings and facade arcading reminiscent of Serbian monasteries such as Studenica and Gračanica. Conversely, Wallachian rulers returned the gesture through patronage. The famous Hilandar Monastery on Mount Athos, a spiritual beacon of the Serbian Church, received generous donations from Wallachian princes like Neagoe Basarab, who sent funds, vestments, and liturgical vessels.
Monastic and artistic exchanges flowed in both directions. Serbian iconographers such as those trained at Resava Monastery (Manasija) were employed in Wallachia to paint frescoes in the Serbo-Byzantine style — characterized by rich, saturated pigments, elongated saintly figures, and architectural backdrops inspired by Constantinople. Wallachian scribes, in turn, produced illuminated manuscripts in Church Slavonic that were sent to Serbian monasteries, including Ravanica and Krušedol, sometimes as diplomatic gifts. Notable examples include gospel books bound in gilded covers, gifted during the reign of Vladislav II.
Even smaller-scale exchanges carried symbolic weight. The Craiovești family of Wallachia, connected by marriage and political alliances to exiled Serbian nobility, commissioned reliquary crosses from Serbian goldsmiths. Serbian monks fleeing Ottoman advances often settled in Wallachian monasteries like Cozia or Snagov, bringing with them relics, miracle-working icons, and even liturgical melodies that would influence local chant traditions.
Through this constant interplay of faith, art, and ceremony, dynastic marriages gained a deeper context. They were not just political arrangements, but unions woven into a living tapestry of shared belief and mutual cultural heritage — a tapestry that, for generations, helped Wallachia and Serbia see themselves as partners in defending and preserving the Orthodox way of life in a turbulent world.
From the Middle Ages to Modern Friendship
Although medieval Serbia eventually succumbed to Ottoman conquest and Wallachia entered a long period as an Ottoman vassal, the legacy of their close ties survived the centuries. The memory of shared struggles, dynastic bonds, and Orthodox solidarity formed a quiet undercurrent in their political identities.
By the 19th century, both states re-emerged as central players in the Balkans’ struggle for independence. Serbia, under leaders such as Miloš Obrenović, consolidated autonomy after the Serbian Uprisings of the early 1800s, while Wallachia — united with Moldavia in 1859 to form modern Romania — pursued its own path toward sovereignty under the leadership of Alexandru Ioan Cuza and later Carol I.
Their moment of direct military cooperation came in the Russo-Turkish War of 1877–1878. Serbia, allied with Russia, launched campaigns in the south, while Romania declared war on the Ottoman Empire and committed its army to the siege of Plevna in Bulgaria. Romanian and Serbian troops fought in parallel theatres, their victories contributing to the collapse of Ottoman control in the Balkans. The Treaty of Berlin (1878) formally recognized the full independence of both Romania and Serbia, marking a milestone in their modern histories.
In the early 20th century, the alliance deepened. During World War I, Romania and Serbia both sided with the Entente Powers, each fighting on critical fronts to defend their territory. Serbian forces, after a grueling retreat through Albania, regrouped on the Salonika Front alongside Romanian contingents in other Balkan campaigns.
Following the war, the two states formalized their partnership through the Little Entente (1921), an alliance also including Czechoslovakia. Its aim was to safeguard the post–World War I borders established by the Treaty of Trianon, deter Hungarian revisionism, and maintain mutual defense. Romania and the newly formed Kingdom of Serbs, Croats and Slovenes (later Yugoslavia) used this pact to coordinate military planning, intelligence sharing, and diplomatic positions, ensuring that their political fates remained intertwined even in the modern age.
From medieval battlefields to the diplomatic tables of the 20th century, the Wallachian–Serbian relationship evolved from dynastic alliances to strategic partnerships, yet the underlying theme remained the same: survival and sovereignty through solidarity.
