The outbreak of the First World War marked a dramatic turning point for the House of Saxe-Coburg and Gotha, a dynasty whose fortunes had, for decades, been intricately woven into the fabric of European royalty. Their network, once a symbol of stability and cosmopolitan ambition, became a source of vulnerability as the continent descended into an era defined by rising nationalism and suspicion of foreign entanglements. The pan-European marriages that had long bound the Coburgs to the thrones of Britain, Belgium, Bulgaria, and Portugal now placed them at the epicenter of public skepticism and political turmoil. Contemporary diplomatic dispatches and government memos reveal that the house, which had once championed supranational unity, found itself fragmented by the very borders and allegiances that war had redrawn.
In Britain, the dynasty’s German roots became a target for vitriol as the horrors of the Western Front unfolded. Newspapers and satirical cartoons of the period frequently invoked the royal family’s Germanic surname as a symbol of perceived duplicity. Cabinet minutes and private correspondence among ministers document acute anxiety that royal ties to Germany would undermine the monarchy’s legitimacy at home. By 1917, these pressures reached a crescendo. Historical records indicate that King George V, mindful of both public sentiment and the monarchy’s precarious standing, issued a royal proclamation renouncing the name Saxe-Coburg and Gotha in favor of Windsor. This change, deeply symbolic, was not merely cosmetic; it was a deliberate act to sever the visible links to Germany and align the royal house with British national identity. Court documents confirm that the renaming extended to all descendants and branches residing in Britain. Even the names of royal residences and military regiments were scrutinized and Anglicized, as the monarchy sought to erase the traces of its Germanic heritage from official memory.
Material culture from the period underscores this transformation. Inventories of royal regalia, uniforms, and even official stationary were altered to reflect the new house name. Ceremonial occasions at Buckingham Palace and Windsor Castle, once characterized by continental flourishes, adopted a more distinctly British character—a shift observable in both dress and protocol, as contemporary photographs and descriptions attest. The monarchy’s public rituals, designed to project unity and continuity, became tools for reinforcing a new, insular identity.
Beyond Britain, the war’s consequences rippled through other Coburg-ruled realms. In Bulgaria, Tsar Ferdinand I—whose accession was itself a product of Coburg diplomacy—was compelled to abdicate in 1918 in the wake of military defeat and revolutionary agitation. Archival materials from Sofia depict a court beset by crisis, as Ferdinand’s son, Boris III, inherited a throne deeply destabilized by economic collapse, occupation, and the rise of radical ideologies. Bulgarian state papers from the era report frequent cabinet reshuffles, political assassinations, and protests that challenged both the monarchy’s authority and the legitimacy of the Coburg line.
In Belgium, King Albert I, grandson of Leopold I, faced a different ordeal. Contemporary Belgian sources celebrate Albert’s leadership and personal courage during the German invasion, and his decision to remain with his troops became a symbol of national resilience. Yet, behind the mythos, government reports and diaries reveal the profound trauma of occupation, the devastation of industry and infrastructure, and the enduring scars on the national psyche. The Coburgs’ presence, while a rallying point, was also a reminder of the era’s contradictions: a family of German origin presiding over a nation brutalized by German forces.
Elsewhere, the Coburgs’ influence was in retreat. In Portugal, the dynasty’s fortunes had already waned following the assassination of King Carlos I in 1908 and the republican revolution of 1910. Portuguese government decrees and exile memoirs document the abrupt end of monarchy and the dispersal of royal assets, as the last Coburg king, Manuel II, lived out his days abroad, stripped of crown and country. Central Europe, too, saw the erosion of Coburg authority as the postwar settlement dismantled empires, redrew borders, and rendered noble titles increasingly obsolete.
Material evidence of this decline is preserved in the fate of the family’s architectural and artistic patrimony. Inventories and estate records from Coburg and Gotha chronicle the transformation of grand palaces into museums, administrative offices, or boarding schools. The sale of art collections, silver, and jewels—often documented in auction house ledgers—reflects the dynasty’s struggle to meet the costs of modernity and political change. Formerly bustling halls fell silent, their ceremonial pomp replaced by the rhythms of public tours or bureaucratic routine. Contemporary travelers’ accounts sometimes describe the faded grandeur of ballrooms now stripped of their splendor, the once-crowded stables emptied of horses.
Internally, the house’s cohesion frayed under the pressures of war and exile. Family correspondence from the interwar years, preserved in various archives, illuminates disputes over property, titles, and the question of national allegiance. Some members, particularly those remaining in Britain or Belgium, adapted to their new national identities, embracing the ceremonial and charitable roles that survived the loss of political power. Others, especially those in exile or reduced circumstances, clung to memories of a vanished pan-European dynasty, fostering nostalgia and, at times, bitterness. The regular family congresses and reunions that had once symbolized Coburg unity became rare, replaced by private visits and discreet exchanges of letters.
The Second World War further complicated the house’s legacy. Records from this period reveal a spectrum of responses: some descendants faced accusations of collaboration or complicity with fascist regimes, while others actively participated in resistance movements or endured persecution and exile. Postwar scholarship, drawing on court documents, intelligence files, and personal accounts, continues to debate the extent of Coburg involvement on different sides of the conflict, highlighting the complexity and ambiguity of their position.
By the mid-twentieth century, the House of Saxe-Coburg and Gotha was a shadow of its former self. Its palaces were quieter, its dynastic web reduced to scattered threads, and its identity fractured by the traumas of war, revolution, and adaptation. Yet, even as its influence waned, the house endured in diminished form—a testament to both the resilience and the vulnerability of Europe’s royal families in an age of unprecedented upheaval. The legacy of the Coburgs, preserved in archives, museums, and contested memories, remained open to reassessment as Europe itself continued to change.
