How a German prince became the king who unified modern Romania against his kin
In short: Ferdinand I was born into the Prussian Hohenzollern dynasty, yet he led Romania into World War I against Germany. This choice cost him his place in his own family register but earned him the title of the Unifier, as his reign saw the birth of a vastly expanded Greater Romania.
Born in 1865 in southwestern Germany, Ferdinand was a member of the Hohenzollern-Sigmaringen branch. He became the heir to the Romanian throne in 1886 after his father and older brother renounced their claims. Upon succeeding his uncle, King Carol I, in 1914, Ferdinand faced the immense pressure of a continent at war. Despite his German heritage, he swore to govern as a true Romanian, a promise that eventually led him to join the Triple Entente in 1916. This decision prompted Kaiser Wilhelm II to strike his name from the royal house records.
The war years were perilous. After the Central Powers occupied Wallachia and Dobruja, Romania was forced into a difficult position following Russia's 1918 exit from the conflict. Ferdinand famously refused to ratify the resulting Treaty of Bucharest. When Allied forces shifted the momentum, he re-mobilized his army, ultimately securing the incorporation of territories like Transylvania, Bukovina, and Bessarabia. In 1922, he was formally inaugurated as the monarch of this enlarged state during an elaborate event held at the Coronation Cathedral in Alba Iulia.
Ferdinand's personal life was marked by complex dynastic and social pressures. His 1893 marriage to Princess Marie of Edinburgh was reportedly unhappy, and his later years were clouded by a succession crisis. In 1925, his eldest son, Prince Carol, abandoned his rights to the throne, leading Ferdinand to remove him from the royal house. When Ferdinand died from cancer in 1927 at age 61, the crown passed to his young grandson, Michael, under a three-person regency. His legacy remains defined by the radical transformation of Romanian society, including significant agrarian reforms and the introduction of universal suffrage.
