The life of Infante Alfonso, Duke of Galliera, was defined by his pioneering role as a military aviator and his complex political position within the Spanish monarchy. Born in Madrid in 1886, he navigated the turbulent transition between the reign of his cousin King Alfonso XIII and the eventual establishment of the Second Spanish Republic.
Early Life and Education
Alfonso María Francisco Antonio Diego was the son of Infante Antonio, Duke of Galliera, and Infanta Eulalia of Spain. In 1899, he relocated to England to attend Beaumont College, where he remained until 1904. He later continued his studies at Heidelberg University. In 1906, he graduated from the Academia Militar de Toledo to begin his formal military service.

After completing pilot training in France in 1910, Alfonso established himself as a central figure in early Spanish aviation. His technical leadership was notably applied during the 1925 amphibious landings at Al Hoceima in Morocco. By February 1931, he held the rank of Chief of Staff of the Spanish Air Force and Commander of the First Aero District. Throughout his career, he balanced his duties as a military officer with significant diplomatic travel, including a 1930 expedition on the Graf Zeppelin that took him from Seville to Brazil and New York City.
Political Exile and Military Service
The advent of the Second Spanish Republic in 1931 resulted in Alfonso's exile to London. Following his return to Spain in 1932, he was detained at Villa Cisneros. On 1 January 1933, he participated in an escape with approximately thirty other monarchist prisoners, crossing 1800 miles to reach Lisbon. During the Spanish Civil War, he returned to Spain to command aerial forces under General Francisco Franco, eventually earning the rank of brigadier general by 1943. He resigned from the Air Force in 1945 to express support for the Count of Barcelona and the restoration of the monarchy.
Marriage and Personal History
In 1909, Alfonso married Princess Beatrice of Saxe-Coburg and Gotha. The union took place via three separate ceremonies in Coburg. Because the marriage occurred without the official consent of King Alfonso XIII, he was briefly stripped of his Spanish titles and honours. However, these were restored in 1912 by royal decree. Alfonso and Beatrice had three children: Alvaro, Alfonso, and Ataúlfo. He passed away in 1975 at his residence in Sanlúcar de Barrameda.
