Born in Darmstadt, Hessen, Germany in 1669, George Louis of Hesse-Darmstadt was the third son of Louis VI, Landgrave of Hesse-Darmstadt. After the early death of his father, he was raised by his mother Elisabeth Dorothea of Sachsen-Gotha. In 1686 he undertook a "Grand Tour" through France and Switzerland. As youngest son, he had little chance of becoming Landgrave, and therefore he was destined for a military career.
Military career
First he fought against the Turks under Prince Eugene of Savoy. He was present at the Battle of Mohacs. Then he joined William III of Orange in the Irish campaign. After his return he converted to Catholicism and became Generalfeldwachtmeister in the Austrian Army in 1692, at the age of 23. Then he fought against the French in the Nine Years' War. In 1695 he was sent by the Emperor to Spain at the head of an army-unit of 2,000 German soldiers to help defend Catalonia against superior French army and navy forces. In 1697 he defended Barcelona which was under siege by Vendôme by land and admiral D’Estrées by sea. Finally the city surrendered after a siege of 52 days. This was ordered from Madrid and against the will of prince George Louis.
Later life
After the war he was honoured in Spain and made a knight in 1697 of the Order of the Golden Fleece. After the withdrawal of the French, he became Viceroy of Catalonia, being recorded in the Spanish official records as Jorge de Darmstadt. He learned some Catalan and initiated some reforms, making him quite popular in the region. In 1699 he was appointed General der Kavallerie. But in 1700 King Carlos II died and was succeeded as king by the French Philip V. Prince George Louis was replaced in 1701 by a pro-Bourbon Viceroy: Luis Antonio Tomás Fernández de Portocarrero, and he returned to Austria. There, he was ordered by the Emperor Leopold to negotiate an alliance with England and Portugal to support the claims to the Spanish throne of Leopold's son, the Archduke Charles. After the start of the War of the Spanish Succession he was appointed the head of the Austrian troops supporting Archduke Charles's cause in Spain. In January 1704, Admiral Sir George Rooke with Prince George on board sailed from Lisbon for Barcelona, hoping it would declare for Archduke Charles. This proved false and the fleet returned to Lisbon after a brush with French naval forces heading to Toulon. On 31 July upon the suggestion of Prince George and under his command, 1,800 Dutch and English Marines were landed near Gibraltar, took the fortress along with Sir George Rooke, Admiral of the Fleet and defended it successfully against a Spanish-French siege, holding off repeated attacks. Following the arrival of Allied reinforcements and supplies, enabling Prince George to take the offensive, the siege was abandoned in April 1705. He left Gibraltar and took command of the conquest of Barcelona and was killed on 13 September, storming the citadel of Montjuich. His body was embalmed and buried in the Església dels Josepets de Gràcia. His heart was sent in 1711 to Darmstadt, where it remains in the Stadtkirche today. He is known by the Catalans as Príncep Jordi. A street in Barcelona was named after him: Carrer del Príncep Jordi.
