Austro-Hungarian Navy
The Austro-Hungarian Navy or Imperial and Royal War Navy was the naval force of Austria-Hungary. Ships of the Austro-Hungarian Navy were designated SMS, for Seiner Majestät Schiff. The k.u.k. Kriegsmarine came into being after the formation of Austria-Hungary in 1867, and ceased to exist in 1918 upon the Empire's defeat and subsequent collapse at the end of World War I.
Before 1867, the Imperial Austrian Navy or simply the Austrian Navy, saw action in the French Revolutionary Wars, the Napoleonic Wars, the Austrian expedition against Morocco, the Second Egyptian–Ottoman War, the First and Second Wars of Italian Independence, the Second Schleswig War, and the Third War of Italian Independence. Following Austria's defeat by Prussia and Italy during the Seven Weeks' War, the Austrian Empire reformed itself into the dual monarchy of Austria-Hungary, and the navy also became the Austro-Hungarian Navy. Largely neglected by the Empire in its early years, the k.u.k. Kriegsmarine expanded along with Austro-Hungarian industrialization into one of the largest navies in the Adriatic and Mediterranean Seas. By 1914, the k.u.k. Kriegsmarine had a peacetime strength of 20,000 personnel, seeing action in the Boxer Rebellion and other conflicts before World War I.
During most of World War I, the Allied Powers maintained the Otranto Barrage to bottle up the k.u.k. Kriegsmarine in the Adriatic Sea. Largely tasked with defending the Empire's of coastline and of island seaboard, the Navy chose to rely on its U-boats to attack Allied shipping rather than risk the destruction of its battleships, cruisers and other surface vessels. In June 1918, it attempted to break the Otranto Barrage with a large naval fleet, but the attack was called off after the battleship was sunk by an Italian torpedo boat on 10 June.
Five months later, with the Austro-Hungarian Empire facing collapse and defeat in the war, the Empire decided to transfer most of its navy to the newly declared State of Slovenes, Croats and Serbs on 31 October, effectively bringing the k.u.k. Kriegsmarine to an end. Three days later, the Empire's military authorities signed the Armistice of Villa Giusti, pulling the rapidly disintegrating empire out of the war. With the signing of the Treaty of Saint-Germain-en-Laye and the Treaty of Trianon, Austria and Hungary became landlocked, and the Empire's most important ports of Trieste, Pola, Fiume and Ragusa became part of Italy and Yugoslavia. The k.u.k. Kriegsmarine's main ships were turned over to the Allies, who scrapped most of them in the 1920s during the era of naval disarmament.
History
Origins
The k.u.k. Kriegsmarine was not formally established until the 18th century, but its origins can be traced back to 1382, with the incorporation of Trieste into the Duchy of Austria. During the 13th and 14th centuries, Trieste became a maritime trade rival to the Republic of Venice, which occupied the Adriatic port city for intermittent periods between 1283 and 1372. Under the terms of the Peace of Turin in 1381, Venice renounced its claim to Trieste and the leading citizens of Trieste petitioned Leopold III, Duke of Austria, to make the port part of his domains. The agreement incorporating Trieste into the Duchy of Austria was signed at the castle of Graz on 30 September 1382.While Austria had a port with the incorporation of Trieste, the city was granted a large degree of autonomy and successive Dukes of Austria paid little attention to the port or the idea of deploying a navy to protect it. Until the end of the 18th century, there were only limited attempts to establish an Austrian navy. During the Thirty Years War, Generalissimo Albrecht von Wallenstein was awarded the Duchies of Mecklenburg-Schwerin and Mecklenburg-Güstrow as well as given the title "Admiral of the North and Baltic Seas" by Holy Roman Emperor Ferdinand II in 1628 after scoring several military victories against Denmark–Norway in northern Germany. However, Wallenstein failed to capture Stralsund, which resisted the Capitulation of Franzburg and the subsequent siege with assistance of Danish, Scottish and Swedish troops, a blow that denied him access to the Baltic and the chance of challenging the naval power of the Scandinavian kingdoms and of the Netherlands. Wallenstein's assassination at the hands of his own officers in 1634 prevented the development of any Austrian navy in either the North or Baltic Seas.
The next incursion Austria took into naval affairs occurred on the Danube River rather than at sea. During the Great Turkish War, Prince Eugene of Savoy employed a small flotilla of ships along the Danube to fight the Ottoman Empire, a practice which the House of Habsburg had employed previously during the 16th and 17th centuries to fight during Austria's numerous wars with the Ottomans. These river flotillas were largely manned by crews who came from Austria's coastal ports, and played a significant role in transporting troops across the Danube as well as denying Turkish control over the strategically important river. Significant portion of the Danube flotila were made up by Serb Šajkaši.
Austria remained without a proper seagoing navy, however, even after the need for one became apparent with the French Navy bombardment of the port of Trieste during the War of Spanish Succession. Lacking any sea power, Austria was unable to protect its coastal cities or project power into the Adriatic or Mediterranean Seas. The war ended with the treaties of Utrecht, Rastatt, and Baden. Under the terms of the Treaty of Rastatt, Austria gained the Spanish Netherlands, the Kingdom of Naples, the Kingdom of Sicily, the Kingdom of Sardinia, and the Duchy of Milan. While Austria's control over Sardinia and Naples was cut short by their loss to Spain in 1734 during the War of Polish Succession, these territories as well as the new Austrian Netherlands gave Austria greater access to the sea than ever before.
Following the War of Spanish Succession, Austria once again developed interest in establishing a proper navy in order to protect its now numerous coastal possessions. This coincided with the majority of European nations' growing interest in mercantilism, the founding and development of colonies, and the chartering of overseas trading companies during the early 18th century. Austria's largest obstacle in engaging in overseas trade and naval enterprises however lay in the country's geography. Despite Austria having a lengthy coastline along the Adriatic Sea, the major ports it possessed along its main coastline were isolated from Vienna by the large Austrian Alps. Furthermore, there were no major rivers linking Austria's Adriatic ports to the interior of the country. Austria also enjoyed three major navigable rivers which flowed through the country, the Elbe, the Oder, and the Danube. However, the Elbe and the Oder flowed through the Kingdom of Prussia before emptying into the North and Baltic Sea respectively, while the mouth of the Danube lay within the territory of the Ottoman Empire. Both of these nations remained major rivals of Austria throughout the 18th century, preventing the Austrians from using its major rivers to gain access to the sea.
The Ostend Company
Following the War of Spanish Succession, Austria's greatest outlet to the sea lay in the newly acquired Austrian Netherlands. While non-contiguous with the rest of Austria, the Austrian Netherlands lay within the boundaries of the Habsburg-dominated Holy Roman Empire. The territory also possessed numerous ports with easy access to the Atlantic Ocean, such as Ghent, Antwerp, Bruges and Ostend. However, the economy of the Austrian Netherlands was very disconnected from the rest of Austria, and most Habsburg rulers paid little attention to the province. Even Prince Eugene of Savoy, upon being appointed Governor-General of the Austrian Netherlands in June 1716, chose to remain in Vienna and direct policy through his chosen representative, Hercule-Louis Turinetti, marquis of Prié.The success of the Dutch, British and French East India Companies throughout the 17th and early 18th centuries however led the merchants and shipowners of Ostend to want to establish direct commercial relations with the East Indies. In December 1722, Charles VI granted a 30-year charter to the Ostend Company to conduct trade with the East and West Indies, as well as Africa. The Ostend Company proved to be immensely profitable, and between 1724 and 1732, 21 company vessels were sent out to conduct trade in the Caribbean, Africa, and especially Asia. The most profitable voyages of the Ostend Company were to Canton, as rising tea prices resulted in high profits for ships conducting trade with China. Between 1719 and 1728, the Ostend Company transported 7 million pounds of tea from China, roughly half of the total amount brought to western Europe at the time, placing the company on par in the tea trade with the East India Company. The Ostend Company proved to be short lived however, as Charles VI suspended the charter of the company due to British diplomatic requests following the Treaty of Vienna, with the company ceasing operations in 1731.
Charles VI and Maria Theresa
Believing that "Navigation and commerce are the foremost pillars of the state," Holy Roman Emperor Charles VI engaged in other projects beyond the establishment of the Ostend Company in order to increase Austria's merchant marine and establish a proper navy to protect it. This included constructing a new road through the Semmering Pass in order to link Vienna to Trieste, and declaring Trieste and Fiume free ports in 1719. In order to help protect Austrian merchants from piracy in the Adriatic and Mediterranean, Charles VI purchased the 80-gun ship of the line Cumberland from Britain in 1720. The ship was renamed San Carlos and stationed out of Naples before being decommissioned and broken up in 1733.On the Adriatic, Charles VI constructed even more ships, usually employing Italian and Spanish officers to man them. This Adriatic fleet consisted of three ships of the line, one frigate, and several galleys. In total, this Adriatic fleet had 500 guns and a crew of 8,000 men. Following the end of the Ostend Company however, a committee was set up in 1738 by the Emperor to examine the status of Austria's Adriatic fleet. Its report concluded that the fleet "had little usefulness, caused great expense, and stood in danger of being defeated in case of attack". This report eventually led to Charles VI scrapping his Adriatic fleet and transferring most of officers and crew members to Austria's Danube Flotilla.
Upon the death of Charles VI on 19 October 1740, Saxony, Prussia, Bavaria, and France all repudiated the Pragmatic Sanction of 1713 which had paved the way for Charles' daughter Maria Theresa to succeed him. Frederick II of Prussia almost immediately invaded Austria in December 1740 and took the affluent Habsburg province of Silesia in the seven-year conflict known as the War of the Austrian Succession. This conflict proved to be primarily a land-based war for Austria, which led to naval affairs being neglected by the newly crowned Maria Theresa, who spent the entirety of the war preoccupied with securing her inheritance of the throne of Austria as opposed to rebuilding her father's former fleet in the Adriatic.
By the time the Seven Years' War began in 1756, Austria still lacked a proper navy. Enemy pirates and privateers, as well as Barbary corsairs severely hampered Austria's merchant marine, to the point that most of Austria's sea trade had to be conducted in foreign ships. The lack of any naval force to protect Austria's shipping led Count Kaunitz to push for the creation of a small force of frigates to protect the Adriatic Sea. However, the Seven Years' War forced Vienna to pay much more attention to Austria's land border with Prussia and its coastline along the Adriatic Sea, preventing Kaunitz's program from achieving success.
In 1775, another attempt to formulate an overseas trading company was undertaken with the establishment of the Austrian East India Company. Headed by William Bolts, the company's first voyage to India began on 24 September 1776 with Bolts sailing aboard the Indiaman Giuseppe e Teresa from Livorno in the Grand Duchy of Tuscany, which was ruled by Maria Theresa's son Leopold. Bolts was also granted a 10-year charter to trade under the flag of the Holy Roman Empire with Persia, India, China and Africa.
The Austrian East India Company marked the first attempt by Austria to establish overseas colonies. Within the next two years, Bolts established factories on the Malabar Coast, on the southeastern African coast at Delagoa Bay, and at the Nicobar Islands. These ventures ultimately failed however due to pressure from other colonial powers such as Portugal and Denmark-Norway, both of which forcefully evicted Bolts and his colonists from Africa and the Bay of Bengal respectively. Furthermore, the Austrian government did not wish to provoke other foreign powers after having to fight two major continental wars in the span of just 20 years. Vienna was also unwilling to lend much monetary support to either the company or towards the creation of a navy sufficiently large enough to protect its interests. This was partially because the Austrian government expected the ports of Trieste and Fiume to bear the cost of constructing and maintaining a fleet.
