The German Navy is part of the unified Bundeswehr, the German Armed Forces. The German Navy was originally known as the Bundesmarine from 1956 to 1995, when Deutsche Marine became the official name with respect to the 1990 incorporation of the East German Volksmarine. It is deeply integrated into the NATO alliance. Its primary mission is protection of Germany's territorial waters and maritime infrastructure as well as sea lines of communication. Apart from this, the German Navy participates in peacekeeping operations, and renders humanitarian assistance and disaster relief. It also participates in anti-piracy operations.
The Imperial German Navy or the Kaiserliche Marine was the navy of the German Empire, which existed between 1871 and 1919. It grew out of the small Prussian Navy, which was mainly for coast defence. Kaiser Wilhelm II greatly expanded the navy. The key leader was Admiral Alfred von Tirpitz, who greatly expanded the size and quality of the navy, while adopting the sea power theories of American strategist Alfred Thayer Mahan. The result was a naval arms race with Britain, as the German navy grew to become one of the greatest maritime forces in the world, second only to the Royal Navy.
Alfred Peter Friedrich von Tirpitz was a German grand admiral and State Secretary of the German Imperial Naval Office, the powerful administrative branch of the German Imperial Navy from 1897 until 1916.
Ludwig von Henk was a German naval officer, who distinguished himself in the Prussian Navy and later in the Imperial German Navy of the German Empire. He retired as a Vice-Admiral.
The Prussian Navy, officially the Royal Prussian Navy, was the naval force of the Kingdom of Prussia from 1701 to 1867.
The Imperial Russian Navy operated as the navy of the Russian Tsardom and later the Russian Empire from 1696 to 1917. Formally established in 1696, it lasted until dissolved in the wake of the February Revolution of 1917. It developed from a smaller force that had existed prior to Tsar Peter the Great's founding of the modern Russian navy during the Second Azov campaign in 1696. It expanded in the second half of the 18th century and reached its peak strength by the early part of the 19th century, behind only the British and French fleets in terms of size.
The term Reichskriegsflagge refers to several war flags and war ensigns used by the German armed forces in history. A total of eight different designs were used in 1848–1849 and between 1867–1871 and 1945.
Eduard Karl Emanuel von Jachmann was the first Vizeadmiral of the Prussian Navy. He entered the navy in the 1840s after initially serving in the merchant marine. In 1848, Jachmann received his first command, the corvette SMS Amazone; through the 1850s and early 1860s, he held several other commands, including the frigates Thetis—aboard which he took part in the Eulenburg expedition to East Asia—and Arcona. During the Second Schleswig War in 1864, he commanded Prussian naval forces in the Baltic from Arcona, and led a small squadron at the Battle of Jasmund on 17 March. Though defeated in that battle, he was promoted to Konteradmiral for his aggressive handling of the Prussian fleet.
SMS Prinz Adalbert was an ironclad warship of the Prussian Navy and later the Imperial fleet. She was built in Bordeaux, France in 1864 for the Confederate States Navy. Prussia bought her during the Second Schleswig War against Denmark, but she was not delivered until after the war. She was designed as an armored ram but also carried three guns: one 21 cm (8.3 in) and two 17 cm (6.7 in) pieces in armored turrets. She was named after Prince Adalbert of Prussia, an early proponent of Prussian naval power.
Kaiserliche Werft Wilhelmshaven was a German shipbuilding company in Wilhelmshaven, founded in 1871 and closed in 1918. Together with Kaiserliche Werft Danzig and Kaiserliche Werft Kiel it was one of three shipyards which solely produced warships for the Preußische Marine and the following German Kaiserliche Marine. With the end of World War I all three imperial shipyards were closed, but the Wilhelmshaven shipyard was reopened in 1919, first as Reichsmarinewerft Wilhelmshaven, and after 1935 named Kriegsmarinewerft Wilhelmshaven.
The Imperial German Army (1871–1919), officially referred to as the German Army, was the unified ground and air force of the German Empire. It was established in 1871 with the political unification of Germany under the leadership of Prussia, and was dissolved in 1919, after the defeat of the German Empire in World War I (1914–1918). In the Federal Republic of Germany, the term Deutsches Heer refers to the German Army, the land component of the Bundeswehr.
Seebataillon, literally "sea battalion", is a German term for certain troops of naval infantry or marines. It was used by the Prussian Navy, the North German Federal Navy, the Imperial German Navy, the Austro-Hungarian Navy, the Kriegsmarine, and briefly in the Bundesmarine. In 2014, also the modern German Navy established a naval force protection unit called Seebataillon.
The Navy League or Fleet Association in Imperial Germany was an interest group formed on April 30, 1898 on initiative of Admiral Alfred von Tirpitz through the German Imperial Naval Office (Reichsmarineamt) which he headed (1897–1916) to support the expansion of the Imperial German Navy (Kaiserliche Marine). Specifically it was intended to develop popular pressure on the German parliament (Reichstag) to approve the Fleet Acts of 1898 and 1900, and the attendant expenses.
The Reichsflotte was the first navy for all of Germany, established by the revolutionary German Empire to provide a naval force in the First Schleswig War against Denmark. The decision was made on 14 June 1848 by the Frankfurt Parliament, which is considered by the modern German Navy as its birthday.
Ernst Otto von Diederichs was a German admiral of the Prussian Navy who served both the Kingdom of Prussia and the German Empire. He was the first governor of the German Jiaozhou Bay concession in China.
The Imperial Naval Office was a government agency of the German Empire. It was established in April 1889, when the German Imperial Admiralty was abolished and its duties divided among three new entities: the Imperial Naval High Command, the Imperial Naval Cabinet and the Imperial Naval Office performing the functions of a ministry for the Imperial German Navy.
The German Imperial Admiralty Staff was one of four command agencies for the administration of the Imperial German Navy from 1899 to 1918. While the German Emperor Wilhelm II as commander-in-chief exercised supreme operational command and control of the naval forces, the military staff was split into the Admiralty, the Naval Office, the Naval Cabinet, and the Inspector-General. The command structure had a negative impact on German naval warfare in World War I, as a professional head of the Imperial Navy, similar to the First Sea Lord, was not established until August 1918. After the war and the German Revolution of 1918–19, the Admiralty Staff became subordinate to the Naval Office and was finally disestablished by order of the German President.
Victor Valois (1841–1924), also called Anton Friedrich Victor Valois, was a vice-admiral (Vizeadmiral) in the German Imperial Navy. He graduated from the post-graduate Naval War College, the Imperial Naval Academy (Marineakademie) in 1874 in a class with three other future admirals: Otto von Diederichs, Felix von Bendemann, Gustav von Senden-Bibran.
Reinhold von Werner was a Prussian and later Imperial German naval officer in the 19th century, eventually reaching the rank of vice admiral. He commanded warships during the three wars of German Unification, the Second Schleswig War, the Austro-Prussian War, and the Franco-Prussian War in 1864, 1866, and 1870–1871, respectively, and during a naval intervention during a revolution in Spain in 1873. His actions off Spain, considered extreme by Chancellor Otto von Bismarck, resulted in his court-martial. He was promoted two years after the intervention in Spain, but was forced into retirement after a major feud with Albrecht von Stosch three years later. Werner wrote numerous books during and after his naval career, and also founded a periodical on maritime topics. He was ennobled in 1901 and died in February 1909.
SMS Basilisk was a Camäleon-class gunboat of the Prussian Navy that was launched in 1862. A small vessel, armed with only three light guns, Basilisk served during all three wars of German unification in the 1860s and early 1870s. The ship was present during the Battle of Heligoland in May 1864 during the Second Schleswig War, but was too slow to engage the Danish squadron. During the Austro-Prussian War of 1866 and the Franco-Prussian War of 1870–1871, Basilisk was stationed in the North Sea to help defend the coast, but she did not see action during either conflict. Between 1873 and 1875, she was employed experimentally as the first torpedo-armed warship of the German fleet. Basilisk was decommissioned in 1875, renamed "Mine Barge No. 1", and converted into a naval mine storage hulk. The details of her fate are unrecorded, but she was still in service in that capacity at least as late as 1900. Sometime thereafter, she was broken up.
