Schleswig-Holstein (German: [ˈʃleːsvɪç ˈhɔlʃtaɪ̯n]) (Danish: Slesvig-Holsten) is the northernmost of the 16 states of Germany, comprising most of the historical duchy of Holstein and the southern part of the former Duchy of Schleswig. Its capital city is Kiel; other notable cities are Lübeck and Flensburg.
The former English name was Sleswick-Holsatia, the Danish name is Slesvig-Holsten, the Low German name is Sleswig-Holsteen, and the North Frisian name is Slaswik-Holstiinj. Historically, the name can also refer to a larger region, containing both present-day Schleswig-Holstein and the former South Jutland County (Northern Schleswig) in Denmark.
The term "Holstein" derives from Old Saxon, Holseta Land, (Holz and Holt mean wood in modern Standardised German and in literary English, respectively). Originally, it referred to the central of the three Saxon tribes north of the River Elbe, Tedmarsgoi, Holstein, and Sturmarii. The area of the Holstein was between the Stör River and Hamburg, and after Christianization, their main church was in Schenefeld. Saxon Holstein became a part of the Holy Roman Empire after Charlemagne's Saxon campaigns in the late eighth century. Since 811, the northern frontier of Holstein (and thus the Empire) was marked by the River Eider.
SMS Schleswig-Holstein (pronounced [ˈʃleːsvɪç ˈhɔlʃtaɪ̯n]) was the last of the five Deutschland-class battleships built by the German Kaiserliche Marine. The ship, named for the province of Schleswig-Holstein, was laid down in the Germaniawerft dockyard in Kiel in August 1905 and commissioned into the fleet nearly three years later. The ships of her class were already outdated by the time they entered service, being inferior in size, armor, firepower and speed to the new generation of dreadnought battleships.
Schleswig-Holstein fought in both World Wars. During World War I, she saw front-line service in the II Battle Squadron of the High Seas Fleet, culminating in the Battle of Jutland on 31 May – 1 June 1916. Schleswig-Holstein saw action during the engagement, and was hit by one large-caliber shell. After the battle, Schleswig-Holstein was relegated to guard duty in the mouth of the Elbe River before being decommissioned in late 1917. As one of the few battleships permitted for Germany by the terms of the Treaty of Versailles, Schleswig-Holstein was again pressed into fleet service in the 1920s. In 1935, the old battleship was converted into a training ship for naval cadets.
Several naval ships of Germany were named Schleswig-Holstein after the federal state of Schleswig-Holstein:
