Eisenach in the context of "Gotha"

Erfurt (German pronunciation: [ˈɛʁfʊʁt] ) is the capital and largest city of the Central German state of Thuringia, with a population of around 216,000. It lies in the wide valley of the River Gera, in the southern part of the Thuringian Basin, north of the Thuringian Forest, and in the middle of a line of the six largest Thuringian cities (Thüringer Städtekette), stretching from Eisenach in the west, via Gotha, Erfurt, Weimar and Jena, to Gera in the east. Together with Kassel and Göttingen, it is one of the cities with more than 100,000 inhabitants lying closest to the geographic centre of Germany. Erfurt is 100 km (62 mi) south-west of Leipzig, 250 km (155 mi) north-east of Frankfurt, 300 km (186 mi) south-west of Berlin and 400 km (249 mi) north of Munich.

Erfurt's old town is one of the best preserved medieval city centres in Germany. The Gera is spanned by the Merchants' Bridge (Krämerbrücke), one of the rare bridges with houses built on it. On the Erfurt Cathedral Hill is the ensemble of Erfurt Cathedral—which houses the world's largest free-swinging medieval bell—and St Severus' Church. Petersberg Citadel is one of the largest and best preserved town fortresses in Central Europe. Erfurt's Old Synagogue is the oldest synagogue in Europe, and together with the Erfurt Mikveh [de], which was only rediscovered in 2007, and the Stone House [de], forms the UNESCO World Heritage Site Jewish-Medieval Heritage of Erfurt.

Johann Sebastian Bach (31 March [O.S. 21 March] 1685 – 28 July 1750) was a German composer and musician of the late Baroque period. He is known for his prolific output across a variety of instruments and forms, including the orchestral Brandenburg Concertos; solo instrumental works such as the cello suites and sonatas and partitas for solo violin; keyboard works such as the Goldberg Variations and The Well-Tempered Clavier; organ works such as the Schübler Chorales and the Toccata and Fugue in D minor; and choral works such as the St Matthew Passion and the Mass in B minor. Since the 19th-century Bach Revival, he has been widely regarded as one of the greatest composers in the history of Western music.

The Bach family had already produced several composers when Johann Sebastian was born as the last child of a city musician, Johann Ambrosius, in Eisenach. After being orphaned at age 10, he lived for five years with his eldest brother, Johann Christoph, then continued his musical education in Lüneburg. In 1703 he returned to Thuringia, working as a musician for Protestant churches in Arnstadt and Mühlhausen. Around that time he also visited for longer periods the courts in Weimar, where he expanded his organ repertory, and the reformed court at Köthen, where he was mostly engaged with chamber music. By 1723 he was hired as Thomaskantor (cantor with related duties at St Thomas School) in Leipzig. There he composed music for the principal Lutheran churches of the city and Leipzig University's student ensemble, Collegium Musicum. In 1726 he began publishing his organ and other keyboard music. In Leipzig, as had happened during some of his earlier positions, he had difficult relations with his employer. This situation was somewhat remedied when his sovereign, Augustus III of Poland, granted him the title of court composer of the Elector of Saxony in 1736. In the last decades of his life, Bach reworked and extended many of his earlier compositions. He died due to complications following eye surgery in 1750 at the age of 65. Four of his twenty children, Wilhelm Friedemann, Carl Philipp Emanuel, Johann Christoph Friedrich, and Johann Christian, became composers.

Gera (German pronunciation: [ˈɡeːʁa] ) is a city in the German state of Thuringia. With around 93,000 inhabitants, it is the third-largest city in Thuringia after Erfurt and Jena as well as the easternmost city of the Thüringer Städtekette, an almost straight string of cities consisting of the six largest Thuringian cities from Eisenach in the west, via Gotha, Erfurt, Weimar and Jena to Gera in the east. Gera is the largest city in the Vogtland, and one of its historical capitals along with Plauen, Greiz and Weida. The city lies in the East Thuringian Hill Country, in the wide valley of the White Elster, between Greiz (upstream) and Leipzig (downstream). Gera is located in the Central German Metropolitan Region, approximately 60 kilometres (37 miles) south of Saxony's largest city of Leipzig, 80 km (50 miles) east of Thuringia's capital Erfurt, 120 km (75 miles) west of Saxony's capital Dresden and 90 km (56 miles) north of Bavaria's city of Hof (Saale).

First mentioned in 995 and developing into a city during the 13th century, Gera has historical significance as being one of the main residences of the Ducal House of Reuss and subsequently the capital of the Principality of Reuss-Gera (1848-1918) and of the People's State of Reuss (1918-1920), one of the many microstates the Thuringian region consisted of, before they were unified to form Thuringia in 1920.

The Thuringian Forest (Thüringer Wald in German pronounced [ˈtyːʁɪŋɐ ˈvalt] ) is a mountain range in the southern parts of the German state of Thuringia, running northwest to southeast. Skirting from its southerly source in foothills to a gorge on its north-west side is the Werra valley. On the other side of the Forest is an upper outcrop of the North German Plain, the Thuringian Basin, which includes the city of Erfurt. The south and south-east continuation of the range is the highland often called the Thuringian-Vogtlandian Slate Mountains.

Among scattered foothills at its northern foot are the towns Eisenach, Gotha and Arnstadt. The towns of Ilmenau and Suhl sit in slight dips on the range itself to the north and south respectively.

The Social Democratic Workers' Party of Germany (German: Sozialdemokratische Arbeiterpartei Deutschlands, SDAP) was a Marxist socialist political party in the North German Confederation during unification.

Founded in Eisenach in 1869, the SDAP endured through the early years of the German Empire. Often termed the Eisenachers, the SDAP was one of the first political organizations established among the nascent German labor unions of the 19th century. It officially existed under the name SDAP for only six years (1869–1875). However, through name changes and political partnerships, its lineage can be traced to the present-day Social Democratic Party of Germany (SPD).

Saxe-Eisenach (German: Sachsen-Eisenach) was an Ernestine duchy ruled by the Saxon House of Wettin. The state intermittently existed at three different times in the Thuringian region of the Holy Roman Empire. The chief town and capital of all three duchies was Eisenach.
