The Kingdom of Bavaria (German: Königreich Bayern [ˈkøːnɪkʁaɪç ˈbaɪɐn]; Bavarian: Kinereich Bayern [ˈkɪnəraɪ̯x ˈb̥ajɛɐ̯n]; spelled Baiern until 1825) was a German state that succeeded the former Electorate of Bavaria in 1806 and continued to exist until 1918. With the unification of Germany into the German Empire in 1871, the kingdom became a federated state of the new empire and was second in size, power, and wealth only to the leading state, the Kingdom of Prussia.

The polity's foundation dates back to the ascension of Elector Maximilian IV Joseph of the House of Wittelsbach as King of Bavaria in 1806. The crown continued to be held by the Wittelsbachs until the kingdom came to an end in 1918. Most of the border of modern Germany's Free State of Bavaria was established after 1814 with the Treaty of Paris, in which the Kingdom of Bavaria ceded Tyrol and Vorarlberg to the Austrian Empire while receiving Aschaffenburg and Würzburg.

Franconia (German: Franken [ˈfʁaŋkn̩] ; East Franconian: Franggn [ˈfrɑŋɡŋ̍]; Bavarian: Frankn) is a geographical region of Germany, characterised by its culture and East Franconian dialect (Ostfränkisch). Franconia is made up of the three Regierungsbezirke (governmental districts) of Lower, Middle and Upper Franconia in Bavaria, the adjacent, Franconian-speaking South Thuringia, south of the Thuringian Forest—which constitutes the language boundary between Franconian and Thuringian—and the eastern parts of Heilbronn-Franconia in Baden-Württemberg.

Those parts of the Vogtland lying in Saxony (largest city: Plauen) are sometimes regarded as Franconian as well, because the Vogtlandian dialects are mostly East Franconian. The inhabitants of Saxon Vogtland, however, mostly do not consider themselves Franconian. On the other hand, the inhabitants of the Hessian-speaking parts of Lower Franconia west of the Spessart (largest city: Aschaffenburg) do consider themselves Franconian, although not speaking the dialect. Heilbronn-Franconia's largest city of Heilbronn and its surrounding areas are South Franconian-speaking, and therefore only sometimes regarded as Franconian. In Hesse, the east of the Fulda District is Franconian-speaking, and parts of the Oden Forest District are sometimes regarded as Franconian for historical reasons, but a Franconian identity did not develop there.

Aschaffenburg (Low Franconian: Aschebersch) is a Landkreis (district) in Bavaria, Germany. It is bounded by (from the west and clockwise) the districts of Darmstadt-Dieburg, Offenbach, Main-Kinzig (all in the state of Hesse), the districts Main-Spessart and Miltenberg, and the City of Aschaffenburg.
