Regensburg in the context of "Limes Germanicus"

Saint Emmeram's Abbey (German: Kloster Sankt Emmeram or Reichsabtei Sankt Emmeram) was a Benedictine monastery founded around 739 at Regensburg in Bavaria (modern-day southeastern Germany) at the grave of the itinerant Frankish bishop Saint Emmeram. The original abbey church is now a parish church named St. Emmeram's Basilica. The other buildings on the site form a large complex known as Schloss Thurn und Taxis or Schloss St. Emmeram, which has served as the main residence of the Thurn und Taxis princely family since the early 19th century.

Saint Emmeram of Regensburg (also Emeram(m)us, Emmeran, Emmerano, Emeran, Heimrammi, Haimeran, or Heimeran) was a Christian bishop and a martyr born in Poitiers, Aquitaine. Having heard of idolatry in Bavaria, Emmeram travelled to Ratisbon (Regensburg) some time after the year 649 to the court of Theodo I, Duke of Bavaria. He supposedly travelled up the Loire, crossed through the Black Forest and then followed the Danube to Regensburg. Theodo welcomed Emmeram to his court, where he laboured for three years carrying out missionary work. During this time, he gained a reputation as a pious man. He died circa 652 and is buried in St. Emmeram's in Regensburg, Germany. His feast day in the Catholic Calendar of saints is September 22.

The War of the Fifth Coalition was a European conflict in 1809 that was part of the Napoleonic Wars and the Coalition Wars. The main conflict took place in Central Europe between the Austrian Empire of Francis I and Napoleon's French Empire. The French were supported by their client states—the Kingdom of Italy, the Confederation of the Rhine and the Duchy of Warsaw. Austria was supported by the Fifth Coalition which included the United Kingdom, Portugal, Spain, and the Kingdoms of Sardinia and Sicily, although the latter two took no part in the fighting. By the start of 1809 much of the French army was committed to the Peninsular War against Britain, Spain and Portugal. After France withdrew 108,000 soldiers from Germany, Austria attacked France to seek the recovery of territories lost in the 1803–1806 War of the Third Coalition. The Austrians hoped Prussia would support them, having recently been defeated by France, but Prussia chose to remain neutral.

On 10 April 1809, Austrian forces under Archduke Charles crossed the border of Bavaria, a French client state. The French response, under Louis-Alexandre Berthier, was disorganised but order was imposed with the arrival of Napoleon on 17 April. Napoleon led an advance to Landshut, hoping to cut off the Austrian line of retreat and sweep into their rear. Charles crossed the Danube at Regensburg, which allowed him to retreat eastwards, although he failed to reach the Austrian capital, Vienna, before the French. A French assault across the Danube was repulsed on 21–22 May at the Battle of Aspern-Essling but a repeat attack was successful in July. Napoleon won a major victory at the 5–6 July Battle of Wagram, which forced the Austrians to sign the Armistice of Znaim on 12 July. Austrian invasions of the Duchy of Warsaw and Saxony (where they fought alongside the Black Brunswickers) were repulsed and they were driven out of their territories in Italy. British forces landed in Walcheren, in the French client state of Holland, but were unable to seize their objective of capturing Antwerp and later withdrew.

The Diocese of Regensburg (Latin: Dioecesis Ratisbonensis; German: Bistum Regensburg) is a Latin Church diocese of the Catholic Church with its episcopal see based in Regensburg, Germany. Its district covers parts of northeastern Bavaria; it is subordinate to the archbishop of Munich and Freising. As of 2014, the diocese had 1.20 million Catholics, constituting 70% of its total population. The current bishop is Rudolf Voderholzer. The main diocesan church is Saint Peter in Regensburg. The diocese is divided into eight regions and 33 deaneries with 769 parishes. It covers an area of 14,665 km.

Central or Middle Bavarian form a subgroup of Bavarian dialects in large parts of Austria and the Free State of Bavaria along the Danube river, on the northern side of the Eastern Alps. They are spoken in the 'Old Bavarian' regions of Upper Bavaria (with Munich), Lower Bavaria and in the adjacent parts of the Upper Palatinate region around Regensburg, in Upper and Lower Austria, in Vienna (see Viennese German), in the state of Salzburg, as well as in the northern and eastern parts of Styria and Burgenland. Before 1945 and the expulsions of the Germans, it was also spoken in Hungary and southern Bohemia and Moravia.It also influenced Austrian German.

The Agilolfings were a noble family that ruled the Duchy of Bavaria on behalf of their Merovingian suzerains from about 550 until 788. A cadet branch of the Agilolfings also ruled the Kingdom of the Lombards intermittently from 616 to 712.They are mentioned as the leading dynasty in the Lex Baiuvariorum (c. 743). Their Bavarian residence was at Regensburg.

The dynasty's eponymous ancestor is Agilulf, a semi-legendary prince of the Suebi and descendant of Hermeric, the 5th-century Suevic king of Galicia, possibly identical with one Agilulf, a steward of the Visigothic king Theoderic II, who was executed in 457.

The Perpetual Diet of Regensburg or the Eternal Diet of Regensburg, (German: Immerwährender Reichstag) also commonly called in English the Perpetual Diet of Ratisbon, from the city's Latin name, was a session of the Imperial Diet (Reichstag) of the Holy Roman Empire that sat continuously from 1663 to 1806 in Regensburg in present-day Bavaria, Germany.

Previously, the Diet had been convened in different cities but, beginning in 1594, it met only in the town hall in Regensburg. On 20 January 1663, the Diet convened to deal with threats from the Ottoman Empire (the Turkish Question). Since the Peace of Westphalia in 1648, the Holy Roman Emperor had been formally bound to accept all decisions made by the Diet. Hence, out of fear that the Emperor would disregard the Diet's role by not calling sessions, it never dissolved and became a perpetual diet. Therefore, no final report of its decisions, known as a Recess, could be issued, and that of the preceding diet, issued in 1654, was dubbed the Youngest Recess [de]. From 1663 until the 1684 Truce of Ratisbon (a former name of Regensburg in English), the diet gradually developed into a permanent body.

The Imperial Diet (German: Reichstag; Latin: Dieta Imperii or Comitium Imperiale) was the deliberative body of the Holy Roman Empire. It was not a legislative body in the contemporary sense; its members envisioned it more like a central forum where it was more important to negotiate than to decide.

Its members were the Imperial Estates, divided into three colleges. The diet as a permanent, regularized institution evolved from the Hoftage (court assemblies) of the Middle Ages. From 1663 until the end of the empire in 1806, it was in permanent session at Regensburg.
