Swabia

Swabia is a cultural, historic and linguistic region in southwestern Germany. 
The name is ultimately derived from the medieval Duchy of Swabia, one of the German stem duchies, representing the territory of Alemannia, whose inhabitants interchangeably were called "Alemanni" or "Suebi".
This territory would include all of the Alemannic German area, but the modern concept of Swabia is more restricted, due to the collapse of the duchy of Swabia in the thirteenth century. Swabia as understood in modern ethnography roughly coincides with the Swabian Circle of the Holy Roman Empire as it stood during the Early Modern period, now divided between the states of Bavaria and Baden-Württemberg.
Swabians ("Schwaben", singular "Schwabe") are the natives of Swabia and speakers of Swabian German. Their number was estimated at close to 0.8 million by SIL Ethnologue as of 2006, compared to a total population of 7.5 million in the regions of Tübingen, Stuttgart and Bavarian Swabia.
Geography.
Like many cultural regions of Europe, Swabia's borders are not clearly defined. However, today it is normally thought of as comprising the former Swabian Circle, or equivalently the former state of Württemberg (with the Prussian Hohenzollern Province), or the modern districts of Tübingen (excluding the former Baden regions of the Bodenseekreis district), Stuttgart, and the administrative region of Bavarian Swabia.
In the Middle Ages, the term Swabia indicated a larger area, covering all the lands associated with the Frankish stem duchy of Alamannia stretching from the Vosges Mountains in the west to the broad Lech river in the east: This also included the region of Alsace and the later Margraviate of Baden on both sides of the Upper Rhine Valley, as well as modern German-speaking Switzerland, the Austrian state of Vorarlberg and the principality of Liechtenstein in the south.
History.
Early history.
Like all of Southern Germany, what is now Swabia was part of the La Tène culture, and as such has a Celtic (Gaulish) substrate. In the Roman era, it was part of the Raetia province.
The name "Suebia" is derived from that of the "Suebi". 
It is used already by Tacitus in the 1st century, albeit in a different geographical sense:
He calls the Baltic Sea the "Mare Suevicum" ("Suebian Sea") after the Suiones, and ends his description of the Suiones and Sitones with "Here Suebia ends" ("Hic Suebiae finis").
By the mid-3rd century, groups of the Suebi form the core element of the new tribal alliance known as the Alamanni, who expanded towards the Roman Limes east of the Rhine and south of the Main.
The Alamanni were sometimes referred to as Suebi even at this time, and their new area of settlement came to be known as Suebia.
In the migration period, the Suebi (Alamanni) crossed the Rhine in 406 and some of them established the Kingdom of the Suebi in Galicia. Another group settled in parts of Pannonia, after the Huns were defeated in 454 in the Battle of Nedao.
The Alemanni were ruled by independent kings throughout the 4th to 5th century centuries, but fell under Frankish domination in the 6th (Battle of Tolbiac 496).
By the late 5th century, the area settled by the Alemanni extended to the Alsace and the Swiss Plateau, bordering on the Bavarii to the east, the Franks to the north, the remnants of Roman Gaul to the west, and the Lombards and Goths, united in the Kingdom of Odoacer, to the south.
The name "Alamannia" was used by the 8th century, and from the 9th century, "Suebia" was occasionally used for "Alamannia", while "Alamannia" was increasingly used to refer to Alsace specifically. By the 12th century, "Suebia" rather than "Alamannia" was used consistently for the territory of the Duchy of Swabia.
Duchy of Swabia.
Swabia was one of the original stem duchies of East Francia, the later Holy Roman Empire, as it developed in the 9th and 10th centuries. Due to the foundation of the important abbeys of St. Gallen and Reichenau, Swabia became an important center of Old High German literary culture during this period.
In the later Carolingian period, Swabia became once again de facto independent, by the early 10th century mostly ruled by two dynasties, the Hunfriding counts in Raetia Curiensis and the Ahalolfings ruling the Baar estates around the upper Neckar and Danube rivers. 
The conflict between the two dynasties was decided in favour of Hunfriding Burchard II at the Battle of Winterthur (919). Burchard's rule as duke was acknowledged as such by the newly elected king Henry the Fowler, and in the 960s the duchy under Burchard III was incorporated in the Holy Roman Empire under Otto I.
The Hohenstaufen dynasty, which ruled the Holy Roman Empire in the 12th and 13th centuries, arose out of Swabia, but following the execution of Conradin, the last Hohenstaufen, on October 29, 1268, the duchy was not reappointed during the Great Interregnum. In the following years the original duchy gradually broke up into many smaller units.
Rudolf I of Habsburg, elected in 1273 as emperor, tried to restore the duchy, but met the opposition of the higher nobility who aimed to limit the power of the emperor. Instead, he confiscated the former estates of the Hohenstaufen as imperial property of the Holy Roman Empire, and declared most of the cities formerly belonging to Hohenstaufen to be Free Imperial Cities, and the more powerful abbeys within the former duchy to be Imperial Abbeys.
The rural regions were merged into the Imperial Shrievalty ("Reichslandvogtei") of Swabia, which was given as Imperial Pawn to Duke Leopold III of Austria in 1379 and again to Sigismund, Archduke of Austria in 1473/1486. He took the title of a "Prince of Swabia" and integrated the Shrievalty of Swabia in the realm of Further Austria.
Later medieval period.
The Swabian League of Cities was first formed on 20 November 1331, when twenty-two imperial cities of the former Duchy of Swabia banded together in support of the Emperor Louis IV, who in return promised not to mortgage any of them to any imperial vassal. Among the founding cities were Augsburg, Heilbronn, Reutlingen, and Ulm. The counts of Württemberg, Oettingen, and Hohenberg were induced to join in 1340.
The defeat of the city league by Count Eberhard II of Württemberg in 1372
led to the formation of a new league of fourteen Swabian cities on 4 July 1376. 
The emperor refused to recognise the newly revitalised Swabian League, seeing it as a rebellion, and this led to an "imperial war" against the league. The renewed league defeated an imperial army at the Battle of Reutlingen on 14 May 1377.
Burgrave Frederick V of Hohenzollern finally defeated the league in 1388 at Döffingen. The next year the city league disbanded according to the resolutions of the Reichstag at Eger.
The major dynasties that arose out of medieval Swabia were the Habsburgs and the Hohenzollerns, who rose to prominence in Northern Germany. Also stemming from Swabia are the local dynasties of the dukes of Württemberg and the Margraves of Baden. The Welf family went on to rule in Bavaria and Hanover, and are ancestral to the British Royal Family that has ruled since 1714. Smaller feudal dynasties eventually disappeared, however; for example, branches of the Montforts and Hohenems lived until modern times, and the Fürstenberg survive still. The region proved to be one of the most divided in the empire, containing, in addition to these principalities, numerous free cities, ecclesiastical territories, and fiefdoms of lesser counts and knights.
Early modern history.
A new Swabian League ("Schwäbischer Bund") was formed in 1488, opposing the expansionist Bavarian dukes from the House of Wittelsbach and the revolutionary threat from the south in the form of the Swiss.
In 1519, the League conquered Württemberg and sold it to Charles V after its duke Ulrich seized the Free Imperial City of Reutlingen during the interregnum that followed the death of Maximilian I. It helped to suppress the Peasants' Revolt in 1524–26 and defeat an alliance of robber barons in the Franconian War. The Reformation caused the league to be disbanded in 1534.
The territory of Swabia as understood today emerges in the early modern period. It corresponds to the Swabian Circle established in 1512.
The Old Swiss Confederacy was "de facto" independent from Swabia from 1499 as a result of the Swabian War, while the Margraviate of Baden had been detached from Swabia since the twelfth century.
Fearing the power of the greater princes, the cities and smaller secular rulers of Swabia joined to form the Swabian League in the fifteenth century. The League was quite successful, notably expelling the Duke of Württemberg in 1519 and putting in his place a Habsburg governor, but the league broke up a few years later over religious differences inspired by the Reformation, and the Duke of Württemberg was soon restored.
The region was quite divided by the Reformation. While secular princes such as the Duke of Württemberg and the Margrave of Baden-Durlach, as well as most of the Free Cities, became Protestant, the ecclesiastical territories (including the bishoprics of Augsburg, Konstanz and the numerous Imperial abbeys) remained Catholic, as did the territories belonging to the Habsburgs (Further Austria), the Sigmaringen branch of the House of Hohenzollern, and the Margrave of Baden-Baden.
Modern history.
In the wake of the territorial reorganization of the empire of 1803 by the "Reichsdeputationshauptschluss", the shape of Swabia was entirely changed. All the ecclesiastical estates were secularized, and most of the smaller secular states, and almost all of the free cities, were mediatized, leaving only Württemberg, Baden, and Hohenzollern as sovereign states. Much of Eastern Swabia became part of Bavaria, forming what is now the Swabian administrative region of Bavaria.
In contemporary usage, "Schwaben" is often taken to refer to Bavarian Swabia exclusively.
Baden, historically part of the duchy of Swabia but not of the Swabian Circle, is no longer commonly included in the term.
Swabian people.
Language.
SIL Ethnologue cites an estimate of 819,000 Swabian speakers as of 2006. This corresponds to roughly 10% of the total population of the Swabian region, or roughly 1% of the total population of Germany.
As an ethno-linguistic group, Swabians are closely related to other speakers of Alemannic German, i.e. Badeners, Alsatians, and German-speaking Swiss.
Swabian German or German is traditionally spoken in the upper Neckar basin (upstream of Heilbronn), along the upper Danube between Tuttlingen and Donauwörth, and on the left bank of the Lech, in an area centered on the Swabian Alps roughly stretching from Stuttgart to Augsburg.
Many Swabian surnames end with the suffixes "-le", "-(l)er", "-el", "-ehl", and "-lin", typically from the Middle High German diminutive suffix "-elîn" (Modern Standard German "-lein"). Examples would be: "Schäuble", "Egeler", "Rommel", and "Gmelin". The popular German surname "Schwab" as well as "Svevo" in Italy are derived from this area, both meaning literally "Swabian".
