Context: In the history of Europe, the Middle Ages or medieval period lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages., The Alemanni (also "Alamanni"; "Suebi" "Swabians") were a confederation of Germanic tribes on the upper Rhine river. First mentioned by Cassius Dio in the context of the campaign of Caracalla of 213, the Alemanni captured the Agri Decumates in 260, and later expanded into present-day Alsace, and northern Switzerland, leading to the establishment of the Old High German language in those regions., The Rhine (, , ) is a European river that begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the 
Swiss-Austrian, Swiss-Liechtenstein, Swiss-German and then the Franco-German border, then flows through the Rhineland and eventually empties into the North Sea in the Netherlands. 
The largest city on the river Rhine is Cologne, Germany, with a population of more than 1,050,000 people. It is the second-longest river in Central and Western Europe (after the Danube), at about , with an average discharge of about ., An archchancellor or chief chancellor was a title given to the highest dignitary of the Holy Roman Empire, and also used occasionally during the Middle Ages to denote an official who supervised the work of chancellors or notaries., The Rhineland is the name used for a loosely defined area of Western Germany along the Rhine River, chiefly its middle section., Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf., Western Germany is a region in the west of Germany. The exact area defined by the term is not constant, but it usually includes North Rhine-Westphalia. The Saarland and Rhineland-Palatinate are also sometimes included but are usually considered Southwestern Germany. Hesse is often considered as Central Germany (together with Thuringia)., Swabia (colloquially "Schwabenland" or "Ländle"; in English also archaic "Suabia" or "Svebia") 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"., The Duchy of Swabia (German: "Herzogtum Schwaben") was one of the five stem duchies of the medieval German kingdom, and its dukes were thus among the most powerful magnates of Germany., The Holy Roman Empire was a multi-ethnic complex of territories in central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806. The largest territory of the empire after 962 was the Kingdom of Germany, though it also came to include the Kingdom of Bohemia, the Kingdom of Burgundy, the Kingdom of Italy, and numerous other territories., Solomon III ( died 919 ) was the Bishop of Constance from 890 to his death . In 885 , the Emperor Charles III made him archchancellor of the Empire , for Konstanz was then the greatest diocese in Swabia , which had been Charles ' original kingdom and was still his home most of the time . As well as bishop , he was also abbot of Reichenau and Saint Gall , immensely powerful abbeys in Swabia and the Rhineland . Solomon founded a church in honour of Saint Magnus at Saint Gall . Solomon was a warlike prelate , originally an ally of both King Louis the Child and Count Palatine Erchanger in the wars for the Swabian dukedom against the Burchards . He was influential in the execution of Burchard I in 911 , but he left his alliance with Erchanger when the latter allied with King Conrad I. Erchanger even imprisoned Solomon in 914 . Conrad , however , supported the bishop and freed him . Conrad later had Erchanger beheaded ., The Suebi (or Suevi, Suavi (Jordanes, Procopius), or Suevians) was a large group of related Germanic peoples who lived in Germania in the time of the Roman Empire. They were first mentioned by Julius Caesar in connection with his battles against Ariovistus in Gaul, around 58 BC. While Caesar treated them as one Germanic tribe within an alliance but the largest and most warlike one, later authors, such as Tacitus, Pliny the Elder and Strabo, specified that the Suevi "do not, like the Chatti or Tencteri, constitute a single nation. They actually occupy more than half of Germania, and are divided into a number of distinct tribes under distinct names, though all generally are called Suebi". At one time, classical ethnography had applied the name "Suevi" to so many Germanic tribes that it appeared as if, in the first centuries AD, that native name would replace the foreign name "Germans"., Subject: solomon iii , Relation: country_of_citizenship, Options: (A) frankfurt (B) gaul (C) germany (D) hamburg (E) holy roman empire (F) italy (G) kingdom of italy (H) liechtenstein (I) netherlands (J) roman empire (K) suebi (L) switzerland
