Information:  - Baden-Württemberg is a state in Germany located in the southwest, east of the Upper Rhine. It is Germanys third largest state in terms of size and population, with an area of and 10.8 million inhabitants. The state capital and largest city is Stuttgart.  - Common Era or Current Era, abbreviated CE, is a calendar era that is used as an alternative naming of the "Anno Domini" era ("in the year of the Lord"), abbreviated AD.  The system uses BCE as an abbreviation for "before the Common (or Current) Era" and CE as an abbreviation for "Common Era". The CE/BCE designation uses the same numeric values as the "Anno Domini" year-numbering system first used by the 6th-century Christian monk Dionysius Exiguus. Neither notation includes a year zero, and the two notations (CE/BCE and AD/BC) are numerically equivalent; thus " CE" corresponds to "AD ", and "400 BCE" corresponds to "400 BC". The Gregorian calendar and the year-numbering system associated with it is the calendar system with most widespread use in the world today. For decades, it has been the global standard, recognized by international institutions such as the United Nations and the Universal Postal Union.  - The Julian calendar, proposed by Julius Caesar in 46 BC (708 AUC), was a reform of the Roman calendar. It took effect on 1 January 45 BC (AUC 709) (shortly before the Roman conquest of Egypt), by edict. It was the predominant calendar in the Roman world, most of Europe, and in European settlements in the Americas and elsewhere, until it was refined and gradually replaced by the Gregorian calendar, promulgated in 1582 by Pope Gregory XIII. The Julian calendar gains against the mean tropical year at the rate of one day in 128 years. For the Gregorian the figure is one day in 3,030 years. The difference in the average length of the year between Julian (365.25 days) and Gregorian (365.2425 days) is 0.002%.  - Otto of Sankt Blasien was a German Benedictine chronicler . He was born about the middle of the 12th century ; died on 23 July 1223 , at Sankt Blasien in the Black Forest , Baden ( southwestern Germany ) . Nothing is known of the events of his life . It is probable that in his later days he became abbot of the renowned Benedictine monastery of Sankt Blasien . He is known as the writer who continued the chronicles of Otto of Freising , like whom he possessed a great talent for presenting a clear survey of events . His language was lofty , and followed the model of the ancient classics . Like many of his contemporaries , he liked to apply the fixed formulas of Justinian to the German emperors , probably on the assumption , then widespread , that the Holy Roman Empire was only the continuation of the Roman Empire of the Caesars . His chronicles , written in the form of annals , `` Ad librum VII chronici Ottonis Frisingensis episcopi continuatae historiae appendix sive Continuatio Sanblasiana '' , embrace the period from 1146 to 1209 , that is the period from Conrad III to the murder of Philip of Swabia . Since he was distant in time from the facts he narrates , his accounts are quite objective , even though he makes no concealment of his prejudice in favour of the Hohenstaufen dynasty , which in 1218 received the bailiwick of St. Blasien from the dukes of Zahringen . Yet , after Otto of Brunswick was recognized as Holy Roman emperor , he writes of him in the same objective way as of his predecessors . Nevertheless , without any apparent cause , the narrative breaks off at the coronation of Otto IV. Perhaps the chronicler shrank from describing the bloody party conflicts of the times . His chief sources were the `` Gesta Friderici '' and perhaps Alsatian chronicles . On the whole his statements may be trusted . It is only when he has to resort to oral reports that he becomes unreliable ; this is especially the case in his chronology , though he is not to be reproached with intentional misrepresentation of facts...  - As a means of recording the passage of time, the 12th century is the period from 1101 to 1200 in accordance with the Julian calendar in the Common Era. In the history of European culture, this period is considered part of the High Middle Ages and is sometimes called the Age of the Cistercians.

The dynasty ruled much of the Middle East during the 12th and 13th centuries CE. Saladin had been the vizier of Fatimid Egypt before toppling the Fatimids in 1171. Three years later, he proclaimed himself sultan following the death of his former master, the Zengid ruler Nur al-Din. For the next decade, the Ayyubids launched conquests throughout the region and by 1183, they controlled Egypt, Syria, northern Mesopotamia, Hejaz, Yemen, and the North African coast up to the borders of modern-day Tunisia. Most of the Kingdom of Jerusalem fell to Saladin after his victory at the Battle of Hattin in 1187. However, the Crusaders regained control of Palestine's coastline in the 1190s.  - The High Middle Ages or High Medieval Period was the period of European history around the 11th, 12th, and 13th centuries (c. 10011300). The High Middle Ages were preceded by the Early Middle Ages and followed by the Late Middle Ages, which by convention end around 1500.  - Year 1200 (MCC) was a leap year starting on Saturday (link will display the full calendar) of the Julian calendar.  - 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 .  - Year 1101 (MCI) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar.
