The Bonn–Oberkassel dog (German: Hund von Bonn–Oberkassel) was a Late Paleolithic (c. 14,000 years BP / c. 12,000 BCE) dog whose skeletal remains were found buried alongside two humans. Discovered in early 1914 by quarry workers in Oberkassel, Bonn, Germany, the double burial site was analyzed by a team of archaeologists from the University of Bonn. It was around 7.5 months old at death, 40–50 cm (16–20 in) tall at the shoulder, and weighed 13–18 kg (29–40 lb), suggesting a slender build similar to West Asian wolves (such as the Indian wolf) or some modern sighthounds. The dog's lower jaw was first thought to be from a wolf and placed into museum storage with the human remains, while the dog's other bones were put into the university's geological collections. The bones of the Bonn–Oberkassel dog were reunited in the late 1970s and reidentified as a domestic dog attributed to the Magdalenian culture, dating to the beginning of the Late Glacial Interstadial, c. 14,000 BP. A total of 32 identifiable bone fragments have been attributed to the dog. These have been used to estimate a number of the animal's characteristics. Osteoarthritis, alongside signs of enamel defects, missing teeth, and gum disease, indicate that the Bonn–Oberkassel dog survived a canine distemper infection as a puppy. Due to the high likelihood of death without assistance, the puppy's survival was probably due to human care. Such care would have involved providing food and water, as well as frequent cleaning. Extensive human care suggests significant compassion towards the dog, possibly indicating that the dog was seen as a pet. It is unknown how the dog died; it may have been due to the effects of its illness or other natural causes. An alternate possibility is that it was killed or sacrificed to be buried alongside the humans, an archaeologically attested practice linked to spiritual and religious motives. A molar belonging to a second, older dog was found at the site, likely used as a grave good.

Construction was completed in 1924–25. The building most recently served as a public library and administration building. As of 2012, the Altes Stadthaus is being renovated and extended as a "House of Learning" (German: "Haus der Bildung"), which will accommodate the community college and the library.

The Max Planck Institute for Mathematics (German: Max-Planck-Institut für Mathematik, MPIM) is a prestigious research institute located in Bonn, Germany. It is named in honor of the German physicist Max Planck and forms part of the Max Planck Society (Max-Planck-Gesellschaft), an association of 84 institutes engaging in fundamental research in the arts and the sciences. The MPIM is the only Max Planck institute specializing in pure mathematics. The Institute was founded by Friedrich Hirzebruch in 1980, having emerged from the collaborative research center "Theoretical Mathematics" (Sonderforschungsbereich "Theoretische Mathematik"). Hirzebruch shaped the institute as its director until his retirement in 1995. Currently, the institute is managed by a board of five directors consisting of Peter Teichner (managing director), Werner Ballmann, Gerd Faltings, Peter Scholze, and Don Zagier. Friedrich Hirzebruch was, and Yuri Manin and Günter Harder are, acting as emeriti.

Bonn Minster (German: Bonner Münster) is a Roman Catholic church in Bonn. It is one of Germany's oldest churches, having been built between the 11th and 13th centuries. At one point the church served as the de facto cathedral for the Archbishopric of Cologne, because it is the major church of what was then the Archbishop-Elector's residence (Cologne itself having secured independence from his secular government). It is now a minor basilica. It served as the inspiration for the Kaiser Wilhelm Memorial Church in Berlin, as Kaiser Wilhelm II had studied in Bonn.

The federal city of Bonn (German pronunciation: [bɔn] (listen) Latin: Bonna) is a city on the banks of the Rhine in the German state of North Rhine-Westphalia, with a population of over 300,000. About 24 km (15 mi) south-southeast of Cologne, Bonn is in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area, with over 11 million inhabitants. It is a university city and the birthplace of Ludwig van Beethoven. It was the capital city of the Electorate of Cologne from 1597 to 1794 and of West Germany from 1949 to 1990. Founded in the 1st century BC as a Roman settlement in the province Germania Inferior, Bonn is one of Germany's oldest cities. From 1597 to 1794, Bonn was the capital of the Electorate of Cologne, and residence of the Archbishops and Prince-electors of Cologne. From 1949 to 1990, Bonn was the capital of West Germany, and Germany's present constitution, the Basic Law, was declared in the city in 1949. The era when Bonn served as the capital of West Germany is referred to by historians as the Bonn Republic. From 1990 to 1999, Bonn served as the seat of government – but no longer capital – of reunited Germany. Due to a political compromise (Berlin-Bonn Act) following the reunification, the German federal government maintains a substantial presence in Bonn. Roughly a third of all ministerial jobs are located in Bonn as of 2019, and the city is considered a second, unofficial, capital of the country. Bonn is the secondary seat of the President, the Chancellor, the Bundesrat and the primary seat of six federal government ministries and twenty federal authorities. The title of Federal City (German: Bundesstadt) reflects its important political status within Germany.The headquarters of Deutsche Post DHL and Deutsche Telekom, both DAX-listed corporations, are in Bonn. The city is home to the University of Bonn and a total of 20 United Nations institutions, the highest number in all of Germany. These institutions include the headquarters for Secretariat of the UN Framework Convention Climate Change (UNFCCC), the Secretariat of the UN Convention to Combat Desertification (UNCCD), and the UN Volunteers programme.

The Cologne War (German: Kölner Krieg, Kölnischer Krieg, Truchsessischer Krieg; 1583–1588) was a conflict between Protestant and Catholic factions that devastated the Electorate of Cologne, a historical ecclesiastical principality of the Holy Roman Empire, within present-day North Rhine-Westphalia, in Germany. The war occurred within the context of the Protestant Reformation in Germany and the subsequent Counter-Reformation, and concurrently with the Dutch Revolt and the French Wars of Religion. Also called the Seneschal's War (Truchsessischer Krieg) or the Seneschal Upheaval (Truchsessischer Wirren) and occasionally the Sewer War, the conflict tested the principle of ecclesiastical reservation, which had been included in the religious Peace of Augsburg (1555). This principle excluded, or "reserved", the ecclesiastical territories of the Holy Roman Empire from the application of cuius regio, eius religio, or "whose rule, his religion", as the primary means of determining the religion of a territory. It stipulated instead that if an ecclesiastical prince converted to Protestantism, he would resign from his position rather than force the conversion of his subjects. In December 1582, Gebhard Truchsess von Waldburg, the Prince-elector of Cologne, converted to Protestantism. The principle of ecclesiastical reservation required his resignation. Instead, he declared religious parity for his subjects and, in 1583, married Agnes von Mansfeld-Eisleben, intending to convert the ecclesiastical principality into a secular, dynastic duchy. A faction in the Cathedral Chapter elected another archbishop, Ernst of Bavaria. Initially, troops of the competing archbishops of Cologne fought over control of sections of the territory. Several of the barons and counts holding territory with feudal obligations to the Elector also held territory in nearby provinces: Westphalia, Liege, and the Southern, or Spanish Netherlands. Complexities of enfeoffment and dynastic appanage magnified a localized feud into one including supporters from the Electorate of the Palatinate and Dutch, Scots, and English mercenaries on the Protestant side, and Bavarian and papal mercenaries on the Catholic side. The conflict coincided with the Dutch Revolt, 1568–1648, encouraging the participation of the rebellious Dutch provinces and the Spanish. In 1586, the conflict expanded further, with the direct involvement of Spanish troops and Italian mercenaries on the Catholic side, and financial and diplomatic support from Henry III of France and Elizabeth I of England on the Protestant side. The war concluded with the victory of the Catholic archbishop Ernst, who expelled the Protestant archbishop Gebhard from the Electorate. This outcome consolidated Wittelsbach authority in north-west Germany and encouraged a Catholic revival in the states along the lower Rhine. More broadly, the conflict set a precedent for foreign intervention in German religious and dynastic matters, which would be widely followed during the Thirty Years' War (1618–1648).
