Question: Who were the neighbors of the Salian Franks who lived in the 4th largest city in Germany?
Context: Cologne ( ; German: "Köln" , ] , Colognian: "Kölle" ] ) is the largest city in the German federal State of North Rhine-Westphalia and the fourth-largest city in Germany (after Berlin, Hamburg, and Munich).  It is located within the Rhine-Ruhr metropolitan region, one of the major European metropolitan areas, and with more than ten million inhabitants, the largest in Germany.  Cologne is about 45 km southwest of North Rhine-Westphalia's capital of Dusseldorf and 25 km northwest of Bonn.    is a city and municipality in Rogaland county, Norway.  It is the 8th largest city in Norway and it lies immediately south of the city of Stavanger, the 4th largest city in Norway.  Together, the Stavanger/Sandnes area is the 3rd largest urban area in Norway. The Salian Franks, also called the Salians (Latin: "Salii", Greek: "Salioi"), were a northwestern subgroup of the early Franks who first appear in the historical records in the third century.  They are contrasted with their neighbours to the east, the Ripuarian Franks, whose capital was in Cologne. Merovech (415-458) is the semi-legendary founder of the Merovingian dynasty of the Salian Franks (although either Childeric I, his supposed son, or Clovis I, his supposed grandson, may in fact be the founder), which later became the dominant Frankish tribe.  He is said to be one of several barbarian warlords and kings that joined forces with the Roman general Aetius against the Huns under Attila on the Catalaunian fields in Gaul.  The first Frankish royal dynasty called themselves Merovingians ("descendants of Meroveus") after him, although no other historical evidence exists that Merovech ever lived. Shahran is one of the largest tribes in the 'Asir region of Saudi Arabia.  Shahrani lands are bordered by Subay' and Al-Shalaowah (الشلاوة وسبيع ) from the north, 'Abida and Rofaidah from the east (عبيدة ورفيدة ), Al Njou’ from the South (النجوع ), and Banou Sha’ba, Mogaidah, Banou Melk, Bal’smar, Banou Sheher, Balgern and Shamran from the west.  (بنو شعبة ومغيدة وبنو مالك وبلحمر وبلسمر وبنو شهر وبلقرن وشمران ).  The noticed density to the west of Shahrani lands is due to the presence of the large city of Abha (آبها ) in that direction.  Through history, tribal wars have been waged between the two neighbors, especially between Shahran and the other major tribe of the area, Qahtan (قحطان ).  Such wars are, of course, no longer waged after the formation of the Kingdom of Saudi Arabia.  Shahran’s largest and main city is Khamis Mushayt (The largest city in ‘Asir, and the 8th largest in Saudi Arabia with an estimated population of 630,000).  Khamis Mushayt is noted for being the fourth largest trading center in Saudi Arabia, and is famous for its world-class military airbase. Chlodio (c. 392/395–445/448; also spelled Clodio, Clodius, Clodion, Cloio or Chlogio) was a king of the Salian Franks from the Merovingian dynasty.  He was known as the Long-Haired King and lived in Thuringian territory, at the castle of Duisburg.  He became chief of the Thérouanne area in 414 AD.  From there, he invaded the Roman Empire in 428, defeating a Roman force at Cambrai, and settled in Northern Gaul, where other groups of Salians were already settled.  Although he was attacked by the Romans, he was able to maintain his position and, 3 years later in 431, he extended his kingdom south to the Somme River in the future Francia.  In AD 448, 20 years after his reign began, Chlodio was defeated at Vicus Helena in Artois by Flavius Aëtius, the commander of the Roman army in Gaul. The Merovingians ( ) were a Salian Frankish dynasty that ruled the Franks for nearly 300 years in a region known as Francia in Latin, beginning in the middle of the 5th century.  Their territory largely corresponded to ancient Gaul as well as the Roman provinces of Raetia, Germania Superior and the southern part of Germania.  Childeric I (c. 457 – 481), the son of Merovech, leader of the Salian Franks, founded the Merovingian dynasty, but it was his famous son Clovis I (481–511) who united all of Gaul under Merovingian rule. Waterbury (nicknamed "The Brass City") ( ) is a city in the U.S. state of Connecticut on the Naugatuck River, 33 miles (45 minutes) southwest of Hartford and 77 miles (90 minutes) northeast of New York City.  Waterbury is in New Haven County, Connecticut.  As of the 2010 census, Waterbury had a population of 110,366, making it the 10th largest city in the New York Metropolitan Area, 9th largest city in New England and the 5th largest city in Connecticut. Renton is a city in King County, Washington, United States.  Situated 11 mi southeast of downtown Seattle, Washington, Renton straddles the southeast shore of Lake Washington, at the mouth of the Cedar River.  While long an important salmon fishing area for Native Americans, Renton was first settled by people of European descent in the 1860s, and its early economy was based on coal mining, clay production, and timber export.  Today, Renton is best known as the final assembly point for the Boeing 737 family of commercial airplanes, but it is also home to a growing number of well known manufacturing, technology, and healthcare organizations, including Boeing Commercial Airplanes Division, Paccar, Kaiser Permanente, IKEA, Providence Health & Services, UW Medicine Valley Medical Center, and Wizards of the Coast.  As of 2016, the population in Renton is 101,300, up from 90,927 at the 2010 census.  Renton currently is the 8th largest city in Washington State, and is the 4th largest in King County.  The National Football League's Seattle Seahawks have a training facility in Renton.  It is the second-largest facility in the NFL at 200000 sqft . While German-speaking people have a long history, Germany as a nation state dates only from 1871.  Earlier periods are subject to definition debates.  The Franks, for instance, were a union of Germanic tribes; nevertheless, some of the Franks later identified themselves as Dutch, Flemish, French and again others as Germans.  The capital of medieval ruler Charlemagne's empire was the city of Aachen, now part of Germany, yet he was a Frank.  France was named after the Franks and the Dutch and Flemish people are the only ones to speak a language that descends from Frankish (the language of the Franks).  Hence nearly all continental Western European historians can claim his victories as their heritage.  The Holy Roman Empire he founded was largely but far from entirely German speaking.  The Kingdom of Prussia, which unified Germany in the 19th century, had significant territory in what is now Poland.  In the early 19th century, the philosopher Schlegel referred to Germany as a "Kulturnation", a nation of shared culture and political disunity, analogous to ancient Greece.  Until the unification of 1871, Austria was considered a part of Germany even though much of its empire was not in the Holy Roman Empire and was non-German.
