Dusseldorf (UK: /'[email protected]:rf/ [email protected], US: /'dju:s-/ DEWS-, German: ['dYsldoRf] (listen); often Dusseldorf in English sources; Low Franconian and Ripuarian:[a] Dusseldorp ['[email protected](@)p];[tone?] Archaic Dutch: Dusseldorp ('[email protected](@.p)) is the capital of North Rhine-Westphalia. It is also the largest state in Germany. With a population of 617.280, it is the second-largest municipality in the state, and seventh in Germany. 
Dusseldorf lies at the confluence two rivers, the Rhine and the Dussel. A small tributary is also found there. The suffix -dorf means \"village\" (English cognate is thorp). It's unusual to use it for a large settlement like Dusseldorf. The majority of the city is located on the right bank, unlike Cologne which lies on the river's left side. Dusseldorf is located in the middle of the Rhine-Ruhr Metropolitan Region and the Rhineland Metropolitan Region. It borders the Cologne Bonn Region in the south and Ruhr in the north. It is the largest German Low Franconian language area city (closely related with the Dutch).
According to Mercer's 2012 Quality of Living Survey, Dusseldorf was ranked sixth in terms of livability.  Dusseldorf Airport, Germany's third busiest airport, is the main international hub for residents of the Ruhr, Germany’s largest urban area. Dusseldorf is a major international financial and business centre. It is well-known for its fashion and trade shows. Messe Dusseldorf hosts nearly a fifth of the world's premier trade shows.  Dusseldorf is the second-largest Rhineland city and hosts Rhenish Carnival celebrations every February/March. These celebrations are the third most popular in Germany, after those in Mainz and Cologne.
