  Medieval Kleve grew together from four parts — the Schwanenburg Castle, the village below the castle, the first city of Kleve on Heideberg Hill, and the "Neustadt" ("New City"), dating from the 14th century. In 1242 Kleve received city rights. The Duchy of Cleves, which roughly covered today's districts of Kleve, Wesel and Duisburg, was united with the Duchy of Mark in 1368, was made a duchy itself in 1417, then united with the neighboring duchies of Jülich and Berg in 1521, when John III, Duke of Cleves, married Mary, heiress of Jülich-Berg-Ravenburg.  Kleve's most famous native is Anne of Cleves (1515–1557), daughter of John III, Duke of Cleves and (briefly) wife of Henry VIII of England. Several local businesses are named after her, including the Anne von Kleve Galerie. The ducal dynasty became extinct in the male line in 1609, leading to a succession crisis in the duchies. After the Thirty Years' War ended in 1648, the succession dispute was resolved with Cleves passing to the elector of Brandenburg, thus becoming an exclave of the Margraviate of Brandenburg, later Brandenburg-Prussia.  The mineral waters of Kleve and the wooded parkland surrounding it made it a fashionable spa in the 19th century. At this time, Kleve was named "Bad Cleve" (English: Spa of Cleves).  Kleve was heavily bombed during the Second World War, and over 90 percent of buildings in the city were severely damaged. Most of the destruction was the result of a raid late in the war in 1945, conducted at the request of Lieutenant-General Brian Horrocks in preparation for Operation Veritable. Horrocks recounted his decision in the 1973 television documentary "The World at War": "Then they came to me and they said, “Do you want the town of Cleves taken out?” By "taken out" they meant the whole of the heavy bombers putting on to Cleves. Now, I knew that Cleves was a very fine old historical German town. Anne of Cleves, one of Henry VIII’s wives, came from there. I knew that there were a lot of civilians in Cleves, men, women and children. If I said no, they would live. If I said yes, they would die. A terrible decision you’ve got to take. But... everything depended on getting a high piece of ground at Materborn. The German reserves would have to come through Cleves, and we would have to breach the Siegfried Line and get there. And your own lives, your own troops, must come first, so I said yes, I did want it taken out. But when all those bombers went over, the night just before zero hour, to take out Cleves, I felt a murderer. And after the war I had an awful lot of nightmares, but always Cleves." Horrocks later said that this had been "the most terrible decision I had ever taken in my life" and that he felt "physically sick" when he saw the bombers overhead.

  As the rest of the Lower Rhine region, Kleve is a predominantly Roman Catholic city. The city is part of the Diocese of Münster. 61.1% of the residents are Roman Catholics, 14.4% Protestant, and 24.6% "Other". The largest section of this group are residents without any religious affiliation, but there are also sizeable Russian Orthodox and Muslim communities in Kleve.  Today, Kleve is governed by a coalition of CDU and the Green Party. Since the last local elections on 25 May 2014 the following parties are represented in Cleves' city council. In addition to nationwide parties, "" (Open Cleves) has a number of seats.

  In 2015, Sonja Northing (no party affiliation) became mayor of Kleve, with 64.5% of the vote. Her candidacy was supported by the SPD and FDP, and opposed by CDU and Green Party candidates. Northing was the first mayor of Cleves since World War I who was not a CDU member.
