In 1259, Adolf succeeded his father as Count of Berg.
King Rudolph I of Germany allowed Adolf to move his mint to Wipperfürth in 1275. In 1276 Adolf granted city rights to Ratingen and in 1282 to Wipperfürth. Adolf tried unsuccessfully to assert his claim and in 1283 he sold his right to Duke John I of Brabant.
The counter-claims of Duke John and Reginald I ultimately led to the Battle of Worringen in 1288 in which Adolf supported the victorious Brabant. Archbishop Siegfried was captured and imprisoned by Adolf in Schloss Burg for 13 months. As a result of the victory, Adolf was also able to elevate Düsseldorf to the level of city.
Through trickery, Archbishop Siegfried was able to capture Adolf in 1292 and held him in prison until he died on 28 September 1296. As Adolf and Elisabeth had no issue, Adolf's brother William I of Berg succeeded him as Count of Berg.
