When his father retired to a monastery in 1238, he ruled the Holstein jointly with his elder brother John I, initially under the guardianship of their brother-in-law the Duke Abel of Schleswig. When they came of age, the brothers took up government and continue their joint rule. In 1255, they concluded a trade agreement with Lübeck.
When their father died in 1261, John and Gerhard divided Holstein. Gerhard took Holstein-Itzehoe, consisting of the districts of Stormarn, Plön and Schaumburg, with his residence in Itzehoe. John received Holstein-Kiel, consisting of the districts Kiel, Wagria and East Holstein, with his seat in Kiel. John later won Rendsburg back from Denmark and traded it with Gerhard for Segeberg.
Gerhard founded several villages, in order to develop Holstein and control the area. He also developed the County's administration. He fought ward with the Archdiocese of Bremen, the City of Lübeck and the landed gentry in his county. In 1262, he won the Battle of the Loh Moor. In 1263, John died and Gerhard became regent of Kiel and Segeberg for John's sons.
The inscription on his seal reads: S(IGILLUM)* GERARDI*COMITIS*HOLTSATIE*ET*DE*SCOWENB(O)RCH ("Seal of Count Gerhard of Holstein and Schauenburg").
