How did Archbishop Adalbert of Bremen gain influence over Henry IV?

Archbishop Adalbert of Bremen gained influence over Henry IV by positioning himself as a more permissive alternative to the rigid and dominating rule of Anno, archbishop of Cologne.1

Following the kidnapping of the young king in 1062, Anno had taken control of the government, but his inflexible nature failed to win the boy's confidence. Adalbert successfully courted Henry's favor by granting the young king more personal freedom and indulging his interests. By serving as a guardian and tutor, Adalbert secured significant political ascendancy and was granted extensive powers in Saxony in 1063. However, Adalbert ultimately used this position for unscrupulous personal enrichment, which led to his dismissal as a royal adviser in 1066 following intense pressure from the nobility.12
