Anna did not managed to convince her brother Charles IX to participate in her regency, but she cooperated very well with her co-regents, Ernst Philip of Baden and her brothers-in-law Rickard of Simmern and Louis of Württemberg, and successfully managed to solve the problems her regency faced.[1] In 1592, she threatened the Duke of Lorraine with Swedish intervention if he did not stop his son from warring the areas around in Lützelstein.[3] In 1598, Anna successfully made sure that her eldest son Georg Gustav was secured the control of Veldenz, and her younger son Johan August was given full control of Lützelstein, before she retired from power.[3]
