Viola and her children moved to Kalisz, where they remained after Henry I's death in 1238, while his son and successor, Henry II the Pious, took over the regency of Opole-Racibórz. Soon after, Mieszko II began to claim rule over his duchy. Henry II was forced to accept this, and by late 1238 or early 1239, Mieszko II returned to Opole and began his independent rule. Viola and her second son Władysław were expected to remain in Kalisz, which was held under the guidance of Henry II. Viola remained as regent of the Duchies of Kalisz and Wieluń on behalf of Władysław until 1241, when he was declared an adult and able to rule in his own right.
