Władysław's rule as Duke of Kraków and High Duke of Poland lasted for four years, until 1206, when, after the death of his principal supporter voivode Mikołaj Gryfita, Leszek I the White returned to the capital. The cause of the rebellion was a tough enforcement of rights against the powerful nobility and the alliance with the Pomeranians. Some historians placed the loss of Kraków by Władysław in an earlier period: a few months after the death of his father in 1202. In the absence of sources for this period, however, this fact is difficult to verify.
