Prince of Novgorod
After this defeat, Leszek wanted to make an alliance with Mstislav Mstislavich, Prince of Novgorod. This new political approach failed to bring Leszek any positive results, because it prompted an alliance between Daniel Romanovich and Mstislav against him. As a result, the Duke of Kraków lost a small area between the Narew and Bug rivers in 1218.
