In Polish historiography, two contrasting evaluations of Louis's reign in Poland coexisted. The "pessimistic" tradition can be traced back to the views of the late 14th-century Jan of Czarnków, who was banished from Poland during Louis's reign. Czarnków emphasized that "there was no stability in the Kingdom of Poland" and the royal officials "continually pillaged the property of the poor people" during Louis's reign. According to the "optimistic" historiographic tradition, Louis continued Casimir the Great's policy of preserving the unity of Poland against the separatist magnates of Greater Poland with the assistance of lords from Lesser Poland.
