Wieluń Land in the context of "Częstochowa"

The last will and testament of the Piast duke Bolesław III Wrymouth of Poland, established rules for governance of the Polish kingdom by his four surviving sons after his death. By issuing it, Bolesław planned to guarantee that his heirs would not fight among themselves, and would preserve the unity of his lands under the Piast dynasty. However, soon after his death his sons fought each other, and Poland entered a period of fragmentation lasting about 200 years.

Wieluń [ˈvjɛluɲ] (Latin: Velun) is a town in south-central Poland with 21,624 inhabitants (2021). The town is the seat of the Gmina Wieluń and Wieluń County, and is located within the Łódź Voivodeship. Wieluń is a capital of the historical Wieluń Land.

Wieluń has a long and rich history. In the past, it used to be an important urban trade centre of the Kingdom of Poland. Several Polish kings and notables visited the town, but following the catastrophic Swedish Deluge (1655–1660), Wieluń declined and never regained its status. In September 1939, during the invasion of Poland, it was heavily bombed by the Luftwaffe. The Bombing of Wieluń is considered to be the first World War II bombing in Europe. It killed at least 127 civilians, injured hundreds more and destroyed the majority of the town.
