Casimir I of Kuyavian (in Polish Kazimierz I Kujawski), the dynasty Piasts, was born around 1211 and died on 14 December 1267. It is the second son of Conrad I of Mazovia and Agafia, the daughter of Prince Sviatoslav of Vladimir-Volhynia.

It was Duke of Kuyavian (from 1233), Duke of Lad (in Greater Poland) from 1239 to 1261, Duke of Wyszogród (from 1242), Duke of Sieradz from 1247 to 1261, Duke of Łęczyca (at from 1247) and Duke of Dobrzyń (from 1248).

Duke of Kujavia

He obtained the duchy of Kuyavian in 1233, the lifetime of his father. On the occasion of his marriage to Constance in 1239, he received as dowry Lad. In the years following the marriage, it seeks to support the policy of his father who seeks the throne of Krakow. To thank him, his father offered him Wyszogród in 1242.

[Edit] A fratricidal

His father Conrad died on 31 August 1247. In his will he provides the duchies of Sieradz and Łęczyca to his youngest son Siemovit, his eldest son Boleslaw receiving Mazovia. This will does not Casimir who declared war on his two brothers. He drives his brother Siemowit of Sieradz and Łęczyca.

The situation geopolitics in the region change suddenly in the spring of 1248, following the sudden death of Boleslaw I of Mazovia. This leaves all his possessions to his younger brother Siemovit. Taking advantage of the confusion following the death of Boleslaw, Casimir takes the place still-strong Dobrzyń nad Wisła.

[Edit] Map of peace and opposition to Teutoniques

Starting from 1250, Casimir is trying to establish peaceful relations with Sudoviens which regularly ravaged its territory. Unfortunately the peace plan will be thwarted by Teutoniques invited in the region by his father in 1226. Yet, his initiative like the pope and, in 1254, the legate Papal throw the anathema on Teutoniques trying to sabotage the peace talks with the Sudoviens. Finally, these negotiations will not succeed, Casimir being called on other border areas. In order to secure the northern border of its territory, it uses the Templars who settled in Łuków. It was not until 1263 that it normalizes its relations with the Teutons.

[Edit] The war (1258-1261)

Meanwhile, a storm hit the Kuyavian. In 1258, the Duke of Greater Poland Boleslaw the Pious, allied to the Duke of Warcisław Vorpommern, launched an offensive against Casimir, claiming the restitution of Lad, which has been illegally given by Henry II the Pious. This attack fails Boleslaw the Pious but not giving up. The following year, he succeeded in bringing great dukes in its coalition against Kuyavian (the Duke of Krakow Boleslaw V the modest, Siemovit I of Mazovia and Daniel de Galicia). Casimir is obliged to request the cessation of hostilities on 29 November 1259 against the promise made to the Great Lad Poland. The peace negotiations are difficult and require the coalition to launch a new attack against Kuyavian in 1261. Taking advantage of the weakening of his father and the confusing political situation, Lech II the Black, the eldest son of Casimir, he claims his inheritance. Finally, in 1261, Casimir Lad not only lost but also the Duchy of Sieradz it between his son.

[Edit] Marriages and descendants

Casimir was married three times. His first wife was called Hedwige and was probably the daughter of Ladislas Odonic. That first marriage did not give him offspring. His second wife named Constance, the daughter of Henry II the Pious. From this marriage were born two boys (Lech II Black and Siemomysl of Inowrocław) and daughter (Adelaide). His third wife was called Euphrosyne of Opole. She had three son (Ladislas the Short I, II Casimir Łęczyca and Siemovit of Dobrzyń) and a girl (understatement).

Casimir I of Kuyavian died on 14 December 1267. He was buried in the cathedral of Włocławek.
