Kurš apprecējās ar Joan, Countess of Flanders?

Joan, often called Joan of Constantinople (c. 1199 – 5 December 1244), ruled as Countess of Flanders and Hainaut from 1205 (at the age of six) until her death. She was the elder daughter of Baldwin IX, Count of Flanders and Hainaut, and Marie of Champagne.

Orphaned during the Fourth Crusade, Joan was raised in Paris under the tutelage of King Philip II of France. He arranged her marriage to Infante Ferdinand of Portugal in 1212. Ferdinand quickly turned against Philip, starting a war that ended with the defeat of Bouvines and his imprisonment. Joan then ruled her counties alone from the age of 14. She faced the rivalry of her younger sister, Margaret, as well as the revolt of her domains – guided by a man who claimed to be her father. After the end of the war, Ferdinand was released but died soon after. Joan then married Thomas of Savoy. She died in 1244 at the Abbey of Marquette near Lille, having survived her only child, a daughter by Ferdinand.

Joan's policies favored economic development in her counties; in fact, she granted several charters to the Flemish cities. She played an important role in the development of the Mendicant orders, the Beguines, the Victorines and hospital communities in her domains (without neglecting the traditional religious orders). Under her reign, women's foundations increased, transforming the place of women in both society and the church.

The Manessier's Continuation (also called the Third Continuation), one of the novels of the Story of the Grail was written for Joan, as well as the Life of St. Martha of Wauchier de Denain. The first novel in Dutch, Van den vos Reynaerde, was written by a cleric of her court.

There are several painted or sculpted representations of the Countess in France and Belgium, as well as two Géants du Nord.

Thomas II (c. 1199 – 7 February 1259) was the Lord of Piedmont from 1233 to his death, Count of Flanders jure uxoris from 1237 to 1244, and regent of the County of Savoy from 1253 to his death, while his nephew Boniface was fighting abroad. He was the son of Thomas I of Savoy and Margaret of Geneva.

Ferdinand (Portuguese: Fernando, French and Dutch: Ferrand; 24 March 1188 – 27 July 1233) reigned as jure uxoris Count of Flanders and Hainaut from his marriage to Countess Joan, celebrated in Paris in 1212, until his death.
