Kurš apprecējās ar Henry VI, Count Palatine of the Rhine?

Henry VI "the Younger" of Brunswick (c. 1196 – 16 or 26 April 1214), of the House of Welf, was Count Palatine of the Rhine from 1212 to 1214.

Henry was born around 1196, the only son of Count Palatine Henry V and Agnes, daughter of Conrad, Count Palatine of the Rhine. In 1212 he was married to Mathilde of Brabant (died 1267), daughter of Henry I, Duke of Lower Lorraine and Brabant.

Henry was raised at the court of his great-uncle, King John of England, and returned to Germany in 1211/1212. On political grounds, Henry's father abdicated the Palatine dignity in his favor in 1212.

At the court assembly in November 1212 in Aachen, Henry took the side of his uncle Otto IV, Holy Roman Emperor. He was presumably engaged to Mathilde of Brabant about the same time. Shortly thereafter he took sides against the party of Otto IV on behalf of Frederick II.

Henry died childless on the 16th or 26 April 1214. He was buried in Schönau Abbey near Heidelberg. He was succeeded as Count Palatine by the Duke Louis I of Bavaria, father of his brother-in-law Otto of Bavaria.

Mathilde of Brabant, also called Machteld (c. 1200 – 22 December 1267), was Countess of Holland by marriage to Floris IV, Count of Holland. She was regent of Holland and Zeeland in 1234–1235.

She was the fourth child and daughter of Mathilde of Flanders and Henry I, Duke of Brabant. She married Henry II, Count Palatine of the Rhine (died 1214) in Aachen in 1212. She married Floris IV, Count of Holland on 6 December 1224.

When her spouse was killed at a tournament at Corbie in 1234, their eldest son William was only seven years old. Mathilde attempted to assume control as regent during his minority, as well as gaining full personal control of the County of Zeeland, which had been promised her as her dowry land. Neither of this was, however, accepted, and in 1235, she was forced to resign for all ambitions of regency. Instead, her sons' paternal uncles William and Otto, bishop of Utrecht, were his guardians until 1239.

After her son attained legal majority Mathilde stepped forward to assume an active role in his court and household, and became a prominent benefactor of abbeys and various institutions.
