Rainald III. (Burgundy)

from Wikipedia, the free encyclopedia

Rainald III. of Burgundy (around 1093; † 1148 ) was Count of Mâcon and Vienne since 1102 together with his brother Wilhelm III. , and from 1127 Count of Burgundy ( Franche-Comté ). He was a son of Stephan I Tollkopf and Beatrix of Lorraine .

After the death of his cousin Wilhelm III. of the child in 1127 Rainald raised a claim to the county of Burgundy. He got into a war with Duke Konrad I of Zähringen , who also made a claim. The Zähringer had the support of King Lothar III. von Süpplingenburg , who had entrusted him with the rectorate of Burgundy . Rainald was able to assert himself in Besançon , but had to cede all of his areas east of the Jura to the Zähringer.

Around 1130 he married Agathe of Lorraine († in April 1147) daughter of Duke Simon I of Lorraine and Adelheid von Löwen . His only daughter, Beatrix of Burgundy (* probably 1146; † November 15, 1184), was his successor in 1148 and in 1156 the wife of Emperor Friedrich Barbarossa .
