https://en.wikipedia.org/wiki/Dedi_III,_Margrave_of_Lusatia
Dedi III (German: Dedo), nicknamed the Fat (c.?1130 – 16 August 1190), a member of 
the House of Wettin, was Margrave of Lusatia from 1185 until his death.

Life[edit]

Dedo was a younger son of the Wettin margrave Conrad I of Meissen and his wife 
Luitgard of Ravenstein. From 1144, he administered the lordship of Groitzsch as heir 
apparent of the late Count Henry of Groitzsch (d. 1135), and also as an adopted son 
of his aunt Bertha (d. 1143), Henry's sister and Groitzsch heiress. When Margrave 
Conrad retired in 1156, the extended Wettin estates were divided and Dedi formally 
received the County of Groitzsch and the Lordship of Rochlitz, with jurisdiction over 
the Bishopric of Naumburg.

Dedi participated in five campaigns of the Hohenstaufen emperor Frederick 
Barbarossa to Italy. In 1177, he served as Frederick's envoy to Pope Alexander III and 
swore, on Frederick's behalf, to uphold the Treaty of Venice, which ended the schism 
between pope and emperor.

Back in Germany, Dedi appears to have spent most of his life in Rochlitz. Like his 
elder brother Margrave Otto II of Meissen, he encouraged the settlement of ethnic 
Germans in his territory. He founded Wechselburg Priory as a private monastery, 
where he and his descendants were buried. Together with his elder brothers Margrave 
Otto II of Meissen and Margrave Theodoric I of Lusatia, he was a loyal supporter of 
Emperor Frederick in his conflict with the Welf duke Henry the Lion.

When his brother Theodoric I, who also styled himself a "Margrave of Landsberg", 
died in 1185, Dedi inherited his Lusatian possessions and by appointment of Emperor 
Frederick succeeded him as margrave. In the succession dispute in Meissen upon the 
death of Margrave Otto II in 1190, Dedi and his sons sided with their cousin Albert the 
Proud.

In order to get into shape for participating in the Third Crusade, Dedi had his doctors 
attempt a liposuction. The operation was botched, and as a result, Dedi died on 16 
August 1190.

Marriage and issue[edit]

Dedi married Matilda of Heinsberg and had six children with her:
Dietrich (before 13 September 1159; – 13 June 1207), Count of Sommerschenburg and 
Groitzsch and later provost of Magdeburg
Philip, provost of Xanten (1182-1190)
Conrad II (after 13 September 1159 – 6 May 1210), Margrave of Lusatia
Henry (d. 1174)
Goswin (d. 1174)
Agnes (c.?1160/1165 – 24/26 March 1195)

Dedi was the grandfather of Saint Hedwig of Silesia and great-grandfather of the 
French prince Philip Hurepel. He was also a great-grandfather of Elizabeth of Hungary 
via Gertrude of Merania.
