Richeza and Sverker I had one son, [[Boleslas Sverkerson|Burislav]], who was named after his Polish maternal grandfather.<ref>The chronicles assign [[Sune Sik Sverkersson]] as another son from Richeza and Sverker I, possibly the youngest.

In 11511150, Richeza's oldest son, King Knud V of [[Jutland]], took refuge in Sweden after he was expelled from Denmark by [[Sweyn III of Denmark|Sweyn III Grathe]], King of [[Zealand]]. In this way, the marriage with Sverker I give Richeza the opportunity to help her son, and some historians assume that she partially married with the Swedish King for this reason.<ref name = "Historiska"/> One year later (1151) Knud asked the help of [[Henry the Lion]], Duke of [[Saxony]] and [[Hartwig]], Archbishop of [[Bremen]], but was defeated by Sweyn III's forces. Only after the mediation of the [[German King]] [[Frederick Barbarossa]] during the [[Diet]] in [[Merseburg]] was made a settlement between both parties: Knud V renounced his claim and was compensated by lands in Zealand, while Sweyn III was enfeoffed with the whole Kingdom.<ref name = "DENMARK"<ref>[http://fmg.ac/Projects/MedLands/DENMARK.htm#KnudIIIdied1157 DENMARK]</ref> After this decision, both Knud V and [[Valdemar I of Denmark|Valdemar Knudsson]] (son of Knud Lavard, the enemy of his own father Magnus) rebelled against Sweyn III, who was expelled in 1154: Knud V and Valdemar became co-Kings of Denmark.
In 1156 Knud V married with Princess [[Helena of Sweden]], daughter of King Sverker I and his first wife Ulvhild. In consecuence, Richeza became in the step mother-in-law of her own son. On the [[Christmas Day]] of that year, Sverker I was murdered. One year later, on [[9 August]] [[1157]], King Knud V was also killed during a meeting with Valdemar I and Sweyn III. In 1158 Richeza's second son Niels, probably a monk in Esrom Abbey, also died.<ref name = "DENMARK"/>
Canute married her stepdaughter, the Swedish princess Helena, in 1156. Later the same year, her third husband was killed. Richeza is known to have survived his death, although the date of her death and her later life is unknown: the [[legend]] says that she remarried the stable master who took part in the assassination. ▼
