Who married Gertrude of Babenberg, Duchess of Bohemia?

Gertrude of Babenberg (Czech: Gertruda Babenberská; c. 1118 – 8 April 1150), a member of the House of Babenberg, was Duchess consort of Bohemia from 1140 until her death, by her marriage to the Přemyslid duke Vladislaus II.

Vladislaus II or Vladislav II (c. 1110 – 18 January 1174) was the Duke of Bohemia from 1140 and then King of Bohemia (as Vladislaus I) from 1158 until his abdication in 1173. He was the second Bohemian king after Vratislaus II, but in neither case was the royal title hereditary.

Vladislav was the son of Vladislav I and Richeza of Berg. He was married twice, first to Gertrude of Babenberg and then to Judith of Thuringia.
