A member of the Teschen branch of the House of Habsburg-Lorraine and an Archduchess of Austria and Princess of Bohemia, Hungary, and Tuscany by birth, she renounced her titles in 1909 upon her marriage to Prince Jerome Radziwiłł.

Renata’s father was a grandson of Archduke Charles of Austria who had led the Austrian army against Napoleon Bonaparte.

[1] Archduke Charles Stephen put aside his career in the navy and centered his ambitions in creating a Polish branch of the House of Habsburg.

He encouraged all of his children to become Polish and Archduchess Renata ended up marrying one of Poland's richest landowners, Prince Jerome Radziwill.

Towards the end of World War II, Prince Jerome was captured by Soviet troops and he was taken behind the Iron Curtain.
