Subsequently, Habsburg dynasty bore the title until the fall of the Empire and the liquidation of the Duchy of Cieszyn in 1918.

On 23 April 1618 Elizabeth Lucretia was married against her will with the also ex-Lutheran Gundakar of Liechtenstein, a widower almost twenty years her senior.

[1][2] Gundakar was a younger brother of Karl I, Duke of Opava (Troppau) and Krnov (Jägerndorf), one of the members of the Regency council who ruled the Duchy of Cieszyn during Frederick William's absence; however, this arrangement was short-lived, and the de facto rule was held by Elizabeth Lucretia, even after Frederick William returned to Cieszyn and assumed the effective government in 1624, because the Duke almost immediately after his return made a trip with the Emperor to the Dutch Republic.

During this journey, Frederick William became suddenly ill and died on 19 August 1625 in Cologne, unmarried and without legitimate issue.

Elizabeth Lucretia's life was seriously threatened on several occasions: for example, in 1642, when she had to find refuge in Jablunkov and in 1645, when she escaped to Kęty, after the Swedish forces took the capital (which capitulated only in 1646).
