A large part of Silesia was lost in the mid-18th century, but the rest of the Lands passed to the Austrian Empire and the Cisleithanian half of Austria-Hungary.

There were only some common state institutions of the Bohemian Crown that did not survive the centralization of the Habsburg monarchy under Queen Maria Theresa in the 18th century.

The regality was ultimately confirmed by Philip's nephew the German King Frederick II, later the Holy Roman Emperor (1220−1250), in the Golden Bull of Sicily issued in 1212.

His plans to turn Bohemia into the leading Imperial State were aborted by his Habsburg rival King Rudolph I of Germany, who seized his acquisitions and finally defeated him in the 1278 Battle on the Marchfeld.

Together with the Archduchy of Austria "hereditary lands" and the Hungarian kingdom, they formed the Habsburg monarchy, which in the following centuries grew out of the Holy Roman Empire into a separate European power.

Attempts by the Bohemian Protestant Reformation estates to build up an autonomous confederation were dashed at the 1620 Battle of White Mountain, whereafter the administration was centralised at Vienna.
