I want to know the answer to the following question:
The goal of Metternich and Archduke Charles regarding the Treaty of Schönbrunn was to attempt the preservation of what?
All the background I'm provided with is that "Metternich and Archduke Charles had the preservation of the Habsburg Empire as their fundamental goal, and to this end they succeeded by making Napoleon seek more modest goals in return for promises of friendship between the two powers.". Is that enough to answer the question?
