Answer: True
Explanation:
At the Congress of Vienna (1814-1815) several territorial agreements were reached. Germany emerged with 39 states, including the two Great Powers, Austria and Prussia, some minor kingdoms, smaller duchies, tiny principalities as well as some free cities.
Prussia became the defender of the western german boundary, and the king accepted the demands of Alexander I to cede the majority of his Polish possessions to Russia in return for a large part of Saxony.
