Explanation:

The Congress of Vienna (1814 - 1815) was held after the defeat of Napoleon. Its main goal was to restore the balance of power in Europe and put things back to how they were before the upheaval caused by the French Revolution (1789 - 1799) and the Napoleonic Wars (1803 - 1815). The nationalist revolution in Belgium happened in 1830, long after the Congress of Vienna. The establishment of a constitutional monarchy in France (July Monarchy) was in 1830, also after the Congress. The Polish revolutionaries' attempt to gain freedom from Russia (November Uprising) was in 1830 - 1831, post - Congress.

Answer:

before the French Revolution and Napoleonic Wars.
