What was the goal of th leaders who met at the congress of vienna in 1815

The meeting took place from September 18, 1814 to June 9, 1815. The conference was based on two major principles: the principle of monarchy of legitimacy and the principle of balance of power, being the main driver of the meeting the prince Klemens von Metternich, Minister of Foreign Affairs of Austria and distinguished diplomat of the time.

Thus, his intention was to return Europe to the situation before the French Revolution (1789), not only to restore the national borders deranged almost 20 years ago, but also to ensure a balance of power to avoid another series of armed conflicts at great scale, as were the previous French revolutionary wars and, later, the Napoleonic wars.

union blockade

explanation:

the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.

the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
