what is the significance of the goths crossing the danube and why were they unlike other tribes that had come before them?

Goths were barbarian tribes.  

Explanation:      

In 376, the Goths arrived along the Danube River and appealed Flavius Valens (Roman emperor), for approving to cross the river and enter the Roman Empire. The purpose of asking permission to enter the Roman Empire was a concern of the Huns. Huns were nomads known for their brutal who placed a military pressure on the Goths as they began to move in the west direction.

The Goths first came to the Roman empire to seek shelter. At first, the relationship between the Romans and Goths was peaceable, but as the number of Gothic people increased, the Romans fought back. Goths fought against Romans in the late 300s A.D., that led to the downfall of the Roman Empire.

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.
