How are all courts, except the us supreme court, established?

The United States is considered to have a dual court system, since it has both a federal judiciary and state judiciaries. State courts are established by each state, and these vary from state to state. Each of these courts, federal and state, have specific jurisdictions and operate at the same time, and sometimes, the federal and state courts have shared jurisdiction (concurrent).

Thnxs for the points. Have a good day :)

here is the answer to your question

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.
