How did bourbon democrats prevent populists from gaining political power in louisiana

The Bourbon Democrats prevented the populists from gaining political power in Louisiana by refusing to double the standard of money in silver.

Explanation:

Keeping the gold standards of money intact without introducing silver standards of money, the Bourbon Democrats ensured that the populists were short of money and thus refrained from running in gaining political power in the long term.

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.

the government closely monitored its finances to avoid another financial collapse.
