What is the K. K.K and why did this terrorist organization form in 1867?

The KKK is the KuKluxKlan

And they are white supremist and they Really HATE African americans. They even hate Jews, Immigrants, Gay people, muslims and Catholics.

I don't know why they formed so I will just copy and paste for this part- (i am very sorry)

In Pulaski, Tennessee, a group of Confederate veterans convenes to form a secret society that they christen the “Ku Klux Klan.” The KKK rapidly grew from a secret social fraternity to a paramilitary force bent on reversing the federal government’s progressive Reconstruction Era-activities in the South, especially policies that elevated the rights of the local African American population.

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.
