How do you explain the rise and fall of the kkk in different periods of the U. S. history?

The Ku Klux Klan (KKK), a racist and violent organisation that massed as many as two million members in the 1920s, casts a long shadow over US history.

Founded in 1866 in the state of Tennessee, it brought together a small number of apologists for US slavery who took part in showy rituals bearing flaming torches, and wore white hoods and gowns often decorated with astrological signs.

The following year, the Klan became a paramilitary force under former Southern officers such as General Nathan Bedford Forrest, the first Grand Imperial Wizard of the so-called invisible empire.
