I think the Ku Klux Klan formed because of racism. Some white people really hated black people, so they started a clan (Ku Klux Klan) to kill and torture blacks. At the end they would put them up on a cross and set it on fire.
The Ku Klux Klan (/ˈkuː ˈklʌks ˈklæn, ˈkjuː/),[a] commonly called the KKK or the Klan, is an American white supremacist hate group[8] that was founded in 1865 during the Reconstruction era. The Klan has existed in three distinct eras at different points in time during the history of the United States. Each has advocated extremist reactionary positions such as white supremacy, white nationalism, anti-immigration and—especially in later iterations—Nordicism[9][10] and anti-Catholicism. Historically, the KKK used terrorism—both physical assault and murder—against groups or individuals whom they opposed.[11] All three movements have called for the "purification" of American society and all are considered right-wing extremist organizations.[12][13][14][15] In each era, membership was secret and estimates of the total were highly exaggerated by both friends and enemies.
The differences between the two countries stems from their ideologies. Communism was the ideology followed by the Soviet Union while capitalism was the ideology of the US
