Because they helped strengthen their industrial-based economy
Some ways that slaves resisted slavery was by rebelling, being less productive at work, stealing from their owners, and sometimes actually harming their owners (or just other white people). The slaves demonstrated a sense of semi-independence or self- worth through having their own subculture with their own unique music, having a religion and their own churches to tie them together, as well as celebrating their African roots and traditions. Slave masters allowed some of these behaviors so as to avoid their slaves becoming really aggressive towards them, as well as giving the slaves some "freedoms" encouraged and motivated slaves so they didn't get too hostile.
Answer:
In 1949, the prospect of further Communist expansion prompted the United States and 11 other Western nations to form the North Atlantic Treaty Organization (NATO). The Soviet Union and its affiliated Communist nations in Eastern Europe founded a rival alliance, the Warsaw Pact, in 1955. Joining the USSR in the alliance were Albania, Bulgaria, Czechoslovakia, the German Democratic Republic (East Germany), Hungary, Poland, and Romania. This lineup remained constant until the Cold War ended with the dismantling of all the Communist governments in Eastern Europe in 1989 and 1990. Initial member-states of the North Atlantic Treaty Organisation (NATO) included the United States and all five Brussels treaty nations, Canada, Denmark, Iceland, Italy, Norway, and Portugal. Several countries were invited to join NATO but refused, including Finland, Ireland, Sweden, and the ever-neutral Switzerland.
NATO favored capitalism and the USSR favored communism. These alliances rivaled each other and fought for dominance. NATO ended up coming on the top to save capitalism.
