Hello
The main reason behind the formation of North Atlantic Treaty Organization (NATO) was to defend themselves against Soviet aggression. It was a treaty that was created by United States of America along with Canada and several western European Nations. The treaty was created in the year 1949.
NATO was the first peace time alliance between several
countries along with United States of America. The Second World War had
devastated several European countries economically and they did not want the
Soviets to take advantage of this position.
Have a nice day
The main reason was the South wanted to preserve slavery. The North wanted to abolish it. If you want some other reasons than slavery, let me know, and I will do my best to add more to this answer.
