The American colonies chose to declare independence from Great Britain for many reasons. They believed the British were treating the colonists unfairly. The British passed many tax laws that impacted the colonists. The colonists had no representatives in Parliament to vote on or discuss these laws.
The immediate cause was because President Carter decided to allow Iran's desposed Shah into America so he could receive cancer treatment.

unable to scrape up money for their next meal. Breadlines and soup
kitchens were established as charitable organizations giving free bread and
soup to the impoverished.
