America is known to be subcontinent. But since they knew they hated the British as well as the french they sided with them but this got them a REP of fighting to the British; thus starting the revolutionary way. Hope this helps!!
One development was mass secularization. People abandoned the idea of there being a god and turned more and more towards atheistic or agnostic beliefs. This was highly problematic for western thought which was commonly very theistic and its ethics were often based on concepts from religion and with loss of this the western thought was endangered.
Another is that nihilism started developing. Nihilism is the concept that life in itself is meaningless and that there is nothing truly to strive for or do since there is no true meaning to be found in it other than the meaning that we ascribe to it which is not true since it was created by us and not by a higher power.
Another was scientific development of the atoms and theory of atoms. These developments very soon started getting weaponized and this led to the nuclear bombs which put the entire world in a crisis and on the brink of war, not just western thought. This also sparked numerous new ideas regarding ethics and morality.
Another was the development of Freudian psychology and psychoanalysis. This led to a crisis because it explained that people are not truly responsible for what they do but that they are guided by their subconscious and it is not something that we can explain. This led to numerous ideas regarding concepts of free will.
"Saved by an Indian Maiden"
"The story begins when Smith and two English companions are ambushed by Indians. After killing his two companions, the Indians take Smith to their chief, Powhatan. After two months in captivity, Powhatan determines to have the Englishman clubbed to death in a ritual ceremony. According to Smith, the plan is thwarted only when the chief's daughter, Pocahontas (then aged 11 or 12), throws herself between him and his attackers causing her father to relent. Smith published his account of the incident in 1624. It is the only description of the event we have and some historians doubt its authenticity. However, the account permanently etched his name in American folklore."
