Answer:
Syncretism.
Step-by-step explanation:
Syncretism may be a combination of separate concepts into one new, unique idea. It is seen to try in many cases to combine, reconcile and unite opposing parties, opposing principles, religions and other drifting forces.
It is when a side of two or more distinct cultures blend together to make a replacement custom, idea, practice, or philosophy. Cultural syncretism can occur for several reasons, from immigration to military conquest to the marriages between groups, and ends up in a culture finding ways to blend new customs into their own.
