What is the name for the way in which different religious or philosophical beliefs are blended together, as exemplified by the architectural style of angkor wat?

Syncretism is the combining or blending of beliefs and practices from different schools of thought, commonly in ethics, religion, and philosophy. It involves the merging or assimilation of different traditions originally thought to be discrete, and allows for unification and an inclusive approach to various beliefs and practices. When applied to arts and culture, syncretism is most commonly called "eclecticism," and when applied to politics, "syncretic politics."
