Cultural blending happens when dif. cultures interact with each other and mix. An example of this is the safavid empire. The Safavid empire grew from Persian, ottoman, and arab traditions. Blending begins at continental crossroads, trade routed/posts, and borders and is caused by migration, pursuit of religous freedom, trade, and conquest. Societies benefit only if they are willing to change and adapt. This leads to changes in language, religion, gov. styles, technology use, military tactics, racial or ethnic blending, and arts and architecture.
