Why is the taj mahal a good example of cultural diffusion

The Taj Mahal a good example of cultural diffusion because it contributes to the spread of social activities and cultural beliefs from one country to another. It also mixed different cultures all over the world through religions, nationalities, ethnicities, and others. It is a good example of cultural diffusion because it unites cultures with their ideas, customs, and practices. Taj Mahal was built to be a tomb for the wife of Shah Jahan, Mumtaz, who died when she gave birth to their 14th child. 

It taught people how to live a good life, but not what to believe.
