Final answer:
The imposition of Western nations' products and beliefs on less powerful nations is known as imperialism, which involves controlling and influencing these nations politically, economically, and culturally.
Step-by-step explanation:
When influential nations of the West impose their products and beliefs on less powerful nations, this is called imperialism. Imperialism is a policy or practice by which a country increases its power by gaining control over other areas of the world. This dominance is achieved through direct conquest, economic control, and cultural influence. Historically, Western nations have exerted such influence by introducing their own cultural practices, such as language, education, religion, and lifestyle, into the countries they colonized or controlled. They have also extracted resources from these nations and sold their manufactured products back to them, often undermining local economies and traditional ways of life.
