From Wikipedia

Human societies are characterized by patterns of relationships between individuals sharing a distinct culture and institutions. Without an article, the term refers either to the entirety of humanity or a contextually specific subset of people.

I would be inclined to restate my own question as’society’
(without “the”) refers to human society in general, and, the

example should read “socialization is
the process of learning to live in society” The phrase

“the society” is used in areas of study such as anthropology, political science and sociology when referring to specific groups.

From Wikipedia, talking about any particular group. This noble

organized warriors to protect the society to avoid invasion.

In this case, “the society” is used to limit the scope to the group under discussion, not to all humanity.

In “fighters protect society” the lack of an article

preceding “society” makes it a statement about human society in general. When an idea is conceptually feasible, it would stand alone without any other context.

“Soldiers protect the society” seems taken out of context. In what society is the answer to this question?

Why are the following examples not history fact?

In ancient Rome, soldiers called centurions protected the (Roman) society.
In ancient Japan, soldiers called samurai protected the (Japanese) society.
