It extends the civil liberties provided in the US Bill of Rights to state governments.

Explanation:

The united states constitution and its amendments contained two things:

- the powers that can be enacted by the US government along with

- protection to citizens' basic rights written under the Bill of rights.

This created a question.

What would happen if in order to each the power of the government, they have to violate the rights of the citizen?

In early 1900s, the supreme court introduced the concept of selective incorporation to address this issue. According to this concept, the enactment of the government power under the constitution should be be incorporated selectively. They can be done as long as they do not violate the rights of the citizens.

Because of this, we can say that selective incorporation basically extends the civil liberties provided in the US Bill of Rights to state governments.
