Google "incorporation bill of rights".

Tldr, most of the bill of rights now applies to the states because of the 14th amendment.

While most states had similar/identical rights in their state constitutions, the incorporation of the bill of rights meant you citizens now have a minimum set of rights. The state could give you more rights, but at minimum you have these ones.

The biggest impact of incorporation, imo, is on the 4th amendment and the restrictions on searches and seizures. Example, Miranda v Arizona
