Why aren't state agencies considered "persons" for Section 1983 claims?

What is the name of your state (only U.S. law)? federal court

State agencies are not considered "persons" for the purposes of violations of 42 U.S.C. 1983. Why not? Why aren't they considered corporate persons?

If they can sue, why shouldn't they have the right to be sued, provided that you can get around sovereign immunity?

All the court decisions that I have read have provided no explanation, whatsoever, for why they hold this policy. None. None at all.

There has to be some reason.

Furthermore, is there a Supreme Court case that actually states this?

Can you provide an example of one of these cases?

EDIT: Or, how about this link?

http://www.constitution.org/brief/forsythe_42-1983.htm

It states that states and state agencies are immune from suit, yet, when I click on the [6] to take me to the source it is citing, it only says "Id." It tells me absolutely nothing about where they actually got this information.
