Is an 'Introduction' part of the 'Story'

My question is this: When submitting a prospective story would you include the 'Introduction' as part of the requested 'first three chapters' or '50 pages' (etc.) requested by an Agent/Publisher?

My reason is this: I have a rather lengthy introduction by both the Author (me) and the MC (fictional character). This introduction is, I feel, important to establish a specific 'attitude' that I wish to convey for the storyline. However, my story can stand alone without the introduction. I would like to keep the introduction in the final printing job, but for submission purposes, I don't feel like this is a strong point to begin with. My first three chapters (prelude, Ch1, Ch2) carry a moving and interesting 'hook' (so I hope). So when asked, should I not submit the Intro until I've gain interest with the Prelude, Ch1 & Ch2? (Then adding the intro after having gained the Agent/Publisher interest?)

We peons are greatly appreciative!

Do chapter 1, 2, 3. The introduction can go with the rest of the manuscript, later.

They want to see that you can write and tell a story, not introduce yourself and your story.

The intro is more about 'opinion' than me - the author. I hope it starts a 'tone' that the story follows. But I get your meaning, Thanks PeeDee.
