Why is histamine released during an allergic reaction?

How does histamine play a role in allergic rhinitis?

Of the five cardinal signs of allergic rhinitis (pruritus, mucosal edema, sneezing, mucus secretion, and late-phase inflammatory reactions), histamine is capable of mediating the first three through its H1 receptor. In the nose, mucus secretion can be reflexively mediated by H1 and possibly also by H2 receptors.

Why do histamines make your eyes and nose itch?
