Hilbert schemes are moduli spaces of subvarieties, hence configuration spaces in algebraic geometry.
For instance a scheme of 0-dimensional sub-schemes is called a Hilbert scheme of points, etc.
Specifically for quasi-projective variety with fixed Hilbert polynomial?, Hilbert schemes are well behave as moduli spaces go, in that they’re actually quasi-projective varieties themselves.
The existence and construction of Hilbert schemes is due to Grothendieck (FGA).
The Hilbert scheme of $\mathbb{C}^2$ is widely studied in combinatorics and geometric representation theory for its connections to Macdonald polynomials and Cherednik algebras.
