**Abstract: **In this talk, we give the homotopical classification of principal bundles

in algebraic topology. For a topological group G, we show there is a classifying

space BG such that homotopy classes of maps form a space X to BG are in

bijection with isomorphism classes of principal G-bundles on X. In particular, we

focus on the general linear group where we describe the classifying space as an

infinite Grassmannian.
