Abstract: Many of the fundamental manifolds arise as homogeneous spaces, but this class of manifolds is rather limited.
We discuss various ways in which one can define more general classes of manifolds, using Lie groups as a basic building block.
Such constructions give, among others, interesting examples of manifolds with non-negative curvature.
