In category theory, a branch of mathematics, a natural transformation provides a way of transforming one functor into another while respecting the internal structure (i.e. the composition of morphisms) of the categories involved. Hence, a natural transformation can be considered to be a "morphism of functors". Indeed this intuition can be formalized to define so-called functor categories. Natural transformations are, after categories and functors, one of the most basic notions of category theory and consequently appear in the majority of its applications.

“The remnant of Indians thereaboutall but exterminated in their recent and final war with regular white troops, a war waged by the Red Men for their native soil and natural rightshad been coerced into the occupancy of wilds not far beyond the Mississippi.”
