Abstract: Langlands decompositions of affine Kac-Moody algebras have been obtained by the method of direct determination as introduced by Cornwell for Lie algebras. This method is particularly helpful in the case of lower rank algebras. The involutive automorphisms required for such a study are obtained from the Satake diagrams of the corresponding algebras. This has been well illustrated by taking A(1) 3 (untwisted) and A(2) 4 (twisted) as representative examples.
