In the late 1950s, an important problem in number theory was to extend the notion of `$L$`

-functions attached to cuspforms on the upper-half
plane to automorphic forms on reductive groups. Langlandsâ€™s work on non-abelian Harmonic analysis, namely the problem of the spectral decomposition of automorphic forms, led him to a general notion of `$L$`

-functions
attached to cuspforms. We give an introduction to the spectral decomposition of automorphic forms and discuss some contemporary problems.
