  We define global Weyl modules for twisted loop algebras and analyze their
high- est weight spaces, which are in fact isomorphic to Laurent polynomial
rings in finitely many variables. We are able to show that the global Weyl
module is a free module of finite rank over these rings. Furthermore we prove,
that there exist injective maps from the global Weyl modules for twisted loop
algebras into a direct sum of global Weyl modules for untwisted loop algebras.
Relations between local Weyl modules for twisted and untwisted generalized
current algebras are known; we provide for the first time a relation on global
Weyl modules.
