. It is proved that non-trivial normal abelian subgroups of the Galois group of the maximal Galois p -extension of a field F (where p is an odd prime) arise from p -henselian valuations with non- p -divisible value group, pro-vided #( ˙ F/ ˙ F p ) ≥ p 2 and F contains a primitive p -th root of unity. Also, a generalization to arbitrary prime-closed Galois-extensions is given.
