Dune II came before both of them, but as far as I remember it wasn't a pure RTS, it had an adventure aspect as well.

The adventure game (with minor RTS elements) was Dune (no II) by Cryo. This one is Dune II by Westwood, which was a pure RTS.

Funny enough, they were developed at the same time.

You're absolutely right, thanks for refreshing my memory :)
