Was there ever a case when Rome conquered a territory solely for the purpose of gaining control of a specific resource (spice, ore, timber, etc....)?
I'm looking for something backed up by historical evidence - e.g. a document from a military/civilian leader, a public speach etc... admitting to such motivation.
Please note that I'm only including extractable natural resources here as understood today - e.g things like slaves, extra economy, markets, waterways or strategic territory are NOT in scope.
