How did military expanion bring about an increase in the social status of roman women?

The military expansion helped women by gaining more rights due to the wealth accumulated during the military campaigns of the Roman army.  It also led to the abolition of the Oppian Law that forbade women to flaunt their riches.  Women later gain the right to divorce their husbands They can also own business and slaves as well as draw wills and run households.
