Template:Country disestablishment category by decade/doc

Usage
E.g.   for Category:1960s disestablishments in the Republic of Dahomey

Note: if any of the parent categories should use a different country name, simply set up a category redirect at the default name. E.g. Category:Disestablishments in the Republic of Dahomey by decade is redirected to Category:Disestablishments in Benin by decade, and as a result, the 1960s example above will take the Benin category as its parent, in place of the one that is redirected.
