This subtemplate of {{Infobox country}} is used to automatically add categories to articles which transclude this template. It should not be used directly

Establishment dates

• First the template tests to see if "Category:States and territories established in the {{{year_start}}}" exists. If so, it is added.
• If not, the template tests to see if "Category:States and territories established in {{{year_start}}}" exists. If so, it is added.
• If not, the template tests to see if "Category:States and territories established in the DECADEs" where DECADE is the decade containing {{{year_start}}} (ie Nodyn:Cl). If so, it is added.
• If not, the template tests to see if "Category:States and territories established in the Nth century" where N is the century containing {{{year_start}}} (ie Nodyn:Cl). If so, it is added.

The reason for the first case is in case an imprecise date is imputed, such as "the 820s" or "the 18th century", before trying exact dates like "1820".

Disestablishment dates

• First the template tests to see if "Category:States and territories disestablished in the {{{year_start}}}" exists. If so, it is added.
• If not, the template tests to see if "Category:States and territories disestablished in {{{year_start}}}" exists. If so, it is added.
• If not, the template tests to see if "Category:States and territories disestablished in the DECADEs" where DECADE is the decade containing {{{year_start}}} (ie Nodyn:Cl). If so, it is added.
• If not, the template tests to see if "Category:States and territories disestablished in the Nth century" where N is the century containing {{{year_start}}} (ie Nodyn:Cl). If so, it is added.
