Template:Country establishment category by century/doc

Usage
'''


 * Examples

  – for Category:20th-century establishments in the United States

  – for Category:1st-century establishments in China

  – for Category:5th-century establishments in the Byzantine Empire

The 5th parameter is optional. If it is omitted, a parent category for the millennium will not be generated; e.g.   will not put the century category into the non-existent parent Category:2nd-millennium establishments in Aragon. Consensus at WP:CFD discussions points to not having millennium categories for territories that only existed during one millennium.

Parent categories
The template generates appropriate parent categories. One of these, "Establishments in [Foo] by century", is only generated if it exists; if it does not exist, the century category will be placed directly in "Establishments in [Foo]", e.g. Category:Establishments in the Burgundian Netherlands (see CFD discussion).

Table of decades and years
A table of decades and years will be produced if the century is 11th or later. This can be suppressed by appending the parameter

Note that categories for decades and years by country before the 11th century are generally deprecated following a series of CFD discussions in 2017, e.g. Categories for discussion/Log/2017 October 3.

However, decade categories were not merged for the Roman Empire or Byzantine Empire. To display a list of decade categories (but not years), append the parameter

Change of country name
From 2015 to January 2022, this template took an optional parameter for a new name of the country. That parameter is now obsolete, as the template makes use of category redirects instead.

If the default parent category "Establishments in 'X' by century" is a category redirect page, the template will resolve the category redirect, i.e. it will use the target page with the new name instead. Similarly, it will resolve a redirect on the millennium parent.

 
 * Example

The parent categories will be Category:Establishments in Myanmar by century and Category:2nd-millennium establishments in Myanmar, because the default category names Category:Establishments in Burma by century and Category:2nd-millennium establishments in Burma are both redirected to the corresponding names using "Myanmar".

To resolve links using redirects at every decade and year when an old country name was in use, use EstcatCountryCentury/resolve, e.g. as at Category:18th-century establishments in Siam.

Where a different result is desired, it may be best to create a specific template like those in Category:20th-century establishments templates by country. Some centuries in some countries have one-off tailored versions instead – see this template's talk page for examples.
