Use this to create a category of the form "YYYY crimes in CountryName", where "CountryName" is a valid name of a country and "YYYY" is a 4-digit year.
e.g.
- Category:1860 crimes in the United States
- Category:1932 crimes in Japan
- Category:2011 crimes in Pakistan
- Category:2015 crimes in Nigeria
Usage
Normal usage
{{YYYY crimes in countryname category header}}
The normal usage requires no parameters, because the template looks up the other data.
e.g. on Category:1954 crimes in the United States, no parameters are needed
The other needed data is:
- the adjectival form of the country in which the country is located. This is looked up by Template:GetAdjectiveFromCountryName and adds a parent category e.g. Category:1954 in American law if that exists
- the continent(s) in which the country is located. This is looked up by Template:Country2continent
If either of those lookups fails, then an error is reported unless the required data is supplied by an optional parameter.
That may be due to this category being misnamed, or it may be due to an omission in the lookup table used by Template:GetAdjectiveFromCountryName or Template:Country2continent. (Some former countries may have been omitted. Also, when country has been renamed, the lookup uses only the current country name).
If a lookup fails, then the template creates no output other than an error message. If you are satisfied that the category is correctly named, use the one of the optional parameters below.
Optional parameters
|nationality=Fooishbypasses the lookup of the nationality, and uses "Fooish"|continent1=Atlantisbypasses the lookup of the continent, and uses "Atlantis".|continent2=Lemuriabypasses the lookup of the continent, and adds a second continent: "Lemuria"|parentcountry=AnotherCountryis available for use when a country is part of another country.
e.g. on Category:2003 crimes in Hong Kong, use{{YYYY crimes in countryname category header|parentcountry=China}}|diagnose=yesturns on diagnostics, which may help if the template doesn't work as expected
Tracking
Use of the |parentcountry= parameter is tracked in:
Use of the |nationality = parameter is tracked in:
- Category:Template YYYY crimes in countryname category header with nationality parameter (population 0)
Categories where country lookup fails are tracked in a category shared with many other templates:
- Category:Errors reported by other category header templates (population 1)
