{{High-use}}

This template is used to display a small flag icon next to an '''unlinked''' country name.  It is an alternative to the {{tl|flag}} and {{tl|flag country}} templates, for use in instances where the country name should not be linked, per [[WP:OVERLINK]].

See [[Wikipedia:WikiProject Flag Template]] for the main documentation/discussion page for the flag templates system.

==Usage==
: '''<nowiki>{{Flagu|</nowiki>'''''country identifier'''''&#124;'''''optional variant'''''<nowiki>}}</nowiki>'''

*''country identifier'' is the common name of the country (e.g. "United States"), a common alias (e.g. "US"), or a standard country code such as those listed at [[ISO 3166-1 alpha-3]]
*''variant'' is an optional second parameter that can be used to display a flag variation, such as a historical flag.  The list of variants for each country is documented on the appropriate template page, such as [[:Template:Country data Germany]]

See <span class="plainlinks">[https://en.wikipedia.org/w/index.php?title=Special%3APrefixindex&from=Country+data&namespace=10 the prefix index]</span> for the templates latently called by this one.

==Examples==
{| class="wikitable"
! Wiki markup !! Displays
|-
| <code><nowiki>{{Flagu|Germany}}</nowiki></code> || {{Flagu|Germany}}

==Alternatives to avoid Wikipedia's [[WP:PEIS|Post-expand include size]] limit==
Pages with many flag icons may come close to or exceed Wikipedia's [[WP:PEIS|Post-expand include size]] limit.  In these cases consider using modules or module-wrapper templates instead:
* {{template link|flagg}} is a simple wrapper for [[Module:Flagg]]: For basic use, <code><nowiki>{{flagu|</nowiki>''country''<nowiki>}}</nowiki></code> can be replaced with <code><nowiki>{{flagg|unu|</nowiki>''country''<nowiki>}}</nowiki></code>
* {{module link|flag|u}} is a wrapper for [[Module:Flagg]] that can further reduce sizes when invoked directly. For basic use, <code><nowiki>{{flagu|</nowiki>''country''<nowiki>}}</nowiki></code> can be replaced with <code><nowiki>{{#invoke:flag|u|</nowiki>''country''<nowiki>}}</nowiki></code>.
