This template is intended to be used for all-Ireland instances, usually resulting in a wikilink to جزیره ایرلند (article about the island) instead of ایرلند (article about the sovereign nation).

However, it is often convenient to use ((flagicon|Ireland)) and ((flag|Ireland)) instead of ((flagicon|Republic of Ireland)) and ((flag|Republic of Ireland)) respectively, so this template differs from the standard format in order to accommodate that usage. The alias parameter changes depending on whether or not a flag variant is used by the parent template call:

alias = ((#if:(({variant|))}|Ireland|Ireland (state)))

This results in

• ((flag|Ireland|1783)) →  ایرلند جومهوریتی (use for Ireland as part of پادشاهی متحد بریتانیای کبیر و ایرلند)
• ((flag|Ireland)) →  ایرلند (use for current state)

Also, several sport-specific flag variants are maintained here, and these are automatically used by the respective sport team templates:

• ((fb|Ireland)) →  ایرلند (football, 1882–1922)
• ((fh|Ireland)) →  ایرلند (field hockey)
• ((rl|Ireland)) →  ایرلند (rugby league)
• ((ih|Ireland)) →  ایرلند (ice hockey) — all-Ireland team that uses the tri-colour
• ((ru|Ireland)) →

دیل کودو اعتیبارسیز دیر. (rugby union)

• ((cr|Ireland)) →  ایرلند (cricket)

The standard country code for the Republic of Ireland is IRL, so it can be used as an alias for Template:Country data Republic of Ireland. The non-standard country code IRE is used as an alias for this template to provide similar convenience. For example:

• ((flagicon|IRL)) →
• ((flagicon|IRE|1783)) →
• ((flagicon|IRE|4prov)) →
• ((fb|IRL)) →  ایرلند (links to تیم ملی فوتبال جمهوری ایرلند)
• ((fb|IRE)) →  ایرلند (links to Ireland national football team (1882–1950))

Do not use the IRL alias for all-Ireland sports team, and do not use the IRE alias without a flag variant specified. The following examples should not be used.

• ((flagicon|IRE)) → (Works, but better to use the standard country code for IRL.)
• ((fh|IRL)) →  ایرلند (Use ((fh|IRE)) instead)

Country_data templates are also available for each of the four traditional provinces of Ireland:
