Template:Infobox former country/doc

This template provides comparative information for countries which no longer exist.

Usage

 * 1) Almost all fields are optional, some fields are more optional than others. It is not expected that you fill in every single field that is shown here.
 * 2) Some fields are hidden but necessary for infobox functionality. Not all fields are displayed here.
 * 3) If a state has a high number of leaders (>5), do not modify this template to fit them all in. It is not the  intention of this infobox to do them all — that makes the infobox way too big (any extra slots added here without previous discussion will be reverted). Instead, list only the first and last title holder, with (first) or (last) placed after the person's name.
 * 4) Some fields place the article into certain categories: see list of supported categories.
 * 5) Area (in km2) and population statistics must be given without spaces, commas or other code.
 * 6) Keep event text as short as possible — ideally only 1 line in length.
 * 7) For many entries, the infobox has been implemented by one of the main developers. Other users are welcome to implement the infobox themselves, but developers might make modifications later on — largely for functionality reasons.
 * 8) If you are unsure about the usage of this template, or if you want to know why a certain modification was made, let us know via the template talk page. Your comments and questions assist the developers in creating, improving and documenting infobox features.

Detailed instructions
These are the fields of information in the Infobox former countries template with a set of instructions on how to use them. Here is a brief explanation on how to read the table:


 * Field name
 * the fields of information that carry information used by the template
 * Usage
 * required means that the template will not work properly if it is excluded
 * optional means that the template will work properly with out it, but available information should be entered to make it as complete as possible (actively excluding or deleting information is not endorsed because it is called optional in this table)
 * Type
 * variable means that the template will only take fixed values; this can be dates, years, numerical or according to a defined list
 * free means that the template will accept values given freely without having to adhere to the strict discipline required for variables
 * wikilink means that a working wikilink must be entered either to an article or to the file name of an image
 * Value
 * examples or lists of values accepted by variables
 * free text with wikilinks means that text and wikilinks can be entered freely with out the kind of restrictions that applies to variables
 * label is a short label typically fitting in a single line (no line break)
 * entry is one or a few short labels separated by commas or line breaks (no more than a few lines)
 * sentence is a short descriptive sentence (no more than a few lines)
 * free text means that text can be entered, but wikilinks must not be used
 * Description
 * an instruction or a small guide how the particular field of information is used

Name

 * style="background-color: whitesmoke;" | Field Name
 * style="background-color: whitesmoke;" | Usage
 * style="background-color: whitesmoke;" | Type
 * style="background-color: whitesmoke;" | Values
 * style="background-color: whitesmoke;" | Description
 * - valign=top
 * native_name || optional || free || label (free text) || Name in native language(s), displayed at the top of the infobox. If there are multiple native languages, separate different names with line breaks. If the native language is English, leave this section blank and give the name in the next field.
 * - valign=top
 * conventional_long_name || required || free || label (free text) || Full name in English, displayed under the native name
 * - valign=top
 * common_name || required || variable || "country name"
 * This variable is a supporting variable for the infobox. The value required here is not always historically factual but this variable is very important as it has a number of important uses:
 * The value here determines how the entry is indexed within the categories that the infobox generates.
 * Example: The "Kingdom of England" should be indexed under E (England) instead of K (Kingdom). Therefore, "common_name=England"
 * Various links within the infobox are automatically generated if a certain page exists. If the article does not exist, a more generic link is produced. If the entity discussed is normally preceded by "the" (eg. the United Kingdom), do not enter "the" in common_name: the template will also search for such links.
 * Example: The flag and heraldry information for Croatia over its history are in the two articles "Flag of Croatia" and "Coat of arms of Croatia". By saying "common_name=Croatia", the text underneath the flag and coat of arms images automatically links to these entries. For the Axis-controlled Independent State of Croatia, saying "common_name=Independent State of Croatia", while historically accurate, does not generate these links because there are no "Flag/Coat of arms of (the) Independent State of Croatia" articles.

 * - valign=top
 * empire || optional || variable || "country name" || Give the "common name" for the imperial country to which the entity was in a state of dependency.
 * Example: British Empire colony: "status=Colony", "empire=United Kingdom"
 * - valign=top
 * status_text|| optional || free || label (free text with wikilinks) || If values are given for status and empire, it will be displayed by default as "status (empire)".

Politics

 * style="background-color: whitesmoke;" | Field Name
 * style="background-color: whitesmoke;" | Usage
 * style="background-color: whitesmoke;" | Type
 * style="background-color: whitesmoke;" | Values
 * style="background-color: whitesmoke;" | Description
 * - valign=top
 * government_type|| required || variable ||
 * Monarchy
 * Constitutional monarchy
 * Principality
 * Republic
 * Socialist republic
 * See also the variable status and the categorization scheme.
 * This entry generates more categories and sets some defaults for other political titles (see below). If the value given here does not match any in the following list, the article will be placed in the maintenance category for further examination. If a change in government takes place without the country itself changing, place the earlier government type in this field, and give the change in government as an intermediate event (eg. event1).
 * - valign=top
 * colspan=5 style="background-color: whitesmoke;" | Head of state
 * - valign=top
 * title_leader || optional || free || label (free text with wikilinks) || the head of state's title. If "government_type" is "Monarchy" or "Constitutional monarchy" monarchy, the default "King" will be displayed, which will link to "King of {common_name}" if that article exists. If "Republic" of "Federal republic" is given, "President" will be used instead. If a different title is used, enter it here (but keep the length to a minimum) and wikilink it to the relevant article (if any)
 * Example: For the Kingdom of Prussia, "government_type=Monarchy" but "title_leader" has not been given. This is because the article "King of Prussia" exists, and is automatically linked to from the default word "King" in the infobox.
 * Example: For the German Empire, the Emperor was also the King of Prussia. But instead of giving a title of "Emperor of Germany, King of Prussia", Emperor is used instead, which includes a link to all German monarchs
 * - valign=top
 * leader1, leader2, ... || optional || free || label (free text with wikilinks) || Leader name. Wikilinks are generated automatically, but you should create wikilinked entries for people whose entry title is long (this applies to almost all royalty).
 * Example: George III instead of "George III" or "George III of the United Kingdom". If it is not obvious that British monarchs are involved in this case, give the full "George III of the United Kingdom" (eg. Congo Free State).
 * - valign=top
 * year_leader1, year_leader2, ... || optional || free || label (free text with wikilinks) || Dates spanning rule of leader (eg. 1801-1843).
 * Note: If there was only one head of state, just fill in "leader1" but not "year_leader1". It is also not intended here to list every head of state that ever was: if there were a lot of them, just list the first and the last. To assist this, each name could be followed by (first) and (last) — but then you will need to wikilink the name.
 * - valign=top
 * colspan=5 style="background-color: whitesmoke;" | Colonial governor, representative of head of state, etc.
 * - valign=top
 * title_representative || optional || free || label (free text with wikilinks) || same as for the head of state. These fields are to be used for colonial governors, representatives of the head of state, etc. For heads of government (eg. Prime Minister), use the "deputy" field below
 * - valign=top
 * representative1, representative2, ... || optional || free || label (free text with wikilinks) || Representative name. Wikilinks are generated automatically, but you should create wikilinked entries for people whose entry title is long
 * - valign=top
 * year_representative1, year_representative2, ... || optional || free || label (free text with wikilinks) || Dates spanning rule of the representative (eg. 1801-1843).
 * - valign=top
 * colspan=5 style="background-color: whitesmoke;" | Deputy, head of government, etc.
 * - valign=top
 * title_deputy || optional || free || label (free text with wikilinks) || same as for the head of state. The only difference here is the default labels given: instead of "King" the default here is "Prime Minister"
 * - valign=top
 * deputy1, deputy2, ... || optional || free || label (free text with wikilinks) || Deputy name. Wikilinks are generated automatically, but you should create wikilinked entries for people whose entry title is long

 * style="background-color: whitesmoke;" | Usage
 * style="background-color: whitesmoke;" | Type
 * style="background-color: whitesmoke;" | Values
 * style="background-color: whitesmoke;" | Description
 * colspan=5 style="background-color: whitesmoke;" | Start and end
 * - valign=top
 * year_start, year_end || required || variable || year || Years of establishment and disestablishment. These years will be placed in the date bar at the top. If the values given are the same year, only one year will be displayed, but you must still enter both. Do not wikilink these years. The years given here are automatically used to assign this entity to establishment/disestablishment categories.
 * - valign=top
 * date_start, date_end || optional || variable || date || Give the day and month (if known) to match year_start and year_end. Do not wikilink these dates. The year_start and year_end fields must be filled in.)
 * - valign=top
 * event_start, event_end || optional || free || label (free text with wikilinks) || Entering the information for the above 4 variables (or just the year variables) will create entries in the "History" section of the infobox. If nothing is given for event_start or event_end, the events will have the corresponding default text of "Established" and "Disestablished", respectively. The variables event_start and event_end allow you to give more detail. If the value you enter is the name of an article, the wikilink is automatically generated. You are encouraged to link to the article that describes the actual event which caused the formation/dissolution of the entity, if such articles exist. To keep the infobox tidy, create a wikilink to the event article if the title of the linked article is long (eg. Established ). You are discouraged from simply entering something like "Declaration" or "Proclamation" in these fields, because there are general articles with this title.
 * - valign=top
 * life_span || optional || free || label (free text with wikilinks) || Some entities temporarily ceased to exist before re-establishing. Use this variable only for these entities to replace the displayed dates in the date bar. Give unlinked dates with line breaks. (eg. 1841 — 1899 1910 — 1967). You still need to fill in the year_start and year_end fields (in this example, "year_start=1841" and "year_end=1967") for the above-described functions to work.
 * colspan=5 style="background-color: whitesmoke;" | Events
 * - valign=top
 * era || optional || variable ||
 * Napoleonic Wars
 * World War I
 * World War II
 * Cold War
 * A category-assigning variable. If the value given here does not match any on the list in this table, this article will be automatically assigned to a maintenance-category. Do not panic. If a certain "era" value is used often enough, a new category will be created by the infobox developers.
 * - valign=top
 * event1/date_event1, event2/date_event2, ... || optional || free || label (free text with wikilinks) || Intermediate events. These will be listed in the History section between the start and end events. The event variables here function the same way as the event_start/event_end variables. Enter date as unlinked text (eg. "3 August 1789" or "3 August 1789" ).
 * - valign=top
 * event_pre/date_pre, event_post/date_post|| testing || free || label (free text with wikilinks) || Sometimes, events that take place outside the life-span of the entity are important, these two varaibles will place an event before event_start (pre) or after event_end (post) in the History box.

Preceding and succeeding entities

 * colspan=5 | These fields are optional, but very important. Entries here affect the flag-navigation feature of the date bar at the top of the infobox.

 * style="background-color: whitesmoke;" | Values
 * style="background-color: whitesmoke;" | Description

 * - valign=top
 * s1 – s5 || optional || wikilink || "country name" || Names of succeeding entities (up to 5)
 * - valign=top
 * flag_p1, flag_p2, ... || optional || wikilink || file name || Name of image of flag for the state corresponding to p1, p2,... (just the name, no Image: coding). If the preceding state had multiple flags during its existence, use the last flag that it used. The template is instructed to search for possible flag images given the name of the state, so it might not be necessary to fill in this field. If a flag is not found or defined, the default "flag unknown" image will be shown.
 * - valign=top
 * border_p1, border_p2, ... || optional || yes/no || yes or no or blank || Set to no to turn off border around the flag, for example for Nepal.
 * - valign=top
 * flag_s1, flag_s2, ... || optional || wikilink || file name || Name of image of flag for the state corresponding to s1, s2,... (just the name, no Image: coding), same as the flags for previous states. If the suceeding state had multiple flags during its existence, use the first flag that it used.
 * - valign=top
 * border_s1, border_s2, ... || optional || yes/no || yes or no or blank || Set to no to turn off border around the flag, for example for Nepal.
 * - valign=top
 * image_p1,image_s1,... || optional || wikilink || file name || Going further back in history, flags were less common and coats of arms were used instead. Coat of arms images are generally narrower than flag images, so if coat of arms images are displayed at the defined image size used here for flags (i.e. width=30px), they appear too big. Therefore, if you have anything other than a flag/banner image to use for a previous/following entity, fill in this field. Here you must enter all wikilinking as normally done when entering an image, but set the image width to 20px (or higher, depending on the individual image).

To which entries should I link?
It is not the intention here to list every single previous/following entity – that would make the infobox look very silly in many cases. Here are some guidleines for what to do (and what not to do). There are no strict rules so please exercise caution and common sense when using this feature.
 * 1) For most cases, the main and/or official predecessor/successor (under international law) is sufficient, since that is what most readers would expect to see. In the case of any potential confusion, list only this.
 * 2) *Example: not every single state formed after the breakup of the Ottoman Empire should be listed in the infobox for the Ottoman Empire. Such a list is better described in the article text. Instead, only the official successor state would be given (Turkey)
 * 3) In some cases, most readers would expect to see every state that was formed, not just the official predecessor/successor. If so, list all states. If only parts of other countries were taken to form the new entity (or if an already existing entity received some of the land from a dissolved entity), list these states only when there are not so many other states to list.
 * 4) *Example: the official successors of Austria-Hungary would be only Austria and Hungary. But from the breakup of Austria-Hungary, two other new states were completely formed (Czechoslovakia and the State of Slovenes, Croats and Serbs), one state was formed from part of Austria-Hungary (Poland, including territory ceded from Germany and relinquished from Russian rule), and two already-existing states gained territory from Austria-Hungary (Italy and Romania). This gives a total of 7 successor states, which is rather high. In order of priority, the states listed should be: [Austria and Hungary], [Czechoslovakia and the State of Slovenes, Croats and Serbs], [Poland], and finally [Italy and Romania].
 * 5) Do not list entities that were formed/dissolved outside the life-span of the discussed state.
 * 6) *Example: the breakup of the Socialist Federal Republic of Yugoslavia does require the listing of all countries involved, since that is what people would expect. But only the states formed at the time when the SFYR broke up should be given. Therefore, "Serbia and Montenegro" is a successor entity, not "Serbia" and "Montenegro" separately since that breakup occurred later.
 * 7) If an entity simply became a subdivision of another country (state, province, etc.), then link to that subdivision. Only do this if it the transition is very clear.
 * 8) *Example: the Republic of Texas was annexed by the USA and reconsituted as the US state of Texas. The successor here is not the USA, but the modern state of Texas.
 * 9) If the entity did not exist for a period before reforming (specified when you use the life_span parameter above), do not list the intermediate states.
 * 10) If the predecessor and successor are the same, and this predecessor/successor continued to exist during this period, do not list either. Instead, make it clear what this state was somewhere in the events section (if necessary).
 * 11) *Example: the Confederate States of America broke away from the United States of America before becoming again part of the USA after the American Civil War. Detailing predecessor and successor states here as the USA is redundant, since the USA still existed in some form during this period, so say nothing.

 * - valign=top
 * stat_year1, stat_year2 ...|| optional (required if area or population is given) || variable || numerical || rowspan=3 | It is possible to add multiple values for area and population over time.
 * Area must be given in km² without commas or any other spacing. The area in sq.mi. will be automatically calculated
 * Population must be given without commas or any other spacing. If area is also known for this time, population density will be automatically calculated.
 * Even if the area does not change over time, it should always be added along with any new population values in order to calculate density.
 * Example: You have population values for 1800 and 1900. You also have an area value and you know that it is the same for both years. You enter "stat_year1=1800" and "stat_year2=1900" and the two population values (without commas or spacing) under "stat_pop1" and "stat_pop2". You then enter your area value (in km², without commas or spacing) in both "stat_area1" and "stat_area2". The area will not be displayed twice, but the population density will be calculated for both years.

Style parameters
The template allows some optional parameters that control the style of the infobox, for size and coloring, when displayed on a page:
