'''Categories''' are used in Wikipedia to link articles under a common topic and are found at the bottom of the article page. Clicking the category name displays a list of articles in that category, as well any sub-categories. Categories allow readers to navigate through Wikipedia and find related articles.

==Category tree==

All of the categories form a hierarchy, although sub-categories may be a member of more than one category. An example of a small part of this hierarchical structure is shown:

----

{| align="center"

|-

| rowspan=3| <small>[[:Category:History]]</small>

| rowspan=3| → <small>[[:Category:History by ___location]]</small>

| rowspan=3| → <small>[[:Category:History by country]]</small>

|-

| → <small>[[:Category:History of Australia]]</small>

| → <small>[[:Category:History of New South Wales]]</small>

|-

| → <small>[[:Category:History of the United States]]</small>

| → <small>[[:Category:History of California]]</small>

|-

|

|

|

| → <small>[[:Category:History of Zambia]]</small>

|}

The actual relationship can be a little more complex as a category may appear as a subcategory of several other categories.

</center>

The uppermost category in the hierarchy is [[:Category:Contents]]. From here all other categories branch out, including those that are used for the maintenance of Wikipedia.

If an entry in a category is shown in ''italics'' it is a redirect to an article of a different name that contains information about that particular subject.
