This template creates a single succession box column for incumbents to be used with succession boxes. It is only meant to be used in the right column of succession boxes.

The format is {{s-inc|parameter=}}, where parameter= is replaced by one or more of the parameter names shown in the following table. The code without any parameters defaults to Incumbent.

current — Replaces Incumbent with Current holder
recent — Replaces Incumbent with Most recent
heir — Designates the heir of the current incumbent, thus allowing the succession chain to continue as a list of heirs
heir-type — Replaces "Heir" with the inserted text, preferably one of "Heir apparent", "Heir presumptive", "Coadjutor bishop"

Note: Template:s-ttl does not allow for a template to have an incumbent, so editors must add "– present" after the first date. If using the "recent" parameter, this is not necessary.

This template allows for multiple row-spans using the parameter |rows=| between the template name and the first parameter.

{{s-inc | heir = [[Charles, Prince of Wales]] | heir-type = Heir apparent}}
{{s-end}}
