I removed the Italian Republic flag (of 1946) icon from the Infobox, in accordance with several sections of WP:ICON; specifically (quoting),
- Generally, flag icons should not be used in infoboxes, even when there is a "country", "nationality" or equivalent field: they are unnecessarily distracting and give undue prominence to one field among many....
- Flags make simple, blunt statements about nationality, while words can express the facts with more complexity. [Conversano was part of the Holy Roman Empire, the Kingdom of Naples, and the Kingdom of Italy. The Italian flag removed was that of the Republic of Italy, not created until 1946]....
- Do not rewrite history. Flags should not be used to misrepresent the nationality of a historical figure [including some bishops], event, object, etc. Political boundaries change, often over the span of a biographical article subject's lifetime. Where ambiguity or confusion could result, it is better not to use a flag at all, and where one is genuinely needed, use the historically accurate flag.
