Today we use [[ https://www.wikidata.org/wiki/Property_talk:P571 | P571 ]] "//date or point in time when the organization/subject was founded/created//"
maybe we should change to [[ https://www.wikidata.org/wiki/Property_talk:P580 | Property:P580 ]] "//indicates the time a statement starts being valid//"
see
* {T200500}

=== Advice ===
Using //somedate// is not a good advice we need to specify what "medivial time is" see [[ https://www.wikidata.org/wiki/Wikidata:Project_chat#Add_a_date_before_year_1600_? | Wikidata:Project_chat#Add_a_date_before_year_1600_? ]]
