Editing Adelaide of Italy (section)

===Later years===
Adelaide resigned as regent when Otto III was declared to be of the legal majority in 995. From then on, she devoted herself exclusively to her works of charity, in particular to the foundation and restoration of religious houses, i.e. monasteries, churches and abbeys.<ref name="Lawler2018">{{cite book|author=Jennifer Lawler|title=Encyclopedia of Women in the Middle Ages|url=https://books.google.com/books?id=pAxeCgAAQBAJ&pg=PA11|accessdate=29 July 2021|date=16 January 2018|publisher=McFarland|isbn=978-1-4766-0111-3|page=11}}</ref><ref name="Rose1857">{{cite book|author=Hugh James Rose|title=A New General Biographical Dictionary|url=https://books.google.com/books?id=zNo8AQAAIAAJ&pg=PA105|accessdate=29 July 2021|year=1857|publisher=T.

Adelaide had long entertained close relations with [[Cluny Abbey|Cluny]], then the center of the movement for ecclesiastical reform, and in particular with its abbots [[Majolus]] and [[Odilo of Cluny|Odilo]]. She retired to a nunnery she had founded in c.&nbsp;991 at [[Selz Abbey|Selz]] in [[Alsace]].<ref>"[http://saints.sqpn.com/saint-adelaide-of-burgundy Saint Adelaide of Burgundy]".

On her way to [[Burgundy]] to support her nephew [[Rudolph III of Burgundy|Rudolf III]] against a rebellion, she died at Selz Abbey on 16 December 999, days short of the millennium she thought would bring the [[Second Coming of Christ]]. She was buried in the Abbey and [[Pope Urban II]] canonized her in 1097.{{sfn|Wilson|2016|p=374}} After serious flooding, which almost completely destroyed it in 1307, Adelaide's relics were moved elsewhere. A goblet reputed to have belonged to Saint Adelaide has long been preserved in Seltz.; it was used to give potions to people with fever and the healings were said to have been numerous.

Adelaide constantly devoted herself to the service of the church and peace, and to the empire as guardian of both; she also interested herself in the conversion of the [[early Slavs|Slavs]]. She was thus a principal agent — almost an embodiment — of the work of the pre-[[East–West Schism|schism]] Church at the end of the [[Early Middle Ages]] in the construction of the religious culture of Central Europe.<ref>{{cite web|title=The Saints: A concise Biographical Dictionary|first=John|last=Coulson|publisher= Hawthorn Books, Inc.|year= 1960|url=http://www.ewtn.com/library/mary/adelaide.HTM}}</ref>
Some of her relics are preserved in a shrine in [[Hanover]]. Her feast day, 16 December, is still kept in many German dioceses.<ref name="Butler1956">{{cite book|author=Alban Butler|title=Butler's Lives of the Saints|url=https://books.google.com/books?id=-6Q5xTklH1cC|accessdate=29 July 2021|year=1956|publisher=P.
