[[Internal migration in Italy]] is a [[human migration]] within the [[Italian geographical region]] that occurred for similar reasons to [[Italian diaspora|emigration]], primarily socioeconomic.<ref name="salogentis">{{cite web|url=http://www.salogentis.it/2012/11/16/lemigrazione-interna-italiana-negli-anni-50-e-60/|title=L'emigrazione interna italiana negli anni '50 e '60|date=16 November 2012 |accessdate=8 February 2018|language=it}}</ref> Its largest wave consisted of 4 million people moving from [[Southern Italy]] to [[Northern Italy]] (and mostly to Northern or Central Italian industrial cities like Rome or Milan, etc.), between the 1950s and 1970s.<ref name="uniud">{{cite web|url=https://www.uniud.it/it/ateneo-uniud/ateneo-uniud-organizzazione/dipartimenti/dies/ricerca/allegati_wp/wp_2013/wp04_2013.pdf|title=Una indagine CATI per lo studio della mobilità interna in Italia in un'ottica longitudinale|accessdate=8 February 2018|language=it|archivedate=20 April 2021|archiveurl=https://web.archive.org/web/20210420020548/https://www.uniud.it/it/ateneo-uniud/ateneo-uniud-organizzazione/dipartimenti/dies/ricerca/allegati_wp/wp_2013/wp04_2013.pdf|url-status=dead}}</ref>

The oldest migration goes back to the 11th century when soldiers and settlers from [[Northern Italy]] (at the time collectively called "Lombardy"<ref>{{Cite web|url=http://www.treccani.it/vocabolario/lombardo/|title=Lombardo|accessdate=15 April 2022|work=treccani.it|language=it}}</ref>), settled the central and eastern part of [[Sicily]] during the [[Norman conquest of southern Italy]]. After the marriage between the Norman king [[Roger I of Sicily]] with [[Adelaide del Vasto]], member of [[Aleramici]] family, many Lombard colonisers left their homeland, in the Aleramici's possessions in [[Piedmont]] and [[Liguria]], to settle on the island of Sicily.<ref>{{Cite book|url=https://books.google.com/books?id=1IBspuVRwnUC&pg=PA323|title=The Society of Norman Italy|author1=Graham A.
