As a nation state, Italy has emerged only in 1871. Until then the country was politically divided into a large number of independant cities, provinces and islands. The currently available evidences point out to a dominant Etruscan, Greek and Roman cultural influence on today's Italians.
In the "Pubblicazioni", the spouses declare that they want to get married; such declaration must be shown at the Town House and/or in the church, for some time (it varies depending on the historical period) to make sure that nobody has a real reason to prevent the marriage. The "Atto" is the document written at the moment of the marriage. The "allegati" are all the documents produced by the spouses for the marriage (birth certificates, claim of their being unmarried...).
