In order for the states to receive an amendment for consideration, 2/3rd majority of each House of Congress has to approve it.
Explanation:
Amendment to the constitution is only happened a few times in the history of the United States. In more than 200 years of history, the constitution has only been amended 33 times.
The first time Amendment was completed in December 15, 1791 and the latest one was completed in July 1, 1971.
The reason why there have been so few amendments is because 2/3rds of both houses of congress have to agree and vote in favor of these.
This is no easy task but this is precisely what makes the whole process worthwhile and keeps it in check.
The rulers of Italy before the Romans were the "Etruscans", although it should be noted that the Etruscan dominance of the region was not even close to the Romans' in terms of power and political nature.
