The "Helvetians":

 

Not many of the visitors to Rome, who pose for a photograph in front of the Swiss soldiers on guard at the gates of Vatican City, are familiar with the history of these troops who take an oath of loyalty to the Pope. To know more we must go back to the period of the Renaissance and discover the motives that in 1506 caused Pope Julius II to invite to Rome the Helvetian soldiers, renowned for their courage, noble sentiments and loyalty. Many centuries earlier the great Latin historian, Tacitus, had said: "The Helvetians are a people of warriors, famous for the valour of their soldiers." This is why the Swiss Cantons, as allies first with one side and then with another, played such an important role in the history of European politics. In fact as allies of Pope Julius II in 1512 they helped to shape Italy's destiny and were granted by the Pope the title of "Defenders of the Church's freedom". In those times, when to be a mercenary soldier was a commonplace occupation, there lived a people of warriors in the very heart of the Alps. The first Swiss Cantons had about 500,000 inhabitants and formed an overpopulated country, where, because of the precarious economic conditions of the times, there was much poverty. There was no choice but to emigrate and one of the most profitable jobs was that of a mercenary soldier abroad.

The Swiss Mercenaries:

There were some 15,000 men available for this type of work which was "organized" and controlled by the small Confederation of Cantons. The Confederation authorized the enlistment of the men and in return received corn, salt, or other commercial goods. The men themselves regarded this warring as a temporary period of summer emigration. They took part in brief but glorious wars and then returned home with the "pay" and the booty, to spend the winter. They were the best troops of those times.
