The Italian Renaissance was a time of cultural differentiation;
With various types of cultures - which had distinct religions - changing the life of those who were Italian, the Italian race or you could say, power prevailed greatly. With more cultures colliding towards one another during the Italian Renaissance, there was, of course, a lot of wars or hostile behaviour against one another.
In the future, this lead to many successes during the Italian Renaissance such as technology levels rising and the race of all Italians began to expand worldwide.
