Explain how culture/religion/and or previous periods influenced the italian renaissance?

The Italian Renaissance was a time of cultural differentiation...

With different types of cultures (which ties in religion) affecting the life of those who were Italian (or part-took in said Italian ventures), the Italian race or you could say, power prevailed greatly.  With more cultures clashing against one another during the Italian Renaissance there was, of course, a lot of wars or hostile behaviour against one another.

Later down the road, this lead to many accomplishments during the Italian Renaissance such as technology levels increasing and the race of all Italians began to spread worldwide.

^^ This is just a general understanding, if you dig deeper into the Italian Renaissance under the history website, you'll learn more about the renaissance and even understand why this was such a remarkable one.
