Also, the majority of what we call "Italian Renaissance" is actually within the medieval era (for example Dante Alighieri, Boccacio and Brunelleschi were 14th century).
One could argue that the boundaries between the medieval and early modern in historiography are often very murky (and you could even argue the same with the one between early modern and industrial). For many scholars of the early modern period, the Italian Renaissance is still considered a break from the medieval, and therefore belongs to the early modern period, because you have the birth of intellectual and artistic traditions that continue on past the supposed time period when the Italian Renaissance occurred, and into when we would strictly define as early modern.
There's no strict beginning and end to the early modern period; periodization is a very arbitrary concept.
