Why would the Renaissance have started in Italy? I would say this is because of something of an error – the Renaissance began as education, art, record keeping, trade and invention started influencing life. We often think about it starting in Italy because both Vatican and Rome provided artisans and thinkers a ready focus of support as well as commercial hubs such as Venice. International trade throughout Venice, for instance the spice trade, made the city a focal point for both the Middle East and Europe.
Several claims exist that most of the important records were preserved by monks in places such as Ireland and aided the resurrection of civilization during the rebirth so a lot of the picture is left blank when one says it began in Italy.
