Explanation:

Italian Renaissance is a period covered in history between the 15th and 16th centuries accross Europe and making the transition from the middle ages to modernity. Renaissance is a French word that means"birth" and this defines the period as one of cultural revivals and renewed interest in appreciation of classical antiquity.
