How interconnected was the world before the age of exploration?

The era known as the Age of Exploration, sometimes called the Age of Discovery, officially began in the early 15th century and lasted through the 17th century. The period is characterized as a time when Europeans began exploring the world by sea in search of new trading routes, wealth, and knowledge. The impact of the Age of Exploration would permanently alter the world and transform geography into the modern science it is today.
