Globalization (or globalisation) refers to the process or processes of international integration. Human Interaction over long distances, such as the overland Silk Road that connected Asia, Africa and Europe, existed thousands of years ago. In the 15th century, Europeans made important advances in exploring the World Ocean and locating the "New World" of the Americas. Global movement of people, goods, and ideas expanded significantly in the early 19th century with development of new forms of transportation and telecommunications that seem to "compress" time and space. In the 20th century, road vehicles and airlines made transportation much faster.
