The First Global Age, or the Age of Exploration, is the common name for the period of time between the late 1400s to the early 1800s, with the advent of the Second Global Age, or the Age of Imperialism.
There were many explorers before the Age of Exploration (such as Alexander the Great), and many afterwards (including Neil Armstrong). However, the core of the explorers was during the late 1400s/early 1500s. Some explorers are given at: List of explorers.
