The main idea is that Europeans began sustained, world-spanning exploration in the late medieval period and continued into the early modern era. Advances in navigation, ship design, and mapmaking—along with a strong drive for trade and wealth—made long ocean voyages possible. Pioneering routes around Africa to reach Asia, followed by voyages to the Americas and across the Pacific, led to a rapid expansion of geographic knowledge and global maps. This era of discovery culminated as European powers expanded their empires and continued mapping remote regions, shaping world history for centuries. The other timeframes don’t fit because they either precede this maritime outreach or come later, when exploration was driven more by imperial strategy and industrial-era power than the initial global reconnaissance.
