The Age of Exploration大航海时代

In the 15th century, Portuguese and Spanish sailors began pushing beyond the limits of the known world, driven by the search for direct sea routes to the spices and riches of Asia, by religious zeal, and by advances in ships, navigation, and cartography. Portugal, under the patronage of figures like Prince Henry, worked its way down the coast of Africa, and in 1498 Vasco da Gama reached India by sailing around its southern tip.15世纪，葡萄牙与西班牙的水手开始突破已知世界的边界。驱动他们的，是寻找直通亚洲香料与财富的海上航线、宗教热忱，以及船舶、航海与制图技术的进步。在恩里克王子等人的赞助下，葡萄牙人沿非洲海岸一路南下，1498年，达·伽马绕过非洲南端抵达印度。

In 1492, sailing west for Spain in search of Asia, Christopher Columbus instead reached islands in the Caribbean. He had not found a new route to the East but had opened sustained contact between the Old World and the Americas — continents that had developed in near-total isolation from one another for thousands of years. In 1519–1522 an expedition begun by Ferdinand Magellan completed the first circumnavigation of the globe.1492年，哥伦布为西班牙向西航行以寻找亚洲，却抵达了加勒比海的岛屿。他并未找到通往东方的新航路，却开启了旧大陆与美洲之间持续的接触——这两片大陆此前数千年间几乎彼此隔绝、各自发展。1519至1522年，由麦哲伦发起的探险队完成了人类首次环球航行。

The consequences were world-changing. The 'Columbian Exchange' moved crops, animals, people, and pathogens across the Atlantic in both directions: maize, potatoes, tomatoes, and cacao spread to the Old World, while wheat, horses, cattle, and sugar came to the Americas. This exchange transformed diets and populations across the globe — but it also carried Old World diseases such as smallpox to the Americas.其后果改变了世界。「哥伦布大交换」使作物、动物、人口与病原体在大西洋两岸双向流动：玉米、马铃薯、番茄与可可传入旧大陆，而小麦、马、牛与甘蔗则来到美洲。这场交换改变了全球的饮食结构与人口分布——但它也把天花等旧大陆的疾病带到了美洲。

For the Indigenous peoples of the Americas, contact was catastrophic. Old World epidemics, against which they had no immunity, killed a large share of the population within a century — a demographic collapse that, together with conquest by the Spanish and Portuguese, shattered civilizations such as the Aztec and Inca empires and enabled the seizure of vast territories.对美洲原住民而言，这场接触是灾难性的。他们对旧大陆的传染病毫无免疫力，在一个世纪之内，大批人口因疫病死亡——这场人口崩溃，加上西班牙与葡萄牙的征服，摧毁了阿兹特克与印加等文明，并使殖民者得以攫取广袤的领土。

The age also gave rise to the transatlantic slave trade, which forcibly transported millions of enslaved Africans to labour in the mines and plantations of the Americas — one of history's greatest crimes and forced migrations. Out of these voyages emerged the first truly global economy and the great European maritime empires, binding four continents into networks of trade, wealth, and exploitation whose consequences still shape the modern world.这个时代也催生了跨大西洋奴隶贸易，数以百万计的非洲人被强行贩运至美洲，在矿场与种植园中做苦工——这是历史上最深重的罪行与被迫迁徙之一。正是从这些航行中，诞生了人类第一个真正意义上的全球经济，以及欧洲各大海上帝国，把四大洲编织进贸易、财富与剥削的网络，其后果至今仍塑造着现代世界。
