引言：海洋，人类历史的最后边疆 / Introduction: The Ocean, the Last Frontier of Human History

海洋，人类历史的最后边疆，在漫长的前现代时期始终笼罩在迷雾与想象之中。直到公元1405年，一支前所未有的舰队从中国太仓刘家港启航，驶向未知的地平线；几乎与此同时，在地球另一端的伊比利亚半岛，葡萄牙航海家们开始系统性地探索非洲西海岸。这两个相隔万里的进程，共同揭开了人类历史上第一次全球性海洋互联的序幕。然而，传统历史叙事长期将大航海时代简化为欧洲的“发现”与单向扩张，忽视了亚洲、非洲乃至美洲沿岸社会的主体性、能动性及其对全球互联的主动塑造。本书旨在打破陆地中心主义与欧洲中心论的双重桎梏，重新审视1405至1640年间，海洋如何成为多文明交汇、碰撞与融合的动态舞台。我们主张，大航海时代并非单一的欧洲崛起故事，而是一个由明朝郑和船队与伊比利亚探险家共同开启、众多力量参与的全球性多中心互动过程。本书将通过技术、贸易与文明三个维度，剖析这一转型期如何重塑世界格局，并为理解今日的全球化提供关键的历史纵深。

The ocean, the last frontier of human history, remained shrouded in mist and imagination for much of the pre-modern era. It was not until 1405 CE that an unprecedented fleet set sail from Liujia Port in Taicang, China, heading toward unknown horizons; almost simultaneously, on the Iberian Peninsula, Portuguese navigators began systematically exploring the West African coast. These two parallel processes, separated by thousands of miles, jointly unveiled the curtain on the first global oceanic interconnection in human history. Yet, traditional historical narratives have long reduced the Age of Exploration to a story of European "discovery" and unidirectional expansion, overlooking the agency, subjectivity, and active role of Asian, African, and even coastal American societies in shaping global connectivity. This book aims to break the dual shackles of land-centrism and Eurocentrism, re-examining how, between 1405 and 1640, the ocean became a dynamic stage for multi-civilizational encounter, collision, and fusion. We argue that the Age of Exploration was not a singular tale of European ascendancy, but a global, multi-centric interactive process initiated jointly by Ming China's Zheng He fleets and Iberian explorers, involving numerous other actors. Through the lenses of technology, trade, and civilization, this book will analyze how this transformative period reshaped the world order and provides essential historical depth for understanding today's globalization.

海洋：被忽视的历史维度与陆地中心主义的局限

传统历史书写长期将陆地视为文明发展的唯一舞台，海洋则被边缘化为分隔大陆的“空白空间”或仅作为海上通道的附属物。这种陆地中心主义（land-centrism）根植于农耕文明对土地资源的依赖，以及近代民族国家史学对领土边界的强调。例如，经典的历史分期如“古典时代”“中世纪”均以欧亚大陆的帝国兴衰为轴心，海洋事件仅作为点缀。即便是研究古代贸易的学者，也常聚焦于丝绸之路等陆路网络，而将印度洋、地中海的海上贸易视为陆路的补充。这种视角严重低估了海洋在物种传播（如作物、牲畜、病原体）、技术扩散（如造船、导航）、文化交融（如宗教、语言）乃至政治实体形成（如威尼斯、马六甲、基尔瓦）中的核心作用。

海洋并非“空白”，而是一个充满复杂性的三维空间：它是交通网络、经济地带、生态界面，更是军事战场与想象领域。历史学家费尔南·布罗代尔在其巨著《15至18世纪的物质文明、资本主义和世界经济》中，已敏锐指出长时段（longue durée）结构下，地中海作为一个“整体”如何塑造了区域历史。然而，这种海洋视野多局限于区域研究，未能充分整合全球尺度。更重要的是，前现代时期的海洋互联并非始于欧洲。在1405年之前，印度洋已存在一个由阿拉伯、印度、中国、东南亚商人共同维护的跨国贸易网络，其范围从东非到东南亚，再连接至中国南海。这个网络基于季风规律、信用体系（如“哈瓦拉”）、多语言社区（如阿拉伯语、泰米尔语、中文的混合使用）和灵活的政权关系（如与地方苏丹国的合作）。它虽未实现跨洋直达，却已构建了深度的经济文化整合。郑和船队的首次远航，正是深入并暂时强化了这一既有网络，而非从零开始“开辟”新航路。同样，伊比利亚航海家绕过好望角后，立即遭遇并试图掌控这个成熟的印度洋体系。因此，大航海时代的本质，是全球各大洋——印度洋、大西洋、太平洋——从区域性的互动圈，逐步被强行或有机地连接成一个更紧密整体的过程，而这一过程的起点正是1405年郑和船队对印度洋的深度介入与伊比利亚对非洲海岸的系统探索。

The historical dimension of the ocean has long been neglected, with land-centrism dominating narratives. This perspective, rooted in agrarian societies' dependence on terrestrial resources and modern national historiography's focus on territorial boundaries, treats oceans as mere "blank spaces" or secondary routes. Classic periodizations like "Classical Antiquity" or "the Middle Ages" revolve around Eurasian empires, with maritime events as footnotes. Even trade studies often prioritize overland routes like the Silk Road, viewing Indian Ocean or Mediterranean commerce as supplementary. This view severely underestimates the ocean's role in species diffusion (crops, livestock, pathogens), technological spread (shipbuilding, navigation), cultural fusion (religions, languages), and political entity formation (Venice, Malacca, Kilwa).

The ocean was not a "blank" but a complex three-dimensional space: a transportation network, an economic zone, an ecological interface, a military battlefield, and a realm of imagination. Historian Fernand Braudel, in *The Mediterranean and the Mediterranean World in the Age of Philip II*, insightfully showed how the Mediterranean functioned as a "whole" shaping regional history under long-term structures. However, this maritime vision remained regional and failed to integrate global scales. Crucially, pre-modern oceanic connectivity did not originate in Europe. Before 1405, the Indian Ocean already hosted a transnational trade network jointly maintained by Arab, Indian, Chinese, and Southeast Asian merchants, spanning from East Africa to Southeast Asia and connecting to the South China Sea. This network operated on monsoon patterns, credit systems (like *hawala*), multilingual communities (Arabic, Tamil, Chinese), and flexible political relations (cooperation with local sultanates). While not transoceanic, it achieved deep economic and cultural integration. Zheng He's first voyage penetrated and temporarily reinforced this existing network, rather than "opening" new routes from scratch. Similarly, Iberian navigators, upon rounding the Cape of Good Hope, immediately encountered and sought to dominate this mature Indian Ocean system. Thus, the essence of the Age of Exploration lies in the process by which the world's major oceans—the Indian, Atlantic, and Pacific—gradually transitioned from regional interaction spheres to a more tightly integrated whole, a process whose starting point is marked by Zheng He's deep engagement with the Indian Ocean and Iberia's systematic exploration of the African coast in 1405.

时间框架的界定：为何是1405-1640？

界定大航海时代的时间跨度需要同时考虑东方与西方的关键转折点。1405年并非偶然，而是明朝永乐皇帝派遣郑和率领庞大舰队首次远航的年份。郑和船队规模空前，据《明史》记载，首次下西洋即有船只200余艘、人员27,000余名，访问了从东南亚至东非的30多个国家和地区。这一事件标志着国家力量主导的、以政治宣威与朝贡体系扩展为目标的远洋活动达到高峰。在西方，1415年葡萄牙占领北非休达（Ceuta）常被视为伊比利亚海外扩张的起点，但1415年之前葡萄牙已开始探索马德拉群岛（1419年发现），而1405年与郑和首航几乎同时，象征了两大海洋力量的并行崛起。因此，1405年作为一个对称的起点，更能体现全球多中心启动的特征。

1640年作为终点同样具有东西方双重意义。在西方，1640年葡萄牙爆发复国运动，摆脱西班牙统治，结束了长达60年的伊比利亚联盟（1580-1640）。这一事件标志着葡萄牙帝国进入新阶段，其扩张动力从王室垄断转向更依赖私人商业资本，同时西班牙的霸权也开始相对衰落。在东方，1644年明朝灭亡、清朝建立，但1640年已可见端倪：明朝在郑和之后逐步收缩海洋政策，隆庆开关（1567年）仅限有限私人贸易，而清初更严厉的海禁（如1661年“迁海令”）预示了东亚海洋力量的系统性退潮。以1640年为终点，恰好捕捉了伊比利亚扩张的转折与东亚海洋退缩的临界点，完成了从多中心互动向欧洲相对主导的过渡。此外，从技术史角度看，1640年前后，欧洲的航海技术（如更精确的经度测量尝试、更高效的舰船设计）开始形成代差优势，而郑和船队所代表的巨型宝船技术并未持续发展。因此，1405-1640年框定了一个全球海洋力量相对均衡、多文明深度互动的独特时代，之后欧洲的压倒性优势才逐渐显现。

The temporal framing of the Age of Exploration requires identifying pivotal turning points from both Eastern and Western perspectives. 1405 is not arbitrary; it marks the year when the Ming Yongle Emperor dispatched Zheng He with a massive fleet on its first voyage. According to the *Ming History*, the first voyage included over 200 ships and more than 27,000 personnel, visiting over 30 countries and regions from Southeast Asia to East Africa. This event signifies the peak of state-led, politically motivated oceanic expeditions aimed at extending the tributary system. In the West, Portugal's capture of Ceuta in North Africa in 1415 is often cited as the start of Iberian expansion, but Portuguese exploration of Madeira (discovered in 1419) began earlier. The simultaneity of Zheng He's first voyage and early Iberian explorations around 1405 symbolizes the parallel rise of two major maritime powers. Thus, 1405 serves as a symmetrical starting point, reflecting a globally multi-centric launch.

1640 as an endpoint carries dual significance. In the West, 1640 marks the Portuguese Restoration War, ending the Iberian Union (1580-1640) and ushering in a new phase for the Portuguese Empire, shifting from royal monopoly to greater reliance on private commercial capital, while Spanish hegemony also began to wane. In the East, although the Ming fell in 1644, the retreat was already evident by 1640: after Zheng He, Ming maritime policy gradually contracted; the limited private trade opened under the Longqing Emperor (1567) was restricted, and the early Qing's stricter sea bans (like the 1661 "Great Clearance") foreshadowed a systematic withdrawal of East Asian maritime power. Thus, 1640 captures the turning point of Iberian expansion and the临界点 of East Asian maritime retreat, completing the transition from multi-centric interaction to relative European dominance.
