秀吉は、宣教師の背後に世界帝国を見た
大河ドラマ豊臣兄弟は今週はお休みのようですが、どのように描かれようと、豊臣秀吉は日本史では突出したスターの一人ですよね。
豊臣秀吉は、織田信長のキリスト教布教政策から、なぜ突然、キリスト教の宣教師を日本から追放しようとしたのでしょうか。
学校では、「キリスト教の勢力拡大を恐れたから」と簡単に習います。しかし、当時の世界地図を広げてみると、別の景色が見えてきます。
16世紀のスペインとポルトガルは、単に外国へ船を出して商売をしていたわけではありませんでした。
宣教師が現地に入り、領主や住民を改宗させる。商人が港を開き、交易網をつくる。
そして必要になれば、軍隊と植民地官僚が進出する。
もちろん、すべての地域で、
「宣教師、商人、軍隊」
という順序が機械的に繰り返されたわけではありません。
軍隊と宣教師が同時に進出した地域もあり、軍事征服の後から宣教師が入った地域もあります。
しかし、布教、交易、軍事、統治が別々の活動ではなく、帝国拡大の一つのシステムとして結びついていたことは間違いありません。
秀吉は、九州でその入口を見たのではないでしょうか。
キリシタン大名が改宗する。
領民にも改宗が広がる。
寺社が破壊される。
外国の宗教組織に港や土地が寄進される。
ポルトガル船が出入りし、日本人が商品として海外へ運び出されていく。
大村純忠は長崎と茂木をイエズス会に寄進しました。
外国人宣教師が日本の港湾都市に強い影響力を持ち、キリシタン大名がその国際的な宗教ネットワークと直接結びついていく。
天下統一を進めていた秀吉から見れば、これは単なる信仰の問題ではありません。
「この土地と、ここに住む人々を、最終的に誰が支配するのか」
という国家主権の問題だったのです。
秀吉が見た、日本人奴隷の現実
秀吉が九州で知ったもう一つの現実が、日本人奴隷の海外流出でした。
戦乱や貧困の中で売られた日本人の男女や子供たちが、ポルトガル系商人の交易網を通じ、マカオ、ゴア、マラッカ、フィリピンなどへ運ばれていました。
さらに遠く、ヨーロッパ方面に渡った日本人も確認されています。
1587年、秀吉はイエズス会の責任者ガスパール・コエリョを問いただし、日本人の売買をやめさせ、すでに海外へ売られた者を帰国させるよう要求しました。
日本人奴隷の正確な総数は分かっていません。
当時の完全な名簿や輸出統計が残っているわけではなく、「5万人」という数字も確定したものではありません。
しかし、相当数の日本人が海外へ売られ、数万人規模だったとする推計が存在することは確かです。
秀吉の命令だけで、すべての人身売買が直ちに消えたわけでもありません。
それでも、天下人が日本人の海外売買を国家の問題として取り上げ、外国商人と宣教師に停止を要求した意味は大きかったと思います。
1587年のキリスト教関連の命令には、日本人の海外売買への強い懸念が背景の一つとして存在しました。
秀吉を、近代的な人権思想を持つ奴隷解放者として描くべきではないでしょう。
彼自身、その後の朝鮮出兵で起きた人々の連行を止められませんでした。
秀吉が守ろうとしたのは、普遍的な人権というよりも、自らの支配下にある人口、労働力、領土、そして統治権だったと考える方が自然です。
しかし、結果として彼の命令が、日本人の海外流出に強い歯止めをかけたことも否定できません。
秀吉はキリスト教を嫌ったから排除したのではない。
信仰の背後に、交易があり、交易の背後に軍事力があり、そのさらに背後に世界帝国が存在することに気づいたのです。
「大航海時代」という美しい言葉
私たちは、コロンブスやマゼランの時代を「大航海時代」と呼びます。
どこかロマンがあります。
帆船が未知の海へ出て、新しい大陸を発見し、世界を一つに結んだ時代。
しかし、発見された側から見れば、それは「大侵略時代」でもありました。
スペインとポルトガルの海洋進出によって、ヨーロッパ、アフリカ、アメリカ、アジアは初めて恒常的な一つの交易圏になります。
銀、香辛料、生糸、武器、宗教、言語、病原体。
そして奴隷。
あらゆるものが、海を渡りました。
世界がつながることは、必ずしも世界が平和になることを意味しません。
富と知識が移動する道は、そのまま軍隊と感染症と収奪が移動する道にもなるのです。
世界史を動かした九つの波
こうして考えてみると、世界史が大きく動く瞬間には、共通する原理があります。
それは、強大な王が登場したときだけではありません。
人、物、情報、宗教、技術が移動する速度と範囲が、突然拡大したときです。
①第一の波 アレクサンドロス大王の東征
紀元前4世紀、マケドニアのアレクサンドロス大王は、ギリシャからエジプト、ペルシアを越え、インド西北部まで進みました。
この遠征によってギリシャ文化とオリエント文化が混ざり合い、ヘレニズム世界が生まれます。
ガンダーラ仏の顔がギリシャ彫刻に似ているのも、遠く離れた文明が接触した痕跡です。
軍隊が通った道を、芸術と医学と哲学が後から歩いたのです。
②第二の波 ローマ帝国と漢帝国
紀元前後、西にはローマ帝国、東には漢帝国という二つの巨大文明圏が成立しました。
両帝国が直接向かい合ったわけではありません。しかし、その間を中央アジアの商人が往来し、絹、ガラス、香辛料、金銀が移動しました。
シルクロードは一本の道路ではありません。
無数の都市と商人と隊商をつないだ、古代のネットワークでした。
③第三の波 イスラム帝国の拡大
7世紀以降、イスラム勢力はアラビア半島から中東、北アフリカ、中央アジアへ広がりました。
イスラム文明は、征服した土地の文化を単に消し去ったのではありません。
ギリシャ哲学、ペルシアの行政、インド数学、中国の製紙技術を集め、アラビア語へ翻訳し、再編集しました。
そして、その知識を再び東西へ配った。
イスラム世界は、古代文明の巨大な知識編集装置だったのです。
④第四の波 モンゴル帝国
13世紀、モンゴル帝国は中国から中央アジア、ロシア、中東までを結びました。
馬と駅伝制によって、大陸の距離が一気に縮まりました。
商人、外交官、宗教者、医師、天文学者、職人が移動し、火薬、印刷、医学、天文学が広がっていきます。
一方で、交易路を通って病原体も運ばれました。
世界がつながると、知識も災厄も速くなる。
現代の航空網と感染症の関係を見れば、これは決して昔話ではありません。
⑤第五の波 スペイン・ポルトガルの海洋進出
15世紀から16世紀にかけて、世界の中心線は陸から海へ移りました。
ポルトガルはアフリカを回ってインド洋へ入り、スペインは大西洋を越えてアメリカ大陸へ進出しました。
さらにマニラを介して、アメリカ大陸の銀と中国の商品が太平洋を越えて結ばれます。
秀吉が直面したのは、この第五の波でした。
日本の地方大名が、自分よりもはるかに大きな世界システムと直接つながり始めている。
その危険性を、おそらく秀吉は直感的に理解したのでしょう。
⑥第六の波 オランダ・イギリスの商業帝国
17世紀になると、世界支配の方法が変わります。
国王の軍隊だけではなく、東インド会社のような企業が、軍隊を持ち、要塞を造り、条約を結び、貨幣を発行するようになりました。
会社、金融、海運、軍事が一体化したのです。
スペインの帝国が王と宗教によって広がったのだとすれば、オランダとイギリスの帝国は、株式会社と金融によって広がりました。
現代の資本主義の原型が、ここにあります。
⑦第七の波 産業革命と大英帝国
18世紀末以降、蒸気機関、鉄道、工場、大量生産が世界の力関係を変えました。
それまでの帝国にも、兵士と船はありました。
しかし、蒸気船と鉄道と電信を持つ帝国は、兵士と物資と命令を、桁違いの速さで移動させることができました。
西洋が世界を支配した最大の理由は、人種や宗教の優越ではありません。
石炭のエネルギーを機械に変える技術を、先に獲得したからです。
⑧第八の波 二度の世界大戦とアメリカの世紀
二度の世界大戦によって、ヨーロッパ中心の世界は終わりました。
代わって登場したのが、アメリカとソ連です。
とりわけアメリカは、領土を直接植民地化するだけではなく、ドル、国際金融、軍事同盟、英語、映画、音楽、科学技術によって世界を組織しました。
それは、土地を所有する帝国ではなく、世界のルールとネットワークを握る帝国でした。
⑨第九の波 AI・デジタル時代
そして現在、私たちは第九の波の中にいます。
かつて国家の力を決めたのは、馬、帆船、火薬、蒸気機関、石油、核兵器でした。
これから国家の力を決めるのは、半導体、データ、電力、通信網、そしてAIになるでしょう。
モンゴル帝国は陸路を支配しました。
スペインとポルトガルは海路を支配しました。
イギリスは工場と海運を支配しました。
アメリカは金融と情報を支配しました。
次の覇権を握るのは、知能を大量に生産し、配り、管理する仕組みを支配した国なのかもしれません。
歴史とは、英雄や悪人だけが動かすものではありません。
道ができる。
船が速くなる。
情報が広がる。
資本が集まる。
新しい武器が生まれる。
すると、それまで遠く離れていた世界が突然接触し、古い秩序が崩れます。
世界史は、移動の速度が突然上がったときに大きく動く。
そして現在、AIによって急激に速くなろうとしているのは、物の移動でも、人の移動でもありません。
人間が考え、判断し、知識を生み出す速度そのものなのです。
Hideyoshi Saw an Empire Behind the Missionaries
The historical drama The Toyotomi Brothers may be taking a break this week, but regardless of how any television adaptation portrays him, Toyotomi Hideyoshi remains one of the most extraordinary figures in Japanese history.
One question has continued to fascinate historians:
Why did Hideyoshi, who initially tolerated Christianity under the influence of Oda Nobunaga’s policies, suddenly move toward expelling Christian missionaries from Japan?
In school textbooks, the explanation is often simplified:
“Because he feared the growing influence of Christianity.”
But when we place Hideyoshi’s decision within the context of the 16th-century world, a very different picture emerges.
At that time, Spain and Portugal were not simply sending ships overseas in search of trade opportunities.
Their global expansion involved a much broader system.
Missionaries entered foreign lands and converted local rulers and populations.
Merchants opened ports and established trading networks.
And when necessary, military forces and colonial administrators followed.
Of course, history was never as simple as a fixed sequence of:
missionaries → merchants → armies
In some regions, military conquest came first. In others, religious and commercial expansion occurred simultaneously.
However, there is little doubt that evangelization, trade, military power, and political control were deeply interconnected components of European imperial expansion.
And Hideyoshi may have seen the beginning of that process unfolding in Kyushu.
Christian feudal lords were converting.
Their subjects were increasingly encouraged to follow.
Temples and shrines were sometimes damaged.
Land and ports were donated to foreign religious organizations.
Portuguese ships arrived regularly, while Japanese people were being transported overseas as part of expanding commercial networks.
The Christian daimyo Otomo Sorin and Omura Sumitada are often discussed in this context. In particular, Omura Sumitada granted Nagasaki and Mogi to the Jesuits, creating an unusual situation in which a foreign religious organization gained influence over important Japanese ports.
For Hideyoshi, who was in the process of unifying Japan, this was not merely a question of religious belief.
The deeper question was:
Who ultimately controls this land and the people who live on it?
It was a question of sovereignty.
The Reality of Japanese Slavery Hideyoshi Encountered
Another reality that Hideyoshi confronted in Kyushu was the overseas sale of Japanese people.
During an era of warfare and poverty, Japanese men, women, and children were sold and transported through Portuguese-linked trading networks to places such as Macau, Goa, Malacca, and the Philippines.
Some even reached Europe.
In 1587, Hideyoshi confronted Gaspar Coelho, the Jesuit superior in Japan, demanding that the sale of Japanese people be stopped and that those already taken overseas be returned.
The exact number of Japanese people who were sold abroad remains uncertain.
No complete records of these transactions survive, and figures such as “50,000 people” cannot be confirmed with certainty.
However, historians agree that the scale was significant, and that a considerable number of Japanese people were transported overseas through these networks.
Hideyoshi’s orders did not immediately eliminate all forms of human trafficking.
Nor should Hideyoshi be portrayed as a modern abolitionist motivated by universal human rights.
His later invasion of Korea itself resulted in the forced removal of many people.
The values he sought to protect were not identical to modern concepts of individual rights. They were more closely connected to sovereignty over population, labor, territory, and political authority under his rule.
Yet one fact remains important:
Hideyoshi, as Japan’s ruler, recognized the overseas sale of Japanese people as a national issue and attempted to intervene.
His 1587 restrictions on Christianity were shaped not only by concerns about religion, but also by fears surrounding foreign influence, trade networks, and the movement of Japanese people beyond his control.
Hideyoshi Did Not Reject Christianity Simply Because It Was Christianity
To understand Hideyoshi’s decision, it is necessary to move beyond the simple explanation that “he hated Christianity.”
That interpretation misses the larger picture.
Hideyoshi saw a connection.
Behind religion was trade.
Behind trade was military power.
And behind that military power was the possibility of a global empire expanding across oceans.
What concerned him was not faith alone.
It was the arrival of a new world order.
In the 16th century, Japan was no longer isolated from global history.
The oceans had become highways connecting distant civilizations.
And Hideyoshi, standing at the edge of this new era, recognized that Japan was not merely encountering a foreign religion.
It was encountering globalization itself.
The Age of Exploration Was Also an Age of Conquest
We often refer to the era of Columbus and Magellan as the Age of Exploration.
The phrase evokes images of courage and adventure—wooden ships crossing unknown oceans, new continents appearing on the horizon, and the gradual emergence of a connected world.
From the perspective of those who set sail, it was an age of discovery.
From the perspective of those who were discovered, however, it was often an age of conquest.
European expansion did far more than redraw maps.
It created, for the first time in history, a truly global network linking Europe, Africa, Asia, and the Americas through continuous trade and communication.
Silver crossed the Pacific.
Spices crossed the Indian Ocean.
Silk moved westward.
Firearms, languages, religions, crops, and technologies circulated on an unprecedented scale.
So did diseases.
So did slavery.
Globalization has never been simply the movement of wealth and knowledge.
The same routes that carry commerce also carry armies, epidemics, and systems of exploitation.
The sixteenth century reminds us of a lesson that remains true today:
Connection creates opportunity—but it also creates vulnerability.
Nine Waves That Reshaped World History
Looking across the broader sweep of history, a striking pattern emerges.
Civilizations are transformed not only by the rise of extraordinary rulers.
More often, they are transformed when the speed and scale at which people, goods, ideas, technologies, and beliefs move suddenly increase.
History advances in waves of connectivity.
Each wave expands the reach of human interaction, creating new opportunities while simultaneously dismantling old political and cultural boundaries.
The First Wave: Alexander the Great
In the fourth century BCE, Alexander of Macedon marched from Greece through Egypt and Persia before reaching northwestern India.
His conquests did more than create a vast empire.
They connected civilizations that had previously developed largely in isolation.
Greek philosophy encountered Persian administration.
Egyptian science met Hellenic art.
The result was the Hellenistic world—a fusion rather than a replacement of cultures.
The famous Buddhist sculptures of Gandhara, whose faces bear unmistakable Greek artistic influence, remain visible evidence of that encounter.
The armies arrived first.
Art, medicine, philosophy, and scholarship followed.
The Second Wave: Rome and Han China
Around the beginning of the Common Era, two great centers of civilization emerged at opposite ends of Eurasia.
To the west stood the Roman Empire.
To the east, the Han dynasty.
Although the two empires never confronted one another directly, merchants traveling across Central Asia connected them through an intricate web of exchange.
Silk moved westward.
Glass, precious metals, spices, and ideas moved eastward.
The Silk Road was never a single road.
It was an interconnected network of cities, caravans, oasis kingdoms, and trading communities that linked distant worlds long before globalization became a modern concept.
The Third Wave: The Islamic World
Beginning in the seventh century, Islamic civilization expanded rapidly across the Middle East, North Africa, Central Asia, and beyond.
Its significance extended far beyond military conquest.
The Islamic world became one of history’s greatest centers for collecting, translating, and refining knowledge.
Greek philosophy.
Persian administration.
Indian mathematics.
Chinese papermaking.
Rather than eliminating earlier civilizations, Islamic scholars absorbed their achievements, translated them into Arabic, expanded upon them, and transmitted them across continents.
In many respects, the medieval Islamic world functioned as humanity’s first great knowledge network.
The Fourth Wave: The Mongol Empire
The Mongol Empire of the thirteenth century united an enormous portion of Eurasia under a single political framework.
For the first time, merchants, diplomats, physicians, astronomers, craftsmen, and religious figures could travel across much of the continent with unprecedented speed and security.
Technologies such as gunpowder, printing, medicine, and astronomy spread more rapidly than ever before.
Yet knowledge was not the only traveler.
The same trade routes also carried infectious diseases.
The Black Death demonstrated a recurring truth of history:
The more connected the world becomes, the faster both innovation and catastrophe can spread.
It is a lesson that feels strikingly familiar in an age of international air travel and global pandemics.
The Fifth Wave: The Maritime Empires of Spain and Portugal
During the fifteenth and sixteenth centuries, the center of global power shifted from land to sea.
Portugal rounded Africa and entered the Indian Ocean.
Spain crossed the Atlantic and established its presence in the Americas.
Soon afterward, the Manila Galleon connected American silver with Chinese goods across the Pacific, completing the first truly global commercial network.
It was within this fifth wave that Hideyoshi found himself.
For centuries, Japan’s regional lords had competed primarily within the boundaries of the Japanese archipelago.
Suddenly, some of them were becoming directly connected to international religious institutions, overseas merchants, and global trading systems that extended far beyond Japan’s political horizon.
Hideyoshi may not have understood every detail of European geopolitics.
He did not need to.
He recognized something more fundamental.
Japan was no longer interacting simply with foreign visitors.
It was becoming part of a rapidly expanding global system whose scale exceeded anything previous generations had experienced.
That realization helps explain why Hideyoshi’s policies toward Christianity cannot be understood solely as questions of religion.
They were also responses to the first great wave of globalization.
The fifth wave of globalization did not mark the end of history.
It merely opened the door to a succession of even more profound transformations.
Each new era was driven by a different technology, a different network, and a different way of organizing power.
The Sixth Wave: The Commercial Empires of the Dutch and the British
By the seventeenth century, the nature of empire itself had begun to change.
Power no longer rested solely with kings and their armies.
Chartered companies such as the Dutch East India Company and the English East India Company acquired extraordinary authority. They maintained private armies, built fortified ports, negotiated treaties, minted currency, and governed distant territories.
Commerce, finance, naval power, and political authority became inseparable.
If the Spanish and Portuguese empires had expanded through the combined influence of monarchy and religion, the Dutch and British built global empires through corporations, capital markets, and maritime commerce.
In many respects, they created the blueprint for modern capitalism.
The Seventh Wave: The Industrial Revolution
The Industrial Revolution transformed the foundations of global power.
Empires had always possessed soldiers and ships.
What they had never possessed before were steam engines, railways, factories, and telegraphs.
For the first time, armies, supplies, information, and political decisions could move at speeds unimaginable to earlier generations.
The balance of power shifted accordingly.
The West did not dominate the nineteenth century because of racial or religious superiority.
It prevailed because it mastered the ability to convert coal into mechanical energy—and mechanical energy into economic and military power.
Technology, more than ideology, became the decisive force of history.
The Eighth Wave: The American Century
The two World Wars brought an end to centuries of European global dominance.
A new international order emerged, led primarily by the United States and, for several decades, the Soviet Union.
The United States, however, exercised influence in a way unlike previous empires.
Its power rested not simply on territorial control but on systems.
The dollar became the world’s reserve currency.
International financial institutions shaped global commerce.
Military alliances extended security across continents.
English became the language of science, business, and diplomacy.
Hollywood, popular music, universities, technological innovation, and the internet projected American influence far beyond its borders.
This was no longer an empire built on colonies alone.
It was an empire sustained by networks, standards, and institutions.
Ownership of territory mattered less than ownership of the rules by which the world operated.
The Ninth Wave: Artificial Intelligence
Today, we are entering a ninth great wave of history.
Throughout the past two thousand years, different technologies have defined national power.
Horses.
Sailing ships.
Gunpowder.
Steam engines.
Oil.
Nuclear weapons.
Each transformed the way civilizations expanded, competed, and governed.
The technologies shaping the twenty-first century are different.
Semiconductors.
Data.
Electricity.
Communication networks.
And above all, artificial intelligence.
The Mongols controlled the great land routes.
Spain and Portugal mastered the oceans.
Britain dominated industrial production and maritime trade.
The United States built unprecedented financial and information networks.
The next global leader may be the nation that learns to generate, distribute, and govern intelligence itself on an unprecedented scale.
The strategic resource of the future may not be oil or territory.
It may be cognition.
History Moves at the Speed of Connection
Looking back across history, a common pattern becomes impossible to ignore.
History is not driven solely by heroes or villains.
It changes when the connections between people suddenly become faster, broader, and more powerful.
A new road is built.
Ships become faster.
Capital crosses borders.
Information travels farther.
A new technology emerges.
And worlds that once remained separate are suddenly brought into contact.
Old political orders begin to dissolve.
New civilizations take shape.
History accelerates whenever the speed of connection accelerates.
That has been true of the Silk Road.
It was true of the Mongol Empire.
It was true of the Age of Exploration.
It was true of the Industrial Revolution.
And it remains true today.
Yet the transformation unfolding before us is fundamentally different from any that came before.
Previous revolutions accelerated the movement of people.
Or goods.
Or armies.
Or information.
Artificial intelligence is accelerating something even more profound.
For the first time in human history, what is rapidly accelerating is not simply the movement of knowledge—
but the speed at which knowledge itself is created, analyzed, and transformed into decisions.
That may prove to be the greatest historical turning point of all.
The next great empire may not be defined by the land it controls, the oceans it sails, or even the wealth it possesses.
It may be defined by its ability to cultivate, amplify, and wisely govern intelligence.
