The Thirty Years' War was a brutal conflict. Europe in the 17th century was consumed

0:05

in flames. The war knew no rest, the fields were devastated and hunger and death

0:12

had become daily bread. In my last video about the Spanish Tercios,

0:18

we saw how some of the most iconic battles took place in that period,

0:22

but today we are going to go further. We will talk about the end of that chaos, about how the Peace of Westphalia

0:28

changed the course of Europe forever. And that very long war that began

0:33

as a religious struggle and ended up involving almost all the

0:37

European powers, was a war that left in its wake devastation and incalculable losses. But

0:43

after three decades of battles, peace came to end the bloodshed and bring a

0:49

new order. So join me to discover how this treaty redrawn the European map,

0:54

changed the rules of the game and established the foundations of the international system we know today.

1:00

I'm JJ Priego, this is Stories of History, and here the story is told in another way. Do you want

1:07

to know more? Join me! INTRO

1:25

Imagine an exhausted continent, with thousands of razed cities, abandoned fields and millions

1:32

of lives lost. The Thirty Years' War was the last major European conflict motivated

1:38

by religious divisions and one of the most devastating in European history, with a balance

1:44

of approximately Beware! 8 million dead. Europe was a true mosaic of

1:50

temporary alliances, betrayals and confrontations that only sowed more chaos. But, finally, the

1:56

desire for peace prevailed, and the first steps were taken towards a new way of understanding relations

2:01

between states. The Peace of Westphalia was not only the end of a conflict,

2:07

but also the beginning of a new era. The Thirty Years' War, which began in

2:12

1618, more than 400 years ago, was a conflict that involved much of Europe and involved

2:19

several nations. At the center of the conflict was the Holy Roman Empire

2:25

, where the emperor, supported by the Catholic states, faced several

2:31

Protestant states. France, although Catholic, fought against the Holy Empire and Spain with the aim

2:38

of weakening the Habsburg dynasty, which represented its main rival in Europe.

2:43

Spain, an ally of the Holy Empire, was involved in this conflict not only to

2:48

support the Habsburgs, but also in its own fight against the United Provinces, that is,

2:54

the Netherlands, with whom it was maintaining the Eighty Years' War. On the other hand, Sweden,

3:00

under the command of King Gustav II Adolf, intervened in the war to support the Protestants of the

3:05

Holy Empire and increase their influence in northern Europe. Denmark also initially participated

3:11

to defend the Protestants, but after a defeat, it withdrew from the conflict.

3:17

England, although it did not intervene directly in the military conflict, offered financial support to

3:23

the Protestants, especially the Netherlands. Meanwhile, Portugal and Catalonia

3:28

took advantage of the situation to rebel against Spanish rule and seek independence.

3:34

At the origin of the conflict, Bohemia played an important role when it rebelled against

3:39

Habsburg rule, causing the start of the war. Throughout this conflict,

3:45

numerous German petty princes, both Protestant and Catholic, clashed

3:51

with each other and with foreign powers. And other nations such as Transylvania and

3:55

Poland-Lithuania also had minor or sporadic participation in the conflict, which

4:01

established the Thirty Years' War as one of the largest and most devastating conflicts.

4:07

At first, the war emerged as a fight between Catholics and Protestants,

4:12

but… over time, it became a battle for political power,

4:16

territorial hegemony, and continental dominance. Imagine a Europe divided into

4:22

shifting alliances, with armies marching back and forth, and a continent mired in uncertainty

4:28

for thirty years. It was a period of chaos, uncertainty and brutality that

4:31

seemed to have no end. The war was a conflict between states,

4:35

an ideological and religious struggle that transformed the destiny of Europe. Every battle, every decision

4:40

politics and each alliance forged in those years, left deep marks in the history of the continent.

4:46

This conflict was a battle of armies, a war of resources and also

4:50

a fight for economic survival. The economies of all the belligerent countries

4:55

were eroding over the years, resources were quickly depleted and the population,

5:01

as always, suffered the most devastating consequences. In the lands of the Holy

5:07

Roman Empire, civilians were the most affected, falling victim to the constant

5:12

military campaigns that devastated their villages, fields and cities. Famine, disease and

5:18

insecurity became daily life for the civilian population. Civilian suffering

5:24

worsened with each passing year, and many communities were completely uprooted.

5:31

A war that left deep wounds in the psychology of the European population. For many

5:36

people, hope for a future of peace and stability seemed to have faded. The

5:43

constant mobilizations of troops, looting, and the destruction of crops made

5:49

daily life extremely difficult. Despair spread,

5:54

and entire generations grew up without knowing a moment of peace. For example, in Germany

6:01

it is estimated that a third of the population perished due to conflict, famine and disease. The war caused

6:06

a serious economic collapse in Central Europe, leaving many territories

6:11

impoverished and with their infrastructure destroyed. Epidemics, such as typhus and plague,

6:17

spread rapidly among soldiers and civilians, as the constant movement

6:23

of troops and poor hygiene helped these diseases spread,

6:29

greatly increasing the number of deaths. In social terms, the war left a

6:35

lasting mark on the affected regions. The depopulation of large areas,

6:39

the loss of arable land and the collapse of the agrarian economy contributed

6:44

to the emergence of peasant rebellions. But, as I say, apart from the battlefield,

6:49

the war also developed into an intense diplomatic war, where alliances were

6:55

constantly formed and broken, often in a matter of months or even weeks. The Habsburgs,

7:02

allied with Spain, faced a shifting coalition of European powers,

7:07

including France, Sweden, Denmark, and several German states. Politics became

7:12

so complex that many kings and rulers lived in a constant state of negotiation and betrayal,

7:20

always seeking their own benefit at the expense of the suffering of others. This

7:25

political complexity caused the conflict to last for three long decades.

7:31

France and Sweden took every opportunity to weaken Habsburg

7:35

influence and gain territorial advantage. Meanwhile, Spain struggled to maintain its

7:41

territories and protect its trade routes, facing enemies on multiple fronts.

7:47

This combination of military and diplomatic conflicts made the

7:51

Thirty Years' War one of the most complex and devastating episodes in European history,

7:57

whose resolution would only come after absolute exhaustion of all sides involved. And

8:04

the millions of deaths represented one of the greatest human tragedies of modern Europe.

8:09

But today I don't want to detail the Thirty Years' War, since so many things happened

8:15

that I would need several videos. What, by the way, if you want me to get into it,

8:19

put it in the comments. And I promise you that I will detail this war in more detail. But today

8:24

I want to talk to you about how peace was forged. Well, around the 1630s,

8:30

some European leaders began to seek peace, although initial efforts failed.

8:37

Attempts at mediation between France and the Holy Empire in 1638 did not produce results

8:43

due to a lack of French interest, which still saw military opportunities. At this time,

8:49

France was more concerned with its rivalry with Spain than with reaching a general agreement.

8:56

And it was in December 1641, 11 years later, when it was finally agreed to begin

9:03

formal negotiations for peace. Peace conferences were organized in the German cities of

9:08

Osnabrück and Münster, and in the summer of 1643, the first diplomats began to arrive. The

9:17

Negotiations were slow and difficult, with envoys from France, Sweden, Spain,

9:22

and the Holy Empire, among others. The logistics of the negotiations also complicated matters,

9:28

as diplomats had to send messages to their respective capitals, which took weeks.

9:34

The military situation also played a crucial role in the development of the talks. The defeat

9:39

of the Holy Roman Emperor Ferdinand III at the Battle of Jankov in 1645 and

9:46

France's need to concentrate on its war against Spain made both sides more

9:51

willing to negotiate. Sweden, for its part, rejected a mediator proposed by Denmark,

9:57

but two neutral figures were finally agreed upon: the papal legate Fabio Chigi

10:02

and the Venetian envoy Alvise Contarini. And as the conflict dragged on,

10:08

more and more parties involved saw the need to end the war. The Battle of Prague in

10:13

1648 and internal pressures in the Holy Empire convinced Ferdinand III of Habsburg that peace

10:20

was the only viable option. Thus, on October 24, 1648, after four years of intense

10:27

negotiations, the Treaties of Westphalia were signed in the

10:32

aforementioned German cities: in Osnabrück between the Protestant powers and in Münster among the Catholics.

10:38

This process not only brought an end to the Thirty Years' War, but also to the

10:43

Eighty Years' War between Spain and the Netherlands. And although peace between France and Spain was delayed,

10:49

the treaty established a new order in Europe. He recognized the independence of

10:54

Switzerland and the United Provinces, strengthened Sweden and France with territories, and guaranteed

10:59

religious freedom for Calvinism. The Peace of Westphalia was the first

11:04

modern diplomatic congress, where representatives of almost all major European states

11:10

met to negotiate peace. And it was attended by 150 delegates from the states

11:15

involved. An extremely complex treaty, but the results were revolutionary.

11:22

The agreement brought peace and also redefined what it meant to be a state. It was here that

11:28

the concept of national sovereignty was born, putting an end to the feudal idea that territories were

11:34

simple properties of monarchs. Each state now had the right to decide its own religion

11:40

and govern itself without outside interference. Religion, which had been the trigger

11:46

for so many conflicts, was no longer the main cause of war in Europe. Furthermore,

11:52

the same legal rights were recognized for Catholics, Lutherans and Calvinists,

11:58

thus eliminating the idea of ​​a homogeneous Christian Europe. It also meant the recognition that

12:03

diplomacy and negotiation were essential to maintaining stability on the continent.

12:09

Instead of resorting to war, states were beginning to accept the importance

12:14

of diplomatic solutions to resolve their differences. The treaties of Osnabrück and Münster

12:19

were the pillars on which this new order was built, and the idea that all states

12:24

were equal in rights, regardless of their size or power, was a true revolution for the time.

12:31

That is, before the Peace of Westphalia, countries or kingdoms could meddle in

12:36

other people's affairs without asking permission, and if you didn't like what they did, you could invade them or try to control them.

12:43

But with this agreement, for the first time in history, countries began to

12:47

understand that each state or nation is like a "house" and that no one has the right to enter

12:52

that house or tell it what to do without being invited. It was recognized that all countries are independent

12:59

and have rights that cannot be taken away, such as the right to govern themselves and

13:04

decide what is best for their people. And the principle of non-interference

13:08

means that no one can interfere in the internal affairs of another country.

13:13

Each nation has the right to handle its own problems without others interfering.

13:18

This new approach was super important because it helped reduce wars between countries and

13:23

create a system where nations learned to respect each other. Or at least in theory. If

13:30

not, a framework had been created for it. And today, many of the rules that govern the world,

13:35

such as diplomatic relations and international law, are based on this idea that

13:40

Each country has its own space and decisions, and everyone must respect it.

13:45

And of course, this change in perspective was key to the development of the concept of balance of power,

13:50

which would remain the basis of international politics for the following centuries.

13:55

And therefore, the consequences of this treaty were profound and lasting. First,

14:01

a framework was established for future diplomatic negotiations, which would inspire the creation of

14:05

international conferences and congresses in the 18th and 19th centuries. This was the germ of what

14:12

would eventually evolve into multilateral organizations such as the United Nations.

14:17

Furthermore, the recognition of state sovereignty transformed the way

14:22

countries interacted. As I told you, now, each state had the freedom to choose its religion and

14:28

govern itself according to its own interests, without fear of external interference. An independence

14:34

that was a great step towards the creation of nation-states as we know them today.

14:40

Finally, the Peace of Westphalia had a direct impact on the political structure of Europe.

14:45

As I told you, France gained ground. Since it secured important areas in Alsace and

14:51

the Rhineland border, which consolidated its position as the new emerging European power. Sweden,

14:57

although it gained territories, such as Western Pomerania and strategic enclaves in the North Sea and the

15:03

Baltic, gaining influence in the Holy Empire, soon faced difficulties in maintaining its

15:08

dominance in Germany, due to competition with other states such as Brandenburg-Prussia. And

15:15

the independence of Switzerland and the United Provinces, the Netherlands, were also recognized.

15:20

For the Holy Empire, the consequences were profound. The German princes gained

15:26

greater autonomy, which weakened the emperor's authority. This internal fragmentation led

15:32

to a more decentralized structure, where the approximately 360

15:37

German states could manage their own affairs, including in foreign policy,

15:42

although without being able to confront the emperor directly. This, in practice, emptied

15:47

the imperial title of its content, which weakened the cohesion of the Holy Empire. A fragmentation

15:52

that would be one of the factors that would prevent German unification until the 19th century.

15:57

The conflict also favored the consolidation of new maritime powers such as England and

16:03

the Netherlands, which emerged stronger after the war. Meanwhile, France still had to

16:08

resolve its rivalry with Spain, which would continue to fight against French rule. Spain,

16:14

which had been a great power in Europe, a hegemonic power, began its decline

16:20

as a result of this prolonged struggle. Another of the most significant aspects was

16:26

the recognition of religious freedom, which included the Calvinists, and the confirmation of

16:31

the Peace of Augsburg of 1555. This agreement allowed princes to impose their religion in

16:40

their states, but also guaranteed rights to religious minorities. This recognition

16:46

ended more than a century of religious wars that had devastated Europe. A change that laid

16:52

the foundation for a Europe where politics and religion began to separate, allowing

16:58

secularism to gain ground over time. Ultimately, the Peace of Westphalia was much more

17:04

than the end of a conflict. It was the beginning of a new era, a decisive moment in history that

17:10

laid the foundations of the modern international system. The agreements reached in 1648 redefined the

17:17

concept of the state, sovereignty and diplomacy, and their effects are still felt today. The

17:24

Thirty Years' War and the Peace of Westphalia forever changed the face of Europe, and their legacy

17:29

lives on as a reminder of the importance of diplomacy and the price of war.
