The history of Europe in the seventeenth and eighteenth centuries is often told in
terms of a series of wars. Some of these wars came to have specifi c names, and some did
not; some of them involved long-standing confl icts over trade and territory that fl ared
into actual warfare from time to time but simmered continuously. There were general
Europe-wide wars, such as the Thirty Years War of 1618–48. There were regional wars,
civil wars, naval wars, and wars about who would succeed to various thrones when
rulers died childless or without male heirs. There were revolts against rulers, particularly
in the 1640s to 1660s, which fi rst led historians to call this a time of “crisis.” Wars
that started in the New World came to involve Europe, including the war for American
Independence (1775–83), which eventually included England, France, Spain, and
the Netherlands. European wars also spread outward, including the Seven Years War
(1755–63), which came to be fought in North America (where it was called the French
and Indian War) and India, as well as in Europe.
Most of these wars involved frequently shifting alliances, some of them open and
some of them secret. They were often ended by treaties involving only some of the participants,
so war in one theatre dragged on after fi ghting stopped elsewhere, with rulers
shifting their armies and navies. The treaties of Nijmegen in 1678 to 1679, for example,
which ended one of the many wars that pitted France and its allies against the Netherlands
and its allies, were actually six different peace treaties, all separately brokered.
This pattern of shifting alliances and complex treaties was set by the Thirty Years
War, which many historians see as the fi rst “modern” war in terms of tactics, organization,
and level of devastation. As noted in chapter 5 , the Thirty Years War can also be
seen, at least in its initial stages, as round 3 in the series of religious wars that resulted
from the Reformation. Round 1 had ended with the Peace of Augsburg in 1555, and
round 2 with Henry IV of France allowing French Protestants limited freedom of worship,
and a truce in 1609 between the Netherlands and Spain.
The Peace of Augsburg ended religious wars in central Europe for over fi fty years,
but it was an uneasy peace. The terms of the treaty recognized only Lutheranism
and Catholicism as allowable denominations, but in the second half of the sixteenth
century Calvinism was more dynamic. Some states became Calvinist, ignoring the
terms of the treaty. A few bishops converted from Catholicism to Lutheranism, taking
their territories with them, to the dismay of the Catholic Church. Jesuit preachers and
scholars converted Lutheran princes back to Catholicism, and territories sometimes
switched denominations with every generation, as rulers backed whatever religion
their father had opposed. In 1608, Lutheran rulers formed a military alliance called the
Protestant Union, and in the following years Catholics responded with the Catholic
League.
Dynastic considerations mixed with religion to turn this tense situation into open
warfare. Dismayed at the failure of his efforts to secure religious unity, Emperor
Charles V had abdicated in 1556, dividing his vast holdings between his son Philip II
(who got Spain, the Netherlands, and the Spanish empire) and his brother Ferdinand I
(who got Austria and other central European holdings, and the title of emperor). The
Habsburg family was thus divided into a Spanish and an Austrian branch, though both
supported each other and were fi rmly Catholic. In 1617, Ferdinand of Styria, a Habsburg
cousin, was chosen king of Bohemia (in what is now the Czech Republic), an area that
had rejected the Catholic Church a century before Luther and was overwhelmingly
Protestant. When Ferdinand began to close Protestant churches, Bohemian offi cials
objected, and threw two of his representatives out of the window in Prague. They did
not die – depending on your point of view, they were saved either by angels or by a pile
of manure – but the incident led to civil war in Bohemia.
Armies of the Catholic League and the Protestant Union joined the fi ght, and in the
fi rst years the Catholics were overwhelmingly successful. Ferdinand, who had meanwhile
become Holy Roman Emperor with the title Ferdinand II (ruled 1619–37), wiped
out Protestantism in Bohemia with forcible conversions. He appointed a wealthy
Bohemian nobleman, Albrecht of Wallenstein (1583–1634) as general of the imperial
armies, who continued scoring victories against Protestants, including not only
German troops but also those sent by the king of Denmark. Wallenstein was an effective
leader and ruthless entrepreneur, raising an army – by forcible conscription as well
as promises of pay – that eventually numbered over 100,000, supplying them through
extortion and confi scation. It looked as if Ferdinand might be able to accomplish what
had eluded his great-uncle Charles V: the creation of a large, strong Catholic state in
central Europe under Habsburg rule. In 1629 he passed the Edict of Restitution, which
forbade Calvinism and ordered all lands that had become Protestant since 1552 to revert
to Catholicism.
The prospect of a strong Empire under Habsburg domination frightened not only
Protestants in Europe, but also Catholic opponents of Habsburg power, especially
France. In the early 1630s, well-disciplined and well-armed Swedish troops, under the
leadership of King Gustavus Adolphus (ruled 1611–32) and bankrolled by the French,
successfully defeated Catholic forces several times, though Gustavus Adolphus died at
the Battle of Lützen. Wallenstein was accused of conspiracy with the French, and was assassinated
at the emperor’s orders. Ferdinand II decided to dissolve the Catholic League
and make peace with the German Protestant princes, but this Peace of Prague (1635) did
not satisfy either the Swedes or the French. France sent troops against those of the emperor
and his Habsburg cousins in Spain; Spanish forces were defeated in naval battles
with the Dutch and by the Portuguese, who revolted against Spanish rule in 1640 and
declared themselves an independent country again. The war had become a Europe-wide
war, with territorial aims now more important than religious allegiances.
Each side won battles, but was not able to exploit its victories, and the war dragged
on, with devastating effects. Troops were often recruited by independent military contractors,
of which Wallenstein had been the most successful, with promises of pay and
plunder, and little training or discipline. There were no clear lines of battle, so that
these mercenary armies indiscriminately burned crops and villages and killed animals
and people. Hunger and disease, including dysentery, plague, and syphilis, accompanied
the troops and the refugees who fl ed from place to place. Some historians estimate
that at least one-quarter and perhaps as many as one-third of the population of
the Empire died during the course of the war, though total devastation was localized.
Such civilian losses would not be matched again until the wars of the twentieth century.
Finally, in 1645 negotiations were begun in two cities in the German province of
Westphalia, but it took three years for the terms of a peace treaty to be agreed upon,
with armies sporadically fi ghting and living off what was left of the German countryside
during that time.
The resulting Peace of Westphalia recognized certain political realities in Europe,
but did not lead to lasting peace. It recognized the United Provinces of the Netherlands
and Switzerland as fully independent, and made the larger principalities within the
Holy Roman Empire effectively sovereign, though the Empire itself also continued to
exist. France gained territory on its eastern border, and Sweden gained most of the
German North Sea coastline, which enhanced the prestige of the monarchy in both
countries. Territorial rulers in the Empire were given the right to choose the religion
of their territories, with Calvinism joining Catholicism and Lutheranism as an acceptable
choice. There were more than a hundred other clauses, largely confi rming various
princes’ rights over certain territories, though occasionally stipulating transfers of land
or new titles. The religious lines of division in central Europe were largely fi xed, with
most of northern Germany Protestant and most of southern Germany Catholic. The
Habsburgs largely retained their family holdings and claims on the imperial title. As
it had in the sixteenth century, the basic confl ict in Europe continued to pit France
against the Habsburgs, especially as the Peace of Westphalia had not included stipulations
about the war between France and Spain, which continued.
The Thirty Years War set the pattern for later wars in many ways, but it also provided
lessons about what not to do for more astute military commanders and political leaders.
The biggest problem was logistical, not tactical, for supply systems could not keep
up with troops. Roads were primitive or nonexistent and rivers could not be found
everywhere. Armies had to stop every three or four days to let the millers and bakers
who accompanied the troops catch up and bake the rough bread that was the soldiers’
standard ration, and let the wagons with tents and other supplies catch up. Looting
supplies from the surrounding countryside only worked for a short time, for farmers
in most parts of Europe lived near subsistence level themselves and had little food to
spare. In fact the most impressive aspect of Ottoman armies – which were not involved
in the Thirty Years War, although they were in other seventeenth-century confl icts –
was not their enormous size, but the relatively effective way they were supplied. Even
the Ottomans could not sustain large armies in the fi eld for many months, however,
and shorter wars with limited objectives were more likely to produce clear-cut outcomes
than those that dragged on for years.
Even these shorter wars – of which there were many in the 150 years after the Peace
of Westphalia – were fought with larger and more deadly standing armies, however. By
the middle of the eighteenth century, Brandenburg-Prussia, one of the larger states in
Germany, tried to sustain a permanent army of about 80,000 troops with a population
of perhaps 3.5 million; during the Seven Years War, this army increased to almost
150,000, or about one-quarter of all adult males. Most eighteenth-century armies were
equipped with reliable fl intlock muskets that no longer needed a separate match to
fi re, bayonets on the end of those muskets, and more accurate and mobile artillery. The
best-supplied soldiers had cartridges in which shot was prepackaged with gunpowder,
and the best-disciplined had spent long periods training and drilling. These technical
improvements increased battlefi eld casualties signifi cantly, with losses sometimes approaching
one-quarter of all the troops deployed in the fi eld. Better weapons, bigger
armies, longer training, and fuller supply systems all signifi cantly increased the costs
of warfare. Pressures of war fi nance enhanced the power of some monarchs, including
those of Brandenburg-Prussia, while derailing the expansion of royal power elsewhere,
most dramatically, as we will see below, in England.
Improved training and increasing specialization affected warfare at sea as well as on
land. During the sixteenth century, most states relied on merchant ships temporarily
armed with a few cannon for their naval battles, but it became increasingly clear
that specialized gun-armed warships and merchant ships built to carry a substantial
number of guns were more effective. Between 1652 and 1678, the English and the Dutch
fought a series of wars for control of the English Channel and the North Sea, which
involved larger and larger sailing ships armed with heavier guns, arranged in a formal
line of battle and fi ring continuously. Such tactics required professionally trained offi
cers, well-drilled gun crews, and disciplined sailors who could maintain clear battle
lines.
In the eighteenth century, the Dutch preferred neutrality, concentrating on defending
and supplying their worldwide trading network. The British continued to expand
their navy, becoming the world’s dominant sea power; measured in terms of total
weight, the British navy in 1790 was almost ten times what it had been in 1650, a fi gure
that refl ects both the greater number and the larger size of ships. The French and
the Spanish also built up their battle fl eet strength, largely to challenge Britain in the
Atlantic, while in the Baltic, Denmark, Sweden, and Russia expanded their navies. By
the end of the eighteenth century the Russian navy was the third largest in Europe (after
Britain and France), confronting the Ottomans in the Black Sea and the Mediterranean
as well as the Scandinavian states in the Baltic.
The development of colonial empires and international trade meant that European
wars in the later seventeenth and eighteenth centuries often spread beyond Europe
itself. (In some ways, the Thirty Years War can be seen as the last “pre-modern” war
as well as the fi rst “modern” one, because it was at least initially motivated by religion
and was limited to Europe.) In the Anglo-Dutch Wars, British ships attacked Dutch
holdings in Africa, the West Indies, and North America, eventually gaining New Amsterdam,
which was renamed New York. During the 1630s, the Dutch challenged the
Portuguese in Brazil, and the British captured part of French Canada, though they later
gave it back. During the War of the League of Augsburg (1689–97), French and British
colonists in North America massacred each other, while during the War of the Spanish
Succession (1701–13), the British attacked Spanish forts in Florida and the French attacked
Portuguese Brazilian ports. The colorfully named War of Jenkins’ Ear between
Spain and Britain (1739–48) started after an English sea captain appeared before Parliament
with his ear, claiming it had been cut off by Spanish authorities boarding his ship
in the Caribbean. During the War of the Austrian Succession (1740–8), French ships
captured British-held Madras in India, while British colonists captured Louisburg in
Canada from the French.
The Seven Years War (1755–63) was so global in scope that it could almost be called
the fi rst “world war,” involving confl ict in North America, the Caribbean, the Pacifi c,
and India as well as Europe. As in other early modern wars, logistical problems proved
as important as battlefi eld losses in determining the fi nal results.
The Seven Years War also involved new lines of alliance and hostility that refl ected
changing realities of power. During the sixteenth and seventeenth centuries, the major
line of antagonism in Europe was hostility between France and the Habsburgs. As we
saw in chapter 3 , this had resulted in wars in Italy, Switzerland, Spain, and elsewhere,
and in France coming in on the side of the Protestants during the Thirty Years War. As
the British navy and British colonial holdings expanded during the seventeenth and
early eighteenth centuries, however, France worried increasingly about British power,
while Britain worried about France, which was the strongest and wealthiest country
in Europe in the seventeenth century. After 1688, as we will see in more detail below,
monarchs in Britain came from the ruling houses of two medium-sized states in the
Netherlands and Germany, so they had continental territories to defend. The Austrian
Habsburgs continued as the strongest power in central Europe, but by the middle of
the eighteenth century they were increasingly worried about Prussia, a state made up
of scattered territories within and to the east of the Holy Roman Empire, whose rulers
were establishing an enormous and well-disciplined army. Russia, which had played no
role in the religious and dynastic controversies of the sixteenth and seventeenth centuries,
was also worried about Prussia, and had expansionary plans of its own.
This complicated scenario led, in 1756, to Great Britain making an alliance with
Prussia, to which France, Russia, and the Austrian Habsburgs responded with a triple
alliance. War broke out between France and Britain in North America, in part because
settlers from both countries were staking out claims in the Ohio Valley, and between
all the allies in Europe. In terms of economic might and military manpower, the triple
alliance was much stronger than Prussia, but the ruler of Prussia, Frederick II (ruled
1740–86; known as Frederick the Great), was a brilliant military strategist who understood
how to use different types of troops – infantry, cavalry, and artillery – very
effectively. He attacked Austria, and his opponents were slow to respond and did not
cooperate with one another. British blockades of French ports and victories over the
French fl eet in naval battles meant that France could not resupply its forces in either
North America or eastern Germany, and in 1760 the French governor surrendered all
of Quebec to the British. Spain joined in on the side of France, and the British captured
both Spanish and French colonies, including Cuba, the Philippines, French islands in
the Caribbean, and French forts in Africa and India. Two separate peace treaties fi nally
ended the war in 1763, with France losing most of its overseas colonies, Spain ceding
Florida to Britain but gaining back Cuba and the Philippines, and Prussia being confi
rmed in its takeover of the territory of Silesia from Austria.
In contrast to the Thirty Years War, the Seven Years War was truly “modern”: fought
over territory and trade by professionally trained and relatively well-supplied troops,
with naval operations and new military technology used effectively. The treaties of
1763, however, were no more successful than the Peace of Westphalia in ending hostilities
for very long. Prussia and Austria went to war again in 1778 over who would inherit
the throne of Bavaria, a large state that bordered Austria in the southern part of the
Holy Roman Empire. In the same year France entered the American Revolution on
the side of the colonists, and later Spain and the Netherlands did as well. The Treaty of
Paris in 1783 that recognized the independence of the thirteen British North American
colonies transferred other colonial territories – Tobago and Senegal – from Britain to
France and reaffi rmed Spanish rights over Florida. (Spain ceded Florida to the United
States in 1819.) Just a few years later, however, the French Revolution and its aftermath
would once again set most of the powers of Europe against each other.
By their very nature, wars generally involve external relations between states. Those
relations – and success or failure in war – were shaped by internal political developments
in the countries and empires of Europe. The internal political history of each
state is somewhat distinct, so that the following sections look at different countries separately.
There are certain themes that we can follow in all – or at least most – of them:
an expansion of centralized authority, whether held by a monarch alone or shared by a
representative body; the continued development of government bureaucracy; and the
pursuit of territorial power and colonial wealth.
