Abstract
Time of Risorgimento in Italy was, not only historically, but also politically and culturally very
important. At the beginning of the 19th century, national consciousness began to rise among the people
of Italy. In this paper, it will be shown how this phenomenon influenced cultural, and especially
musical life at the time. One of the most important figures of the 19th
century Italy was Giuseppe Verdi
(further in text: Verdi), an opera composer. A lot of intrigues were attached to him, mostly because of the
content of his operas. It seems it could not be decided if his operas were purely national and patriotic, or
political. One chorus in particular - ´Va pensiero´ - became the focus not only for journalists of that time,
but also in last fifteen to twenty years, where scholars are dedicating a lot of attention to it. On that note
this paper will also be focused on the reception and meaning of that part of the opera Nabucco.
Keywords:
Risorgimento, opera, Verdi, Nabucco, ´Va pensiero´, politics Introduction
In the time 1815 – 1870, Verdi wrote the opera Nabucco (1841). This era was known as the
time of Risorgimento – time when the Italians wanted to form their fatherland and separate
Italy from Habsburg monarchy. During the restoration period (1814 – 1846-47), there were
attempts at revolution, but mostly driven by the small minorities, moved by universal ideals.1
Even before Verdi there were composers whose operas were considered nationalistic,
but Verdi is, after all, the biggest and the most important example of those nationalistic ideas.
A lot of intrigues were attached to him, mostly because of the content of his operas. It seems it
could not be decided if his operas were purely national and patriotic, or political. “The
accepted view – which is only now beginning to be questioned – is that he was a nationalist
from the start, that his operas gave voice to straightforward Risorgimento nationalist feeling,
and that contemporary audiences understood them to do so.”2 The biggest issue, as it will turn
out to be, is chorus ´Va pensiero´ from the third act of Nabucco opera, later unofficial

national hymn of Italy, where it is sang about nostalgia and sadness for lost fatherland.3 After
´Va pensiero´ there will be some other choruses from Verdi´s operas which will also have an
important role, as the one from Nabucco, but in this paper main focus will be on the myth and
the reception of this particular chorus, as well as the meaning and understanding of it. But at
the very beginning, in order to understand the work of Verdi, we must first understand the
political and social environment in which this composer lived and created.
Italian Risorgimento in connection with music
The term Risorgimento can be explained in two ways. On one hand it can be understood as a
synonym for the Italian national movement, and on the other hand as a name for a certain
period of Italian history, in which case, the precise moment of the beginning and overall
duration, was never agreed on among the scholars.4 Either way, “this historical process that
led to the founding of the Kingdom of Italy in the 19th century seems inseparable from
music.”5 That is also why the mentioned urge of the Italians reflects itself in work of opera
composers, but not only that, it has also left the mark among the writers of that time.6 In this
paper, however, the focus will be on the relation between Risorgimento and music.
The mentioned conjunction appears in a work of Giuseppe Mazzini - in Filosofia della
musica (1836) to be precise - where he encourages the composers to replace their
individuality with a new musical style by giving the bigger role to the chorus, and by using
themes or motives in order to achieve more precise characterization.7 This music-theoretical
publication is one of the few to be written on the basis of the idea of Risorgimento, and also
was dedicated to one unknown genius, who will, hopefully create ´Musical drama of the
future´.8 It is one of the mystifications from the older Risorgimento literature, that Verdi was
the one to be considered to be this unknown genius, although that was never confirmed by

Mazzini himself.9 Had that been pointed out, there were few composers more whose names
were associated with the national movement, such as Bellini, Rossini or Pacini,10
but in fact
none of them had the amount of attention, none of them was watched so closely, and none of
them was written about as much as it was about Verdi. Therefore “until this day, as a living
image of the ´political´ composers, Verdi presents a convincing supporter of the Italian
national movement, which would have through his works, namely due to performances of the
operas from Nabucco, to La battalgia di Legnano, provided an important contribution to the
unity of the country.”11
However, there are some things that are just not consistent with this claim. First of all,
in three of his operas (Ernani and In due Foscari, 1844, and Macbeth 1847) Verdi did follow
Mazzini´s advice, and had experimented with the themes for main characters, which is why
these operas were so distinguished from his earlier work in Nabucco (1842) and I Lombardi
(1843).12
The content itself is different in them, too – while Ernani, In due Foscari and Macbeth indeed can be allegorically interpreted in a way to describe the current situation
between Italians and Austrians at the time, Nabucco and I Lombardi, on the other hand have
religious content.13
In fact, the only opera ever written specifically for the purposes of
Risorgimento is La battaglia di Legnano (1849),14
and that was after the revolutionary year of
1848. Later in time, Verdi did compose Inno popolare (“Suona la tromba”) after the text with
patriotic content which was given to him by Mazzini, and afterwards, disappointed by retreat
of the Italian revolutionists who were not anymore in need of the new hymn, he completely
retired himself from political scene in Italy, and moved away to Paris, where he wrote the
opera Les vêpres siciliennes (1855), which does not take any sides in the current political
conflict.15
“A decade later, in Don Carlos (1867), Verdi reexamined his own youthful
revolutionary fervor, so the opera could be heard as a summation of Verdi´s relationship to

politics, as multi-voiced as Verdi´s own statements.”16
Now, after taking in consideration all
these information, one question still remains, and it repeats itself constantly – why is then, if
everything happened this way, Verdi considered as a supportive revolutionist, and his chorus
´Va pensiero´ as a representative music of Risorgimento?
The legend of ´Va pensiero´ “Nabucco (first performed at La Scala, Milan in March 842) has always held a special
position among Verdi´s early operas.”17
We are constantly reminded by the lack of original
documentation, which is the case with this opera, that the opera itself was the reason why the
composer became known for it.18
With the absence of first-hand material, authors were
unfortunately obligated to follow different narratives to be able to “put all the pieces
together”, in order to get the whole story on what really happened during the time of
composition of Nabucco, where the hardest part was actually the fact that, most likely, Verdi
himself told, or gave permission for the accounts to be told.19
So-called Autobiographical
Sketch, which was, as far as the belief goes, dictated to the publisher Giulio Ricordi on 19th
October 1879 by the composer personally, represents the most valuable of the mentioned
accounts and, although it turned out unreliable in many occasions, it must be considered that
it is very hard to ignore the imagination that public created over time.20
With the very first
big success that Nabucco brought to the young composer, it is only natural for the most
known of the Risorgimento anecdotes to date back from this moment in Verdi´s life.21
As far as the legend goes, “[…] details vary, but stories of the political uses of Verdi
during Risorgimento tend to concern choruses, and they usually center around spontaneous
outpouring of emotion, moments when Verdi´s music enabled the populace to express
patriotic sentiments.”22
Now, the words of ´Va pensiero´ were actually about Hebrew slaves,
but at the same time, the audience could recognize the real meaning and the purpose of this

chorus, which was to express the overall feeling among the people of Italy – the sadness and
nostalgia for their fatherland.23
On the other hand, even with knowing the “truthful” meaning,
and seeing through composers intention, audience was never rebellious, because “the patterns
of melodic repetition create musical symmetry and closure, but never attempt to illustrate
individual words or ideas from the text, and as nostalgic invocation of nation ´Va pensiero´ is
exemplary, but it carries no impulse toward action, change, or movement that might inspire
supposed patriotic outbursts.”24
The topic of Verdi´s role as vate del Risorgimento is very much discussed among the
authors of the recent time, especially because it seems it cannot be decided when exactly the
composer earned this cognomen. “Roger Parker asks “Does it matter vitally whether Verdi´s
reputation as vate del Risorgimento began in 1842, or 1848 or 1859?””25
Parker is also
pointing out that, during the time of preparing the first critical edition of Nabucco, he came to
the discovery that on the opera´s premiere, encore was not ´Va pensiero´, but instead it was
completely different chorus, ´Immenso Jeovha´, which was the Hebrew prayer.26
The
explanation, why after all, Verdi biographers kept the illusion of the ´Va pensiero´ encore,
could be heard in a first few phrases of each chorus, and therefore understood, especially
knowing the contents of them, where there are no political potential, and the pastoral nostalgia
is missing.27
One other peculiar thing happened in 1840s – “in the Gazzeta musicale di
Milano, the house organ of Verdi´s publisher, Ricordi, show that following the Cinque
Giornate, when La Scala closed for several months, opera was replaced by concerts of newly
composed patriotic hymns and military music, but strangely […], Verdi´s name was nowhere
to be found on concert programs.”28
Also, the record publications are showing the same –
during those few months when freedom of speech was at its highest, journalists were writing
almost only about patriotic anthems.29
Nevertheless, name of the vate del Risorgimento is
somehow also not appearing, and what is even more surprising, there are no signs of reprints
of the chorus which was once considered to represent the Risorgimento - ´Va pensiero´ was

not reprinted, not even individually from the opera, for which there is no explanation if it was
indeed as popular as it is believed it has been.30
Verdi – patriotic or political composer? Before entering the details about Verdi and his connection with the Italian national movement,
it is important to point out the diverse definitions that were used by scholars when it came to
the political engagement – “from private interest in the events of the Risorgimento […], to
anecdotes of operatic music, and at the end, once myths and sentimental attachments are
dispelled, what kind of evidence remain?”31
In recent researches there were a lot of approaches regarding this subject, but it is also
important, and at the same time interesting to mention and consider why, even with such lack
of documentation, have the scholars devoted so much of their attention to Verdi´s early career,
and going back in time, even before the 1848.32
It is a long way between assenting that the
composer, among other revolutionists, felt a strong condemn toward Austrians, and wished
them gone from Italy, to the today´s perception of Verdi, in which he and his music are
representative for the national movement, and was therefore singled out from a pool of other
artists, who were also active at that time.33
“With Nabucco and I Lombardi alla prima
crociata – in other words with his first great successes – Verdi began to practice political
action with his music.”34
However, was it really Verdi the one who placed himself in the
political milieu and made himself important figure, or was that the act of the supporters of Risorgimento?
In the year 1848-49, in Rome, Verdi composed two pieces after Mazzini´s desire,
namely the anthem Suona la tromba, as well as the “Risorgimento-oper” La battaglia di
Legnano.35
Thanks to this two works, and the fact that the Italian people were writing “Viva
V.E.R.D.I” (which actually stands for the king´s name - Vitorio Emanuele Re D´Italia) on the

walls of their homes and shouted it at the same time, the composer got the following
reputation of Maestro della Revoluzione Italiana. Nevertheless, the well-known phrase “Viva
Verdi” first appeared in 1858, when the actual liberation of Italy finally came to realization,
and in fact could not be invented earlier, with the idea of unification so far away from
happening, under the King of Savoy´s leadership.36
Back to the year 1848 and so-called
Cinque Giornate, when Austrians were driven form Milan, there was surprisingly little effort
in this city to perform Verdi´s operas, as contrast to the period after the return of Austrians.37
”Milan had by this time experienced several weeks of political and artistic freedom,”38
which
was all more the surprise why Verdi´s name was not appearing, especially being considered as
the Risorgimento symbol. Furthermore, it is undeniable that some of Verdi´s work was, prior
to 1848, suitable for patriotic purpose, and that the composer fully supported the 1848
revolutions.39
At the beginning of January 1861, Camillo Benso, Count of Cavour, former Minister
of the Kingdom of Savoy wanted to form a new Italian government, including politicians and
artists; therefore, on January 10th
he wrote a letter to Verdi, inviting him to join first national
Parliament.40
During his candidature Verdi had problems with another candidate, Giovanni
Mingehli Vaini and did not want to participate, so, as he wrote in his letter to the conductor
Angelo Mariani in the end of January 1861, he wanted to give his resignation, but even so on
February 6th
, when he was elected, he accepted.41
His work in Parliament was not that long.
After hearing about Cavour´s death, Verdi was no longer a devoted member, his participation
was minimal, and besides that, he had planned already a new opera for the Imperial Theater at
Sankt Petersburg.42
“[…] The image of the man and composer may have been exaggerated in
the later part of the 19th
century and however true Verdi´s statement was that his biography
should show that as a “Deputato” he did not exist, it must also show that he was quite rightly
considered by his countrymen one of the leading figures in the Italian Risorgimento.”43

Conclusion
Giuseppe Verdi was undeniably the most popular composer of 19th
century Italy. In this
period, operas were way of communicating, therefore, mostly because of the content of his
operas, Verdi was unequivocally considered to have big and important role in 1848
revolutions. The question that stays, and will still be present after all these years is: was Verdi
purely patriotic oriented in his operas or the politics played part in his work, too?
Unfortunately, absence of the original documents from the time when he wrote Nabucco does
not let us conclude whether is the today´s image of him correct. The only thing in the present
time known for sure is that he was always a great patriot in love with his country, and he
indeed was a political person at one point in the Italian history, but that was after the 1848
revolution for which he is considered to be representative for, and beeing known for his great
patriotism, and considering time of big changes when Verdi lived and composed, it is obvious
that his operas were used for political purposes as much as it was possible.
A lot of questions were also raised when it came to the chorus ´Va pensiero´, but one
event in particularly testifies about its success and its fame, and that is Verdi´s funeral. In the year
1901, under the conductor´s baton of Arturo Toscanini, along with ´La Scala´ choir and orchestra,
the greatest Italian composer of 19th
century was accompanied on his last journey.44
Today, Verdi´s personal opinion and his intentions may not be fully understood and
familiar, but one thing about him never changed - he was loved and respected during the time
he lived and created, and he is still respected for his work. When and why he got the
cognomen vate del Risorgimento, and whether his operas were in political spirit will probably
never be known for sure, but he is definitely going to stay the composer who loved and
supported his nation and his country.
