Vatican Apostolic Archive

<h2 id="secret-name">"Secret" name</h2>
The use of the word secret in the former title, "Vatican Secret Archive", does not denote the modern meaning of confidentiality. A fuller and perhaps better translation of the archive's former <a href="/facts/Latin/pM3Kge85">Latin</a> name may be the "private Vatican Apostolic archive", indicating that its holdings are the pope's personal property, not those of any particular department of the <a href="/facts/Roman_Curia/LJ7r0uay">Roman Curia</a> or the <a href="/facts/Holy_See/7tK8AceC">Holy See</a>. The word secret continues to be used in this older, original sense in the English language, in phrases such as secret servants, secret cupbearer, or secretary, much like an esteemed position of honour and regard comparable to a <a href="/facts/VIP/t9rPfgWP">VIP</a>.<a class="footnote-ref" id="fnref:5" href="#fn:5">5</a> One study in 1969 stated that use of the term secret was merited, as the archives' cataloguing system was so inadequate that it remained "an extensive buried city, a Herculaneum inundated by the lava of time ... secret as an archeological dig is secret".<a class="footnote-ref" id="fnref:6" href="#fn:6">6</a>
Despite the change in name, parts of the archive do remain classified in the modern sense of the word secret; most of these classified materials, which are actively denied to outsiders, relate to contemporary personalities and activities, including everything dated after 1958, as well as the private records of church figures after 1922.<a class="footnote-ref" id="fnref:7" href="#fn:7">7</a><a class="footnote-ref" id="fnref:8" href="#fn:8">8</a>
On 28 October 2019, <a href="/facts/Pope_Francis/F2uNhKC9">Pope Francis</a> issued an Apostolic Letter <a href="/facts/Motu_proprio/5LXJ147I">motu proprio</a> dated 22 October, renaming the archives from the Vatican Secret Archive to the Vatican Apostolic Archive.<a class="footnote-ref" id="fnref:9" href="#fn:9">9</a><a class="footnote-ref" id="fnref:10" href="#fn:10">10</a>

<h2 id="history">History</h2>
<h3>The early Church</h3>
In the <a href="/facts/Christianity_in_the_1st_century/Eg9F8mSt">1st century</a> of <a href="/facts/Christianity/nKyJHlqq">Christianity</a>, the Church had already acquired, and begun to assemble, a sizable collection of records. Known alternately as the Holy Scrinium or the Chartarium, these records normally travelled with the current pope.<a class="footnote-ref" id="fnref:11" href="#fn:11">11</a>
In later centuries, as the Church amassed power, popes would visit heads of state to negotiate treaties or make political appearances around Europe. Popes would also have multiple places of residency. When they travelled for diplomatic or other purposes, they would take their archives with them, since they needed it for administrative work. This resulted in some loss of items.<a class="footnote-ref" id="fnref:12" href="#fn:12">12</a>
Initially, the archival materials of the Church were stored at the <a href="/facts/Lateran_Palace/kHN2Fq8V">Lateran Palace</a>, then the official papal residence.<a class="footnote-ref" id="fnref:13" href="#fn:13">13</a>

<h3>Uprisings, revolts, and the Western Schism (1085–1415)</h3>
By the <a href="/facts/Christianity_in_the_11th_century/KSdyNC4o">11th century</a>, the archives of the church were devolved to at least three separate sites: the Lateran, <a href="/facts/Old_St._Peter%2527s_Basilica/dJVVlK5y">St. Peter's Basilica</a>, and the Palatine palace.<a class="footnote-ref" id="fnref:14" href="#fn:14">14</a> 
When the Popes moved to <a href="/facts/Avignon_Papacy/GQFQFNsV">Avignon</a>, the process of transporting their archives took twenty years, all told. The various places where the archives were kept along the way were sacked by the <a href="/facts/Guelphs_and_Ghibellines/F3nVoLjc">Ghibellines</a> three separate times, in 1314, 1319, and 1320.<a class="footnote-ref" id="fnref:15" href="#fn:15">15</a>
<a href="/facts/Antipope/aYCDyln2">Antipopes</a> also had their own archives. The <a href="/facts/Western_Schism/0RgtA4Ng">Western Schism</a> resulted in two sets of papal archives being developed at once; this rose to three during the era of Pisan antipope <a href="/facts/Antipope_John_XXIII/svyjtf4F">John XXIII</a>.<a class="footnote-ref" id="fnref:16" href="#fn:16">16</a> The disparate archives of the rival papal claimants were not fully reunited in the Vatican's archives until 1784.<a class="footnote-ref" id="fnref:17" href="#fn:17">17</a>
During the 1404 sack of the Vatican, papal registers and historical documents were thrown into the streets, and <a href="/facts/Pope_Innocent_VII/rNR6MRuH">Pope Innocent VII</a> fled the city. His successor, <a href="/facts/Pope_Gregory_XII/2uWztnTM">Pope Gregory XII</a>, supposedly sold off a large number of archival materials in 1406, including some of the papal registers.<a class="footnote-ref" id="fnref:18" href="#fn:18">18</a>

<h3>Founding the archive</h3>
In 1612, <a href="/facts/Pope_Paul_V/62LVJzSj">Pope Paul V</a> ordered all Church records assembled in one place.<a class="footnote-ref" id="fnref:19" href="#fn:19">19</a>

<h3>Seizure by the French government and restoration</h3>
As <a href="/facts/Napoleon_Bonaparte/8TKBIjPM">Napoleon Bonaparte</a> conquered the states on the Italian peninsula in the 1790s, he demanded works of art and manuscripts as tribute. His armistice with Holy See on 23 June 1796 stipulated that "the Pope shall deliver to the French Republic one hundred pictures, busts, vases or statues ... and five hundred manuscripts", all chosen by French agents. The 1798 <a href="/facts/Treaty_of_Tolentino/LJsqUDYJ">Treaty of Tolentino</a> made even greater demands, and the works sent to Paris included the <a href="/facts/Codex_Vaticanus/PKR628K8">Codex Vaticanus</a>, the oldest extant manuscript of the Bible in Greek.
By the time Napoleon became emperor in 1804, he envisaged a central archive in Paris of the records and treasures of Europe. In 1809 he ordered the entire Vatican Archive transferred to Paris, and by 1813 more than 3,000 crates had been shipped, with only modest losses.<a class="footnote-ref" id="fnref:20" href="#fn:20">20</a> The Vatican archives were stored in the complex of the <a href="/facts/Archives_Nationales_(France)/6bgJf6k4">National Archives of France</a>, on the grounds of the <a href="/facts/H%25C3%25B4tel_de_Soubise/R313m50r">Hôtel de Soubise</a>.
In April 1814, after Coalition troops entered Paris, the new French government ordered the archive returned, but provided inadequate financing. Vatican officials raised funds by selling some volumes as well as bundling documents for sale by weight.<a class="footnote-ref" id="fnref:21" href="#fn:21">21</a> Inadequate funding led to losses en route, with one scholar of the period estimating that "about one-fourth to one-third of the archival materials that went to Paris never returned to the Vatican."<a class="footnote-ref" id="fnref:22" href="#fn:22">22</a><a class="footnote-ref" id="fnref:23" href="#fn:23">23</a>

<h2 id="access-to-scholars">Access to scholars</h2>
<h3>19th-century developments</h3>
In 1855, <a href="/facts/Augustin_Theiner/vQUofhUU">Augustin Theiner</a>, prefect of the Archive, began to publish multi-volume collections of documents from the archive.<a class="footnote-ref" id="fnref:24" href="#fn:24">24</a> His predecessor <a href="/facts/Marino_Marini_(bishop)/0aTE1fDk">Marino Marini</a> had produced an account of Galileo's trials that failed to satisfy scholars who saw it as an apology for the Inquisition. Beginning in 1867, Theiner and his successor granted individual scholars access to the manuscripts relating to the trial of <a href="/facts/Galileo_Galilei/98VT2z3v">Galileo</a>, leading to a protracted dispute about their authenticity.<a class="footnote-ref" id="fnref:25" href="#fn:25">25</a> Scholarly access was briefly interrupted following the dissolution of the Papal States in 1870, when archive officials restricted access to assert their control against competing claims by the victorious Italian state.<a class="footnote-ref" id="fnref:26" href="#fn:26">26</a>
In 1879, <a href="/facts/Pope_Leo_XIII/bdovwR3o">Pope Leo XIII</a> appointed as archivist Cardinal <a href="/facts/Josef_Hergenr%25C3%25B6ther/MqQX257a">Josef Hergenröther</a>, who immediately wrote a memo recommending that historians be allowed access to the archive.<a class="footnote-ref" id="fnref:27" href="#fn:27">27</a> Access had remained limited out of concern that <a href="/facts/Protestantism/NXja4K3g">Protestant</a> researchers might use their access to slander or embarrass the Church. Hergenröther's approach led to Pope Leo ordering a reading room constructed for researchers; it opened on 1 January 1881.<a class="footnote-ref" id="fnref:28" href="#fn:28">28</a> When the German Protestant historian <a href="/facts/Theodor_von_Sickel/ossygSxH">Theodor von Sickel</a>, in April 1883, published the results of his research in the archive, which defended the Church against charges of forgery,<a class="footnote-ref" id="fnref:29" href="#fn:29">29</a> Pope Leo was further persuaded. In August 1883 he wrote to the three cardinals who shared responsibility for the archives and praised the potential of historical research to clarify the role of the papacy in European culture and Italian politics. He announced that the archives would be open to research that was impartial and critical. In an address to the <a href="/facts/G%25C3%25B6rres_Society/GQdRUlf5">Görres Society</a> in February 1884, Pope Leo said: "Go to the sources. That is why I have opened the archives to you. We are not afraid of people publishing documents out of them."<a class="footnote-ref" id="fnref:30" href="#fn:30">30</a><a class="footnote-ref" id="fnref:31" href="#fn:31">31</a>

<h3>Access in the modern era</h3>
In 1979, historian <a href="/facts/Carlo_Ginzburg/jYUPR5XX">Carlo Ginzburg</a> sent a letter to the newly elected <a href="/facts/Pope_John_Paul_II/Md3PoDuj">Pope John Paul II</a>, asking that the <a href="/facts/Archives_of_the_Congregation_for_the_Doctrine_of_the_Faith/Ixsb1mCm">archives of the Holy Office</a> (the <a href="/facts/Roman_Inquisition/0t88ge7R">Roman Inquisition</a>) be opened. <a href="/facts/Pope_Benedict_XVI/Kwqu9TB5">Pope Benedict XVI</a> said that letter was instrumental in the Vatican's decision to open those archives.<a class="footnote-ref" id="fnref:32" href="#fn:32">32</a>
Though the archive has developed policies that restrict access to material by pontificate, with access granted no earlier than 75 years after the close of a pope's reign, popes have granted exceptions. For example, Pope Paul VI made the records of the <a href="/facts/Second_Vatican_Council/pH00YMc3">Second Vatican Council</a> available not long after it ended. In 2002, <a href="/facts/Pope_John_Paul_II/Md3PoDuj">Pope John Paul II</a> allowed scholars access to documents from the historical archives of the <a href="/facts/Secretariat_of_State_(Vatican)/rRwWbBCG">Secretariat of State</a> (Second Section) pertaining to the Holy See's relations with Germany during the pontificate of <a href="/facts/Pope_Pius_XI/qQmoRXh1">Pope Pius XI</a> (1922–1939) in order "to put an end to unjust and thoughtless speculation" about the Church's relationship with the <a href="/facts/Nazi_Party/qQCramHd">Nazi Party</a>.<a class="footnote-ref" id="fnref:33" href="#fn:33">33</a>
Following the success of the controversial 2008 film <a href="/facts/Angels_%2526_Demons_(film)/ItJETQdc">Angels & Demons</a>, adapted from the <a href="/facts/Dan_Brown/Y29ftz8h">Dan Brown</a> <a href="/facts/Angels_%2526_Demons/rFmA3m1x">novel of the same name</a>, which depicts a visit to the Archives, the Vatican opened the Archives to a select group of journalists in 2010 to dispute the film's treatment.<a class="footnote-ref" id="fnref:34" href="#fn:34">34</a>
In 2018, <a href="/facts/Pope_Francis/F2uNhKC9">Pope Francis</a> ordered the Vatican Archive to open documents which would assist in a "thorough study" concerning former Cardinal <a href="/facts/Theodore_McCarrick/nSbjF6U9">Theodore McCarrick</a>, who was accused of sexually molesting seminarians and having affairs with young priests.<a class="footnote-ref" id="fnref:35" href="#fn:35">35</a><a class="footnote-ref" id="fnref:36" href="#fn:36">36</a>

<h3>Archives of Pope Pius XII (2020)</h3>
<a href="/facts/Pope_Francis/F2uNhKC9">Pope Francis</a> announced on 4 March 2019 that materials relating to <a href="/facts/Pope_Pius_XII/k2XgCEy2">Pope Pius XII</a> would be opened on 2 March 2020, stating that Pius' legacy had been "debated and even criticized (one might say with some prejudice or exaggeration)", that "The Church is not afraid of history", and that he anticipated "appropriate criticism".<a class="footnote-ref" id="fnref:37" href="#fn:37">37</a><a class="footnote-ref" id="fnref:38" href="#fn:38">38</a> In addition to assessing Pius' response to the <a href="/facts/Holocaust/vGQsAb2y">Holocaust</a>, the archives of the papacy of Pope Pius XII should point to a much broader shift in global Christianity from Europe to the global South.<a class="footnote-ref" id="fnref:39" href="#fn:39">39</a> Since 2006, members of the archives department have been organising the estimated 16 million pages of documents in order to prepare them for viewing by researchers.<a class="footnote-ref" id="fnref:40" href="#fn:40">40</a>

<h2 id="holdings">Holdings</h2>
The Vatican Apostolic Archive has been estimated to contain 85 kilometres (53 mi) of shelving, with 35,000 volumes in the selective catalogue alone.<a class="footnote-ref" id="fnref:41" href="#fn:41">41</a>
Complete archives of letters written by the popes, known as the papal registers, are available beginning with the papacy of <a href="/facts/Pope_Innocent_III/GrWh740f">Pope Innocent III</a> (r. 1198–1216). A few registers of earlier popes also survive, including <a href="/facts/Pope_John_VIII/dVkKxxEh">Pope John VIII</a> (r. 872–882) and <a href="/facts/Pope_Gregory_VII/67umWBjf">Pope Gregory VII</a> (r. 1073–1085).<a class="footnote-ref" id="fnref:42" href="#fn:42">42</a>
Notable documents include <a href="/facts/Henry_VIII_of_England/LFgGAjh0">Henry VIII of England</a>'s request for a marriage annulment, a handwritten transcript of the trial of <a href="/facts/Galileo_Galilei/98VT2z3v">Galileo</a> for heresy, and letters from <a href="/facts/Michelangelo/uKw8rLk4">Michelangelo</a> complaining he had not been paid for work on the Sistine Chapel.<a class="footnote-ref" id="fnref:43" href="#fn:43">43</a>
To mark the 400th anniversary of the Vatican Archives, 100 documents dating from the 8th to the 20th century were put on display from February to September 2012 in the "Lux in arcana – The Vatican Secret Archives reveals itself" exhibition held at the <a href="/facts/Capitoline_Museums/CM3ES5NC">Capitoline Museums</a> in Rome. They included the 1521 <a href="/facts/Papal_bull/rddm96cW">papal bull</a> of excommunication of <a href="/facts/Martin_Luther/7nwEeL0L">Martin Luther</a> and a letter from <a href="/facts/Mary%2c_Queen_of_Scots/QxuRFDb5">Mary, Queen of Scots</a>, written while awaiting her execution.<a class="footnote-ref" id="fnref:44" href="#fn:44">44</a>
The archive also supports its own photographic and conservation studios.<a class="footnote-ref" id="fnref:45" href="#fn:45">45</a>

<h2 id="access-policy">Access policy</h2>

The entrance to the Archive, adjacent to the <a href="/facts/Vatican_Library/RNwpW2hl">Vatican Library</a>, is through the Porta di Santa Anna in via di Porta Angelica (<a href="/facts/Rione/0y1jGJ13">Rione</a> of <a href="/facts/Borgo_(rione_of_Rome)/7PxrqGxP">Borgo</a>). In 1980, following modern renovations, new underground storage space was added. <a class="footnote-ref" id="fnref:46" href="#fn:46">46</a>

<ul><li>Distinguished and qualified scholars from institutions of higher education pursuing scientific research with an adequate knowledge of archival research may apply for an entry card.</li>
<li>Select scholars need an introductory letter from either a recognized institute of research or a suitably qualified person in their field of historical research.</li>
<li>Applicants need to provide their personal data (name, address, etc.), as well as the purpose of their research.</li>
<li>Only paper, pencil and computer laptops are permitted. No ink, pens, or any digital camera photography are allowed inside.</li>
<li>Only five requested articles can be taken at a time, and only sixty <a href="/facts/Academician/E6Sywhsa">academicians</a> per day are allowed inside.<a class="footnote-ref" id="fnref:47" href="#fn:47">47</a></li></ul>
With limited exceptions, materials dated after 1939 were unavailable to researchers until 2 March 2020, when material from the tenure of <a href="/facts/Pope_Pius_XII/k2XgCEy2">Pope Pius XII</a> (1939–1958) was opened for public access. 
An entire section of the distinguished archives relating to the personal affairs of Cardinalship from 1922 onwards cannot be accessed.<a class="footnote-ref" id="fnref:48" href="#fn:48">48</a><a class="footnote-ref" id="fnref:49" href="#fn:49">49</a><a class="footnote-ref" id="fnref:50" href="#fn:50">50</a>

<h2 id="digitization-project">Digitization project</h2>
Main article: <a href="/facts/In_Codice_Ratio/rXEPMlU6">In Codice Ratio</a>

Early in the 21st century, the Vatican Apostolic Archives began an in-house digitization project, to attempt to both make the documents more available to researchers and to help to preserve aging physical documents.<a class="footnote-ref" id="fnref:51" href="#fn:51">51</a> 
As of 2018, the archive had 180 terabytes of digital storage capacity, and had digitized over seven million images.<a class="footnote-ref" id="fnref:52" href="#fn:52">52</a>

<h3>In Codice Ratio</h3>
In 2017, a project based in <a href="/facts/Roma_Tre_University/EBYTDSSx">Roma Tre University</a> called <a href="/facts/In_Codice_Ratio/rXEPMlU6">In Codice Ratio</a> began using artificial intelligence and <a href="/facts/Optical_character_recognition/kdTyxa1l">optical character recognition</a> to attempt to transcribe more documents from the archives.<a class="footnote-ref" id="fnref:53" href="#fn:53">53</a><a class="footnote-ref" id="fnref:54" href="#fn:54">54</a> While character-recognition software is adept at reading typed text, the cramped and many-serifed style of medieval handwriting makes distinguishing individual characters difficult for the software.<a class="footnote-ref" id="fnref:55" href="#fn:55">55</a> Many individual letters of the alphabet are often confused by human readers of medieval handwriting, let alone a computer program. The team behind In Codice Ratio tried to solve this problem by developing a machine-learning software that could parse this handwriting. Their program eventually achieved 96% accuracy in parsing this type of text.<a class="footnote-ref" id="fnref:56" href="#fn:56">56</a>

<h2 id="other-archives-of-the-holy-see">Other archives of the Holy See</h2>
There are other Holy See archives in Rome, since each department of the <a href="/facts/Roman_Curia/LJ7r0uay">Roman Curia</a> has its own archives. The word "secret" in its modern sense can be applied to some of the material kept by the <a href="/facts/Apostolic_Penitentiary/xTPENr8e">Apostolic Penitentiary</a>, when it concerns matters of the <a href="/facts/Internal_and_external_forum_(Catholic_canon_law)/X1MbrnGj">internal forum</a>; but registers of the rescripts that it issued up to 1564 have been deposited in the Vatican Apostolic Archives and are open for consultation by qualified scholars. Half of these have already been put in digital form for easier consultation. The confidentiality of the material means that, in spite of the centuries that have passed since 1564, special rules apply to its publication.<a class="footnote-ref" id="fnref:57" href="#fn:57">57</a>
