1. Why use this guide?

Use this guide to find sources for English foreign policy and diplomatic issues before 1509.

2. Essential information

In medieval England no single official or institution had overall responsibility for foreign affairs. There was no Foreign Office.

Responsibilities were shared by:

  • the Royal Council, which discussed foreign affairs and formulated England’s policy in consultation with the king
  • Chancery, which dealt with the administration of treaties and letters
  • the Exchequer, which dealt with the financial aspects of diplomacy

Diplomatic missions were frequently undertaken by:

  • the great officers of state
  • leading churchmen
  • major noblemen
  • the king’s personal friends and trusted servants of lower rank

Very early documentation of the conduct of diplomacy consists of chronicles and various fragments from early Anglo-Norman times, most of which is not held by The National Archives.

These are kept among former collections of antiquarians at institutions such as:

Many original English diplomatic documents are now in the archival collections of the countries with which the medieval crown negotiated.

We hold:

  • accounts (for the expenses of envoys )
  • diplomatic correspondence (scattered in a number of record series or enrolled in the records of Chancery and the artificial Special Collections)
  • documents relating to the royal council

There was little differentiation between foreign and domestic affairs in the management of government business. As a result, documents relating to English external policy are found in a mixture of record series.

These documents were usually written in Latin or French using medieval abbreviations.

Diplomatic sources  become much fuller after the start of the Chancery enrolments in 1199.

3. General search tips

Begin by consulting published sources.

Published information about some of the documents, including full transcripts of original texts, is in:

You can browse record series in our catalogue mentioned throughout this guide and identify relevant document references:

  • date
  • record descriptions in our catalogue (though these may be limited)

For some record series  you can use calendars which summarise the text of original documents. You may also wish to use calendars to access the original records.

4. Chancery enrolments

4.1 What are the main record series of chancery enrolments?

The main record series  of Chancery enrolments are listed below. Click on the links to find out more about each record series:

  • C 54 – Close Rolls, including letters of credence to foreign rulers
  • C 61 – Gascon Rolls, which include treaties, truces and appointments of ambassadors in French lands under English rule
  • C 66 – Patent Rolls, from 1201, including letters of safe conduct, protection, the appointments and powers of ambassadors, and negotiations and general correspondence
  • C 67 – Patent Rolls, Supplementary, 1275-1749
  • C 76 – Treaty rolls, which includes enrolments of treaties, letters and other diplomatic material, 1234-1675. Many of them concern the administration of England’s territory in France, but diplomatic correspondence with the Holy Roman Empire and other states is also present. Treaties could also be enrolled on the other rolls mentioned above
  • C 64 – Norman Rolls, including diplomatic letters patent, writs and treaties between English kings as dukes of Normandy and the dukes of Brittany and Burgundy

5. Other Chancery documents

5.1 Chancery Miscellanea (C 47)

Browse C 47, Chancery Miscellanea, which includes foreign documents many of which are letters, petitions or warrants and a number of documents which are not described in published sources.

Note that:

  • bundles 22-23 Scottish documents, including homage rolls
  • bundles 24-26 concern French possessions of the English kings
  • bundles 27-32 are the main sequence of diplomatic documents

Much diplomatic correspondence was issued under the privy or secret seals in an effort to control the dissemination of instructions, reports and other information. Correspondence issued in this way was intended only for the named individuals or officers to whom it was addressed and not for wider public scrutiny.

Consult also SC 1 which contains ancient chancery and exchequer records. See section on Special collections for further guidance.

5.2 Chancery Warrants (C 81 and PSO 1)

Warrants were the accepted means of issuing authenticated instructions from the king or royal council to representatives of the crown engaged on particular diplomatic or other official activity.

Read the catalogue descriptions in C 81 and PSO 1 for more information about these records.

9. Using the calendars to access the original records

Calendars cover specific date periods for particular record types (patent or close rolls in C 66 or C 54 respectively). Use the calendar alongside our catalogue to identify the original manuscript it refers to.

9.1 How do I locate The National Archives’ document references from the calendar entries?

You can cross-reference an entry in the calendar with our catalogue to locate a full document reference to the original manuscript it refers to.

If you are looking at rolls, each roll normally relates to a regnal year and the corresponding calendar summary presents the entries on the front and back of the relevant rolls in the sequence they are found in the manuscript.

The regnal year is recorded at the top of each page of the calendar as a running entry until the subject roll changes.

Look for the entries for a single regnal year which might be broken down into several parts – in the format ‘1 Henry IV, part 1’.This is the key information, since it can be converted using our catalogue.

Browse the series in question within our catalogue to locate the year referenced in the calendar.

If you are looking at the Calendar of Patent Rolls, Henry IV, vol 1, 1399-1401, this volume contains the text of the rolls for 1-2 Henry IV.

Those manuscript rolls are C 66/354-365, but we can see on our catalogue that the patent roll for 1 Henry IV part 1 is C 66/354.

When the text at the top of the calendar changes to 1 Henry IV part 2 we know that the entries in C 66/355 are now being summarised in the calendar.

Note that:

  • some of the calendars provide summaries of their contents in English
  • depending on the date, the publisher and the type of document being summarised, the other entries will be in Latin and French. This is especially the case with calendars published before 1939
  • where all HMSO calendars produce extended transcripts of the original text this is not normally translated into English
