"The Prize Papers of the High Court of Admiralty are both unique and fascinating: a huge collection of documents and small objects from the period between 1652 and1815, which is being held by the National Archives of the UK. The Prize Papers are a result of an early modern warfare practice which witnessed its heyday in the context of 17th and 18th century European colonial expansion. During wartime, hostile European powers would capture their enemies‘ ships all over the world, dealing severe blows to their military, political and economic force."
"Soon, you will be able to go past this point and access the Prize Papers Portal, where you will have the opportunity to discover a constantly growing number of Prize Papers documents and objects. It will be possible to browse according to
captures
ships
subjects
types of documents
or by way of a random document leading the way into the collection."
