Curator's Choice: In his own words... David Prior, of the Parliamentary Archives, on a petition from the people of Manchester in support of the Foreign Slave Trade Abolition Bill, of May 14 1806.
"The Manchester Slave Trade Petition from 1806 is my favourite item from the Archives.
The reason I feel attached to that is because it inspired us way back in 2007 to interpret it and finding out more about the people who had signed it.
It opened our eyes to the power of archival material and the ways you can engage with people.
It's five and a half metres long and has got 2,500 names on it. On the anniversary of the Slave Trade Abolition Act, we asked the Manchester Family History Society if they would like to transcribe the petition.
They did, but they brought more to it than that – through the use of trade directories and some basic family history resources, they were actually able to start identifying the people whose names are on that petition.
That was really interesting. It meant that the moment we stuck it on the web and asked people to look at it, we got people who had done family history research finding their ancestors on it.
You really felt people were making a connection and being genuinely, emotionally moved by this document – and they really were. That's why it means quite a lot to us."
