Today in 1833 William Wilberforce died. He worked many years to have the British slave trade outlawed, finally seeing success in 1807, and then more years to end slavery itself. He died days after learning that that piece of legislation was sure to succeed.
Of course, Wilberforce did not do this singlehandedly. Frances Rolleston was one of those recruited into the cause in 1826 by "a deputation of influential Quakeresses" because, they told her, the gentlemen would not stir. The anti-slavery people were told that they could do nothing, that Parliament disregarded petitions. But the overwhelming number collected could not be disregarded.
Remember, they did not have the Internet or even the telephone. Every petition signer had to be contacted by letter or in person. In Sheffield alone, Frances reported, the ladies collected 17,000 men's signatures and 24,000 women's.
Each petition held 150 to 200 signatures. Frances was present when all the petitions were combined into one. The movie Amazing Grace (Bristol Bay Productions 2006 and Twentieth Century Fox Home Entertainment 2007) has a climactic scene showing Wilberforce unrolling the combined petitions before Parliament. PG, worth watching.
