Women's suffrage event in response to parliamentary proceedings regarding the Conciliation Bill, which would have extended the right of women to vote to around 1,000,000 wealthy, property-owning women. The bill made it to a second reading, but Asquith indicated that there would be no more Parliamentary time for the reading in the current session.
In response, the WSPU sent a delegation of around 300 women to protest, and 200 were assaulted when they attempted to run past the police. Many of the arrested suffragettes reported being assaulted and manhandled by the police. It was the first documented use of police force against suffragettes. In the aftermath, Asquith's car was vandalized, and the event caused some embarrassment to Winston Churchill who was Home Secretary at the time.
The events of Black Friday were a public relations disaster for the government; the press took the side of the Suffragettes, printing pictures of police assaulting unarmed female protesters. The actions of the police were greatly criticised. After Black Friday, Asquith stated that if the Liberals were elected at the next general election, they would include a Suffrage Bill that could be amended to allow women to vote. The WSPU rejected this, believing that it was an attempt to delay reform; the events of Black Friday were damaging to the suffrage campaign as well, as they caused MPs to distance themselves from the issue.
One woman who had been badly treated by the police and was arrested for stone throwing a few days earlier, later died after being released from prison on Christmas Day 1910 - she was Emmeline Pankhurst’s sister, Mary Clarke.
