I want to make a backstory with a more reactionary Britain. One where the British government drags its feet or is piecemeal in regards to things like the Corn Laws, the Reform Act of 1832, the abolition of slavery, Catholic emancipation, and the Colonial Laws Validity Act of 1865. I'd also like to get the most 'German' and actively reactionary monarch on the throne possible. Not only maximum delaying tactics but also increased militarism and hawkishness towards powers like the US.
How could this happen and what would be the effects of it?
This is a lead up to the Chartist movement becoming militant and a revolution in Britain, but I want to explore the effects on the Empire and world before something like that could happen.
