In 1913, there was a private members bill read to the House of Commons by the Scottish Liberal MP, Henry Cowan. It reached the stage of a second reading in early 1914, the First World War extinguished any chance of it being passed. Scotland would not get devolution until the 1990s.
So what if, Henry Cowan's Home Rule Bill had managed to produce a Scottish Parliament before the First World War derailed it? How would Scotland be different today?
