1815-1870

From a library sale I picked up 50p copy of The Age of Reform 1815-1870 (originally written 1938; though mine is the 2nd ed from 1962) by Sir Llewellyn 'crikey what a name' Woodward. History of another era from another era:

Irish immigration increased the number of Roman Catholics, but most of these immigrants were very poor people whose troubles were economic rather than political. [502]

There's a meaningful distinction! Economics, poverty and politics completely different things!
