A movement called Chartism grew demanding the right to vote for everyone in free and fair elections. As the great famine hit Ireland and millions migrated to the United States, Chartists staged a mass march from Kennington Common to Parliament in 1848 as revolutions broke out across Europe, and the "Communist Manifesto" was drafted by German revolutionary Karl Marx and Manchester factory owner Friedrich Engels. While the Crimean War distracted from social reform and Viscount Palmerston opposed anything, the American civil war of 1860 to 1865 ended slavery in the US, and the UK gradually enabled greater political freedom. In the Second Reform Act 1867 more middle class property owners were enfranchised, the Elementary Education Act 1870 provided free primary school, and the Trade Union Act 1871 enabled free association without criminal penalty. William Ewart Gladstone's UK Midlothian campaign between 1878-80 began the move towards modern political campaigning. The Representation of the People Act 1884 reduced the property qualification further, so that around one third of men could vote.
