1863 CE
Abraham Lincoln signs the Emancipation Proclamation during the third year of the American Civil War, making the abolition of slavery in the Confederate States of America an official war goal. The signing proclaims the freedom of 3.1 million of the nation's four million slaves and immediately frees 50,000 of them, with the rest freed as the Union Army advances. This event marks the start of America's Reconstruction Era. Master Lucius Tar Paint Company (Teerfarbenfabrik Meister Lucius), predecessor of Hoechst as a worldwide chemical manufacturing brand, is founded in a suburb of Frankfurt am Main, Germany. Shortly after his government loses a vote of no-confidence, former premier Alfred Domett moves a resolution in Parliament that the Capital of New Zealand be moved closer to Cook Strait. This leads to the movement of the Capital to Wellington in 1865.
