Britain renounces any role in the slave trade

March 1807

The campaign to end the slave trade was an early example of a privately-led human rights campaign influencing state conduct. Britain championed the end of the slave trade, incorporating anti-slavery norms in the 1815 Treaty of Paris.

Congress of Vienna

June 1815

Following the turmoil of the Napoleonic Wars, the Great Powers sought an international system that would allow them to maintain peace and international stability. The Congress of Vienna, held from November 1814 to June 1815, called for restoration of governments overthrown in the Revolutionary and Napoleonic Wars since 1792, dynastic legitimacy, and solidarity of the Great Powers. The resulting June Final Act attempted to establish a balance of power amongst the Great Powers, allowing future French aggression to be checked and revolutionary movements to be halted. The Powers utilized regular meetings known as the Concert of Europe to resolve differences and to halt new threats to the European peace.
