The London Peace Society, under the initiative of Elihu Burritt and Henry Richard, convened the first International Peace Congress in London in 1843.[8] The congress decided on two aims: the ideal of peaceable arbitration in the affairs of nations and the creation of an international institution to achieve that. Richard became the secretary of the Peace Society in 1850 on a full-time basis, a position which he would keep for the next 40 years, earning himself a reputation as the 'Apostle of Peace'. He helped secure one of the earliest victories for the peace movement by securing a commitment from the Great Powers in the Treaty of Paris (1856) at the end of the Crimean War, in favour of arbitration.
