middle of the 18th century. This emerging upper-class fashion for benevolence resulted in the incorporation of the first charitable organizations. Captain Thomas Coram, appalled by the number of abandoned children living on the streets of London, set up the Foundling Hospital in 1741 to look after these unwanted orphans in Lamb's Conduit Fields, Bloomsbury. This, the first such charity in the world, served as the precedent for incorporated associational charities in general. Jonas Hanway, another notable philanthropist of the Enlightenment era, established The Marine Society in 1756 as the first seafarer's charity, in a bid to aid the recruitment of men to the navy. By 1763 the Society had recruited over 10,000 men; an Act of Parliament incorporated it in 1772. Hanway was also instrumental in establishing the Magdalen Hospital to rehabilitate prostitutes. These organizations were funded by subscription and run as voluntary associations. They raised public awareness of their activities through the emerging popular press and were generally held in high social regard – some charities received state recognition in the form of the royal charter. Charities also began to adopt campaigning roles, where they would champion a cause and lobby the government for legislative change. This included organized campaigns against the ill treatment of animals and children and the campaign that eventually succeeded at the turn of the 19th century in ending the slave trade throughout the British Empire and within its considerable sphere of influence. (This process was however a lengthy one, which finally concluded when Saudi Arabia abolished slavery in 1962.) The Enlightenment also saw growing philosophical debate between those who championed state intervention and those who believed that private charities should provide welfare. The Reverend Thomas Malthus (1766-1834), the political economist, criticized poor relief for paupers on economic and moral grounds and proposed leaving charity entirely to the private sector. His views became very influential and informed the Victorian laissez-faire attitude toward state intervention for the poor. Growth during 19th century During the 19th century a profusion of charitable organizations emerged to alleviate the awful conditions of the working class in the slums. The Labourer's Friend Society, chaired by Lord Shaftesbury in the United Kingdom in 1830, aimed to improve working-class conditions. It promoted, for example, the allotment of land to labourers for "cottage husbandry" that later became the allotment movement. In 1844 it became the first Model Dwellings Company – one of a group
