Welfare is the provision of a minimal level of well-being and social support for citizens without current means to support basic needs. In most developed countries, welfare is largely provided by the government from tax income, and to a lesser extent by charities, informal social groups, religious groups, and inter-governmental organizations.
The welfare state expands on this concept to include services such as universal healthcare and unemployment insurance.
In the Roman Empire, the first emperor Augustus provided the Cura Annonae or grain dole for citizens who could not afford to buy food every month. Social welfare was enlarged by the Emperor Trajan. Trajan's program brought acclaim from many, including Pliny the Younger. The Song dynasty government (c.1000AD in China) supported multiple programs which could be classified as social welfare, including the establishment of retirement homes, public clinics, and paupers' graveyards. According to economist Robert Henry Nelson, "The medieval Roman Catholic Church operated a far-reaching and comprehensive welfare system for the poor..."
Early welfare programs in Europe included the English Poor Law of 1601, which gave parishes the responsibility for providing welfare payments to the poor. This system was substantially modified by the 19th-century Poor Law Amendment Act, which introduced the system of workhouses.
