Aliement support does not have a single inventor. This legal institution has been developing for centuries in different cultures and states. The earliest written mentions of the obligation to support a former spouse and children are found in the laws of the Babylonian king Hammurabi, dating back to approximately 1750 BC. In Ancient Rome, alimony obligations were also formalized, but they primarily concerned divorced wives, not children. Roman law paid much less attention to the support of offspring than modern legislation. In medieval Europe, the Christian church had a significant influence on the development of alimony norms. Canon law prescribed that husbands should support former spouses, which strengthened this practice in the European legal tradition. Interestingly, in the late 1st century AD under the Roman Emperor Nerva, there was a state program called \"alimenta.\" However, it was not modern alimony from parents, but rather social assistance to poor orphans from the state treasury — an equivalent of today's child allowances. The modern understanding of alimony as the obligation of parents to support minor children formed in the 19th-20th centuries during the development of family law in European countries and Russia. This principle was enshrined in the legislation of all civilized states and today is a universal norm. Thus, alimony is not the invention of a single person, but the result of a multi-century evolution of legal consciousness, religious prescriptions, and state policy in the field of protecting the family and childhood.
