English common law, for instance, did not permit adoption since it contradicted the customary rules of inheritance. In the same vein, Frances Napoleonic Code made adoption difficult, requiring adopters to be over the age of 50, sterile, older than the adopted person by at least 15 years, and to have fostered the adoptee for at least six years. Some adoptions continued to occur, however, but became informal, based on ad hoc contracts. For example, in the year 737, in a charter from the town of Lucca, three adoptees were made heirs to an estate. Like other contemporary arrangements, the agreement stressed the responsibility of the adopted rather than adopter, focusing on the fact that, under the contract, the adoptive father was meant to be cared for in his old age; an idea that is similar to the conceptions of adoption under Roman law.Europes cultural makeover marked a period of significant innovation for adoption. Without support from the nobility, the practice gradually shifted toward abandoned children. Abandonment levels rose with the fall of the empire and many of the foundlings were left on the doorstep of the Church. Initially, the clergy reacted by drafting rules to govern the exposing, selling, and rearing of abandoned children. The Churchs innovation, however, was the practice of oblation, whereby children were dedicated to lay life within monastic institutions and reared within a monastery. This created the first system in European history in which abandoned children did not have legal, social, or moral disadvantages.
More recently the military dictatorship in Argentina from 1976 to 1983 is known to have given hundreds of babies born to women captives who were then murdered to be brought up by military families.In Spain under Francisco Francos 1939–75 dictatorship the newborns of some left-wing opponents of the regime, or unmarried or poor couples, were removed from their mothers and adopted. New mothers were frequently told their babies had died suddenly after birth and the hospital had taken care of their burials, when in fact they were given or sold to another family. It is believed that up to 300,000 babies were involved. These system—which allegedly involved doctors, nurses, nuns and priests—outlived Francos death in 1975 and carried on as an illegal baby trafficking network until 1987 when a new law regulating adoption was introduced.On January 29, 2010, a group of ten American Baptist missionaries from Idaho attempted to cross the Haiti–Dominican Republic border with 33 Haitian children. The group, known as the New Life Childrens Refuge, did not have proper authorization for transporting the children and were arrested on kidnapping charges. After the process for the adoption of 400 children by families in the US and the Netherlands was expedited, Unicef and SOS Children urged an immediate halt to adoptions from Haiti.
