These developmental differences seem to occur in the way young adoptive parents deal with major life events. In the event of parental divorce, adoptive parents behaved differently from children who were not adopted. While after the parents` divorce, the general population experienced more behavioural problems, substance use, reduced academic performance and limited social skills, the adoptive population did not appear to be affected by their external relationships, particularly in their school or social capacities.  In Spain, under the dictatorship of Francisco Franco in 1939-1975, the newborns of some opponents of the leftist regime or of single or poor couples were abducted and adopted by their mothers. New mothers were often informed that their babies had died suddenly after birth and that the hospital was attending their funerals when they were actually being given or sold to another family. Up to 300,000 babies are believed to have been involved. This system – which reportedly involved doctors, nurses, nuns and priests – survived Franco`s death in 1975 and continued as an illegal child trafficking ring until the introduction of a new adoption law in 1987.   Until 1979, representatives of 32 organizations from 33 states, Canada and Mexico in Washington, DC, to establish the American Adoption Congress (AAC), which unanimously adopts a resolution: “Open Records complete with all credentials for all members of the adopted country, birth parents, adoptive parents and adoptive parents at the age of the majority of the adoptive child (18 or 19 years old , depending on the state) or earlier, if all members of the trio agree.  Subsequent years saw the development of militant organizations such as The Bastard Nation (founded in 1996), groups that helped break record-breaking records in Alabama, Delaware, New Hampshire, Oregon, Tennessee and Maine. In 2019, a coalition of New York and national adoption advocates worked successfully to overturn an 83-year-old restrictive law, and New York-born adult adoptive parents and their descendants now have the right to apply for and receive their own original birth certificates.   Starting in 2020, 10 U.S. states will recognize the right of adopted adults to obtain their own birth certificates, including Alabama, Alaska, Colorado, Hawaii, Kansas, Maine, New Hampshire, New York, Oregon and Rhode Island.   This system of informal learning and adoption extended to the 19th century, now considered a transitional period in the history of adoption. Under the leadership of social activists, orphans began to promote adoptions based on mood rather than work; The children were placed under child care arrangements as family members rather than apprenticeships.  The growth of this model is believed to have contributed to the adoption of the first modern massachusetts Commonwealth adoption law in 1851, which is unique in that it codified the ideal of the “best interests of the child.”   Despite its intent, the system operated in practice in the same way as previous incarnations.
