 Thus in 1824, the King of Prussia turned to the childless Emperor Alexander I of Russia to adopt Elisa, but the Russian ruler declined.The second adoption plan by Elisa's uncle, Prince Augustus of Prussia, likewise failed as the responsible committee considered that adoption "does not alter the blood" (a principle which governs noble and royal connections to the present day).Another factor was the influence of the Mecklenburgish kinsmen of the deceased Queen Louise in the German and Russian courts who were not fond of Elisa's father and opposed the possible marriage.
