Duchy of Saxe-Meiningen
After the death of Caroline's husband in 1745 she ruled as regent for her minor son Charles Frederick Ernest. In a decree of 1746, she took measures against the "wandering gypsies and begging people", in which even the death penalty was possible. She restructured the Code of Criminal Procedure and banned the sale of a fief, allodial title or real estate without authorization by the sovereign. In a case before the High Court in which the Duchy of Saxe-Meiningen demanded the district of Sonnefeld, which lasted from 1743 to 1752, she was represented by the secret Privy Councillor Johann Sebastian Kobe von Koppenfels, who helped her win the case.
