Career
After the death of Jacob Preuss in December 1826, Adamy was elected as a representative of the group of landowners in the electoral district of Dillenburg in the Second Chamber of the Estates of the Duchy of Nassau. Adamy served in the Second Chamber for four years. In 1832, Adamy relinquished his mandate when he was one of the 15 deputies who boycotted the protest against the Pairsschub of 1831 as part of the 1832 Nassau Domain Dispute.
The Pairsschub was an instrument used by William, Duke of Nassau to increase membership in the First Chamber of the Estates to benefit his government by weakening the Second Chamber.
Joseph Adamy was a Roman Catholic.
