Christiansborg Palace is a palace and government building on the islet of Slotsholmen in central Copenhagen, Denmark. It is the seat of the Danish Parliament, the Danish Prime Minister's Office, and the Supreme Court of Denmark. Also, several parts of the palace are used by the Danish monarch, including the Royal Reception Rooms, the Palace Chapel and the Royal Stables.

The prime minister of Denmark is the head of government in the Kingdom of Denmark comprising the three constituent countries: Denmark, Greenland and the Faroe Islands. Before the creation of the modern office, the kingdom did not initially have a head of government separate from its head of state, namely the monarch, in whom the executive authority was vested. The Constitution of 1849 established a constitutional monarchy by limiting the powers of the monarch and creating the office of premierminister. The inaugural holder of the office was Adam Wilhelm Moltke.
