Question: what does Aulic Council and Hofburg have in common?
Context: The Hofburg is the former imperial palace in the centre of Vienna, Austria.  Built in the 13th century and expanded in the centuries since, the palace has been the seat of power of the Habsburg dynasty rulers, and today the official residence and workplace of the President of Austria.  It was the principal imperial winter residence, as Schönbrunn Palace was the summer residence. The Austrian Parliament Building (German: "Parlamentsgebäude" , colloquially "das Parlament") in Vienna is where the two houses of the Austrian Parliament conduct their sessions.  The building is located on the "Ringstraße" boulevard in the first district "Innere Stadt", near Hofburg Palace and the Palace of Justice.  It was built to house the two chambers of the Imperial Council ("Reichsrat"), the bicameral legislature of the Cisleithanian (Austrian) part of the Austro-Hungarian Empire.  Since its construction, the Parliament Building has been the seat of these two houses, and their successors—the National Council ("Nationalrat") and the Federal Council ("Bundesrat")—of the Austrian legislature. The Hofkriegsrat (or Aulic War Council, sometimes Imperial War Council) established in 1556 was the central military administrative authority of the Habsburg Monarchy, the predecessor of the Austro-Hungarian Ministry of War.  The agency was directly subordinated to the Habsburg emperors with its seat in Vienna. Prince Franz Seraph of Orsini-Rosenberg (18 October 1761 – 4 August 1832) joined the army of Habsburg Austria and fought against the Ottoman Turks, winning a prestigious award for bravery.  In the 1790s, he served in the wars against the First French Republic and received promotion to general officer.  During the Napoleonic Wars he led a division in 1805 and an army corps in 1809.  He became a member of the Hofkriegsrat (Aulic Council) in 1811.  He was the Proprietor (Inhaber) of an Austrian light cavalry regiment from 1801 until his death. The National Council of Churches in India is the Ecumenical Forum of the Protestant and Orthodox Churches in India.  The Council was established in 1914 as the National Missionary Council.  In 1923, the Council constituted itself as the National Christian Council of India, Burma and Ceylon.  The Councils of Burma and Sri Lanka separated, and in 1979 the Council transformed itself into what is known as the National Council of Churches in India.  It is an Inter-confessional autonomous Council and an ecumenical expression constantly initiating, promoting and coordinating various forms of ministries of Witness and Service in the wider community and society.  The Council also serves as a common platform for thought and action and as such it brings together the Churches and other Christian organisations for mutual consultation, assistance and action in all matters related to the life and witness of the Churches in India.  The NCCI is committed to the Gospel values of Justice, Unity & Peace. Madison Common Council is a city council: the legislative branch of the government of the City of Madison in Wisconsin.

The Reichskammergericht (] , "Imperial Chamber Court"; Latin: "Iudicium imperii" ) was one of two highest judicial institutions in the Holy Roman Empire, the other one being the Aulic Council in Vienna.  It was founded in 1495 by the Imperial Diet in Worms.  All legal proceedings in the Holy Roman Empire could be brought to the Imperial Chamber Court, except if the ruler of the territory had a so-called "privilegium de non appellando", in which case the highest judicial institution was found by the ruler of that territory.  Another exception was criminal law.  The Imperial Chamber Court could only intervene in criminal cases if basic procedural rules had been violated. The Aulic Council (Latin: "Consilium Aulicum" , German: "Reichshofrat" , literally meaning Court Council of the Empire) was one of the two supreme courts of the Holy Roman Empire, the other being the Imperial Chamber Court.  It had not only concurrent jurisdiction with the latter court, but in many cases exclusive jurisdiction, in all feudal processes, and in criminal affairs, over the immediate feudatories of the Emperor and in affairs which concerned the Imperial Government.  The seat of the Aulic Council was at the Hofburg residence of the Habsburg emperors in Vienna. Imperial immediacy (German: "Reichsfreiheit" or "Reichsunmittelbarkeit ") was a privileged constitutional and political status rooted in German feudal law under which the Imperial estates of the Holy Roman Empire such as Imperial cities, prince-bishoprics and secular principalities, and individuals such as the Imperial knights, were declared free from the authority of any local lord and placed under the direct ("immediate") authority of the Emperor, and later of the institutions of the Empire such as the Diet ("Reichstag "), the Imperial Chamber of Justice and the Aulic Council. Karl I of Hohenzollern (1516 in Brussels – 18 March 1576 at Sigmaringen Castle) was Count of County of Hohenzollern from 1525 to 1575.
