The North German Confederation (German: "Norddeutscher Bund" ) was the German federal state which existed from July 1867 to December 1870.
 Some historians also use the name for the alliance of 22 German states formed on 18 August 1866 ("Augustbündnis ").
 In 1870–1871, the south German states of Baden, Hesse-Darmstadt, Württemberg and Bavaria joined the country.
 On 1 January 1871, the country received a new constitution that gave it the name "German Empire" but largely remained the same, which is why the North German Confederation continues as the German nation state which still exists today.

 The survey is funded by the German Federal Government and the State of Berlin via the «Bund-Länder-Kommission» (State/Federal State Commission) for Educational Planning and Research Promotion.
The term Lesser Germany (German: "Kleindeutschland", in opposition to 'Greater Germany') relates essentially to Germany without Austria.
 In the 19th century, a part of the Austrian Empire belonged to the German Confederation.
 In the revolutionary era of 1848-1850, it was discussed whether Austria or a part of Austria could belong to a new German federal state.
 In 1867-1871, the 'Lesser Germany' became reality: a federal state under leadership of Prussia and without Austria.
 After that, the term lost its significance because since then 'Germany' is usually identified as this Lesser Germany.

The Constitution of the German Confederation (German: "Verfassung des Deutschen Bundes", or "Novemberverfassung") was the constitution of the German federal state at the beginning of the year 1871.

Federal prince (German: "Bundesfürsten" , "Princes of the Federation") was the generic term for the royal heads of state (monarchs) of the various states making up the German Empire, with the exception of the states that were republics and Alsace-Lorraine which had a special status.
 The empire was a federal state, with its constituent states remaining sovereign states.
 Among the states, the majority were monarchies, 3 states were republics and Alsace-Lorraine was an imperial territory ruled by a steward.
 The states became part of the German Empire by an 1871 treaty.
 The head of the empire was granted the title German Emperor (with the title "Emperor of Germany" being deliberately avoided), and was simultaneously a federal prince as King of Prussia, the sovereign of its largest federal state.
 Of the princely heads of state, 4 held the title King (König) (the Kings of Prussia, Bavaria, Saxony, and Württemberg), 6 held the title Grand Duke (Großherzog), 5 held the title Duke (Herzog), and 7 held the title Prince (i.e. Sovereign Prince, "Fürst").
 The heads of state of the city republics, where the concepts of nobility and royalty did not exist, were of equal standing to the federal princes and held the titles First Mayor and President of the Senate (Hamburg), Mayor and President of the Senate (Lübeck), and President of the Senate and Mayor (Bremen).
 The heads of state of the city republics were regarded as primi inter pares among the senators according to the states' republican constitutions, and these states were ruled by an oligarchy of hereditary Grand Burghers, also known as Hanseaten or patricians.
