The states of the German Confederation were those member states that from 20 June 1815 were part of the German Confederation, which lasted, with some changes in the member states, until 24 August 1866, under the presidency of the Austrian imperial House of Habsburg, which was represented by an Austrian presidential envoy to the Federal diet in Frankfurt.
The German Confederation was an association of 39 German-speaking states in Central Europe, created by the Congress of Vienna in 1815 to coordinate the economies of separate German-speaking countries and to replace the former Holy Roman Empire, which had been dissolved in 1806. The German Confederation excluded German-speaking lands in the eastern portion of the Kingdom of Prussia, the German cantons of Switzerland, and Alsace within France which was majority German speaking.
The House of Habsburg, also called the House of Austria, was one of the most influential and distinguished royal houses of Europe. The throne of the Holy Roman Empire was continuously occupied by the Habsburgs from 1438 until their extinction in the male line in 1740. The house also produced emperors and kings of the Kingdom of Bohemia, Kingdom of England, Kingdom of Germany, Kingdom of Hungary, Kingdom of Croatia, Kingdom of Illyria, Second Mexican Empire, Kingdom of Ireland, Kingdom of Portugal, and Kingdom of Spain, as well as rulers of several Dutch and Italian principalities. From the 16th century, following the reign of Charles V, the dynasty was split between its Austrian and Spanish branches. Although they ruled distinct territories, they nevertheless maintained close relations and frequently intermarried.
In politics, a diet is a formal deliberative assembly. The term is mainly used historically for the Imperial Diet, the general assembly of the Imperial Estates of the Holy Roman Empire, and for the legislative bodies of certain countries. Modern usage mainly relates to the Kokkai of Japan, called "Diet" in English, or the German Bundestag, the Federal Diet.
On the whole, its territory nearly coincided with that remaining in the Holy Roman Empire at the outbreak of the French Revolution, with the notable exception of Belgium. Except for the two rival major powers, Austria and Prussia, and the western left bank of the Rhine (which France had annexed, with tiny Katzenelnbogen), the other member states or their precursors, making up most of present Germany, had been within Napoleon's Confederation of the Rhine.
The Holy Roman Empire was a multi-ethnic complex of territories in Western and Central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806 during the Napoleonic Wars. The largest territory of the empire after 962 was the Kingdom of Germany, though it also came to include the neighboring Kingdom of Bohemia, the Kingdom of Burgundy, the Kingdom of Italy, and numerous other territories.
The French Revolution was a period of far-reaching social and political upheaval in France and its colonies beginning in 1789. The Revolution overthrew the monarchy, established a republic, catalyzed violent periods of political turmoil, and finally culminated in a dictatorship under Napoleon who brought many of its principles to areas he conquered in Western Europe and beyond. Inspired by liberal and radical ideas, the Revolution profoundly altered the course of modern history, triggering the global decline of absolute monarchies while replacing them with republics and liberal democracies. Through the Revolutionary Wars, it unleashed a wave of global conflicts that extended from the Caribbean to the Middle East. Historians widely regard the Revolution as one of the most important events in human history.
The Austrian Empire was a Central European multinational great power from 1804 to 1867, created by proclamation out of the realms of the Habsburgs. During its existence, it was the third most populous empire after the Russian Empire and the United Kingdom in Europe. Along with Prussia, it was one of the two major powers of the German Confederation. Geographically, it was the third largest empire in Europe after the Russian Empire and the First French Empire. Proclaimed in response to the First French Empire, it partially overlapped with the Holy Roman Empire until the latter's dissolution in 1806.
The four free cities were republics by constitution, while all the others were monarchies, some constitutional and some absolutist.
A republic is a form of government in which the country is considered a “public matter”, not the private concern or property of the rulers. The primary positions of power within a republic are not inherited, but are attained through democracy, oligarchy or autocracy. It is a form of government under which the head of state is not a hereditary monarch.
A constitutional monarchy is a form of monarchy in which the sovereign exercises authority in accordance with a written or unwritten constitution. Constitutional monarchy differs from absolute monarchy in that constitutional monarchs are bound to exercise their powers and authorities within the limits prescribed within an established legal framework. Constitutional monarchies range from countries such as Morocco, where the constitution grants substantial discretionary powers to the sovereign, to countries such as Japan and Sweden where the monarch retains no formal authorities.
Absolute monarchy is a form of monarchy in which the monarch holds supreme authority and where that authority is not restricted by any written laws, legislature, or customs. These are often hereditary monarchies. In contrast, in constitutional monarchies, the head of state's authority derives from and is legally bounded or restricted by a constitution or legislature.
