Kaiser in the context of "German Emperor"

Caesar (Latin: [ˈkae̯.sar] English pl. Caesars; Latin pl. Caesares; in Greek: Καῖσαρ Kaîsar) is a title of imperial character. It derives from the cognomen of Julius Caesar. The change from being a surname to a title used by the Roman emperors can be traced to AD 68, following the fall of the Julio-Claudian dynasty. When used on its own, the title denoted heirs apparent, who would later adopt the title Augustus on accession. The title remained an essential part of the style of the emperors, and became the word for "emperor" in some languages, such as German (Kaiser) and Slavic (Tsar).

The Holy Roman Emperor, originally and officially the Emperor of the Romans (Latin: Imperator Romanorum; German: Kaiser der Römer) during the Middle Ages, and also known as the Roman-German Emperor since the early modern period (Latin: Imperator Germanorum; German: Römisch-Deutscher Kaiser), was the ruler and head of state of the Holy Roman Empire. The title was held in conjunction with the title of King of Italy (Rex Italiae) from the 8th to the 16th century, and, almost without interruption, with the title of King of Germany (Rex Teutonicorum, lit. 'King of the Teutons') throughout the 12th to 18th centuries.

The Holy Roman Emperor title provided the highest prestige among medieval Catholic monarchs, because the empire was considered by the Catholic Church to be the only successor of the Roman Empire during the Middle Ages and the early modern period. Thus, in theory and diplomacy, the emperors were considered primus inter pares—first among equals—among other Catholic monarchs across Europe.

The emperor of Austria (German: Kaiser von Österreich, Latin: Imperator Austriae) was the ruler of the Austrian Empire and later the Austro-Hungarian Empire. The hereditary imperial title and office was proclaimed in 1804 by Francis II, Holy Roman Emperor, a member of the House of Habsburg-Lorraine, and continually held by him and his heirs until Charles I relinquished power in 1918.

The emperors retained the title of Archduke of Austria. The wives of the emperors held the title empress, while other members of the family held the titles of archduke or archduchess.

Fürst (German pronunciation: [ˈfʏʁst] , female form Fürstin, plural Fürsten; from Old High German furisto, "the first", a translation of the Latin princeps) is a German word for a ruler as well as a princely title. Fürsten were, starting in the Middle Ages, members of the highest nobility who ruled over states of the Holy Roman Empire and later its former territories, below the ruling Kaiser (emperor) or König (king).

The Wilhelmine period or Wilhelmian era (German: Wilhelminische Zeit, Wilhelminische Epoche) comprises the period of German history between 1888 and 1918, embracing the reign of Kaiser Wilhelm II in the German Empire from the death of Kaiser Friedrich III until the end of World War I and Wilhelm's abdication during the November Revolution.

It represented an era of creative ferment in the society, politics, culture, art, literature, and architecture of Germany. It also roughly coincided with the late Victorian and Edwardian eras in the British Empire, the Gilded Age in the United States, the Belle Époque in the Third French Republic, and the Silver Age in the Russian Empire.
