Kaiser

During the First World War, anti-German sentiment was at its zenith; the term kaiser—especially as applied to Wilhelm II, German Emperor—thus gained considerable negative connotations in English-speaking countries.

As a result of his long reign from 1848 to 1916 and the associated Golden Age before the First World War, this title often has still a very high historical respect in this geographical area.

It has been suggested, on the grounds of an anecdote reported in e.g. Suetonius (Divus Julius 79.2), that Caesar himself once used his cognomen by way of a title; but this is ultimately unlikely.

[4] Although the British monarchs styled "Emperor of India" were also called Kaisar-i-Hind in Hindi and Urdu, this word, although ultimately sharing the same Latin origin, is derived from the Persian Kaysar, not the German Kaiser.

According to Duden, this proverb goes back to the mostly bright sunshine on 18 August, the birthday of Emperor Franz Joseph I of Austria.

[11] After 1273, the Habsburgs provided most of Holy Roman Kings or Emperors, so they saw themselves as legitimate heirs to the title they adopted.

In 1867 the Austrian Empire was divided into the state of Austria-Hungary (the so-called Danube Monarchy), with Franz Joseph I, like his successor Karl I, being Emperor of Austria and King of Hungary.
