The word for a person (usually a king or ruler) who holds absolute power, and exercises it in a cruel or oppressive way, is despota in Italian. It comes from the Greek despótēs which was the word for the “master of the house”. In ancient Italian, the word ended in an -o rather than an -a.
despota

Despota is a masculine and feminine noun, in that it can be used to indicate both male and female despots without any change in form. The only way to decipher the gender of the subject is to look at the definite and indefinite articles. In the plural form, the masculine ends with “i” while the feminine ends with “e”.
- il / la despota = the despot
- un / una despota = a despot
- i despoti = the despots (masc. plural)
- le despote = the despots (fem. plural)
- dei despoti = (some) despots (masc. plural)

After the 7th century, despota was the honorary title of the Byzantine emperor and subsequently the title of the sovereign’s sons, brothers and siblings, not to mention some vassal princes.

In a figurative sense, despota can refer to someone who abuses their authority at work or at home and expects to be blindly obeyed.
