autorytarny Anglais:

One of the band members was very authoritarian and the rest couldn't stand him any longer.

an authoritarian regime/government/ruler

The lives of the citizens were strictly controlled by an authoritarian regime.

In my analysis I rely considerably on the types of authoritarian behaviour first analyzed by Kurz.
