Of or relating to opposition against dynastic power and hereditary rule; antidynastic in character.
From antidynastic + -al (adjective suffix), creating a variant form with similar meaning but slightly more formal tone.
This older form appears in 18th and 19th-century political writings—it's the verbose way revolutionary thinkers said 'we reject hereditary power,' and it sounds more learned.
