The British spelling of dogmatization; the process of turning ideas or beliefs into rigid, unquestionable dogmas.
From dogmatise (British spelling) + -ation (suffix forming nouns of action/result). This is the variant spelling used in Commonwealth English countries like the UK and Australia.
The 'isation' vs 'ization' spelling difference is one of the clearest remaining divides between American and British English—and it goes back to Latin roots where both -atio and -atio naturally evolved differently!
