Does "subject" still apply to inhabitants of monarchies nowadays? [closed]

When it comes to the following meaning of word subject (from here):

a person who lives in or who has the right to live in a particular country, especially a country with a king or queen

Although the definition is broad and seems like a synonym for citizen, I wonder if it is correct to use subject to refer to common citizens of countries like England or Japan nowadays.

Or does the word imply some degree of subjugation, being more suitable to refer to people of older colonial times (like British subjects living in colonial India)?

Thanks!

I remember that the passport I had as a child in the 1960s called me a British subject, but citizen is preferred nowadays.
