Prague is the capital of Czech Republic and has over 1.3 million inhabitants, so I'd say it qualifies as a "major city"

I love Prague and I spent a quarter of century living there, but its status as a major city depends on context.

In the list of world cities by population, it ranks 403rd.

For Czechs or Central Europeans in general, it is a major city, but not in worldwide context.

On the other hand, Prague would be much higher if the official population number was accurate at all - since this official statistic in Czechia relies purely on the number of registered people and does no further analysis. There's over a million people more than the official number says - that's well known even to the government. Analysis of mobile device traffic and other stuff like that suggests multiple millions.

I'd definitely say it's a major EU city. Maybe even a major The West city. I agree that it's hard to compare it to places in Asia, though.

Hard to trust a map which places "Bali, Indonesia" where "Paris, France" should be.
