The main reason why Austria is included is the Habsburg dynasty. They are very important because they ruled an Empire which included Austria, Spain, Belgium, the Netherlands, Hungary, Bohemia, Spanish America, Portugal and many more. I can't think of any other dynasty that ruled over a bigger Empire, which they attained peacefully through marriage.
Spoiler :
Bohemia is a decent regional candidate too, better than Austria I'd say. Just my humble opinion of course.
