The Austrian Empire was dismantled ......
The Ottoman Empire was dismantled .......
Let me add: British Empire was dismantled, Frankish (Germanic) Empire and later forms of it (EU form included) was dismantled, USA Empire in its NATO form was dismantled, Japan Empire was dismantled, Roman Empire was dismantled, Western Roman Empire was dismantled, Eastern Roman Empire was dismantled, etc.
Russia's turn.
Well, you may desire for it but, Russian Empire can`t be compare to above mentioned.
Why? Because Empires in Europe, above mentioned, were primarily formed to conquer Slavs and spread onto Slavic lands for colonial reason, as I said. Forming Rus idea was different.
First you equals Huge with Empire. That`s mistake. Then, Russia was founded as the desperate act of Slavic Rus and other tribes to merge having seen how Slavs suffer and retreat due to Drang Nach Osten since the Roman era. So they merged. Then they bordered with Germanized (so previously Slavic) regions which were hostile to Slavs. So they defeated oppressors and merged with those lands, too. Then they continued to spread on the wild wastelands of Siberia, etc where they encountered small tribes on a gigantic territories. Having state organization they merged those tribes, too.
Similarly how we comprehend China and India.
If we can imagine huge Slavic country from Eastern Germany to the Balkans and Kamchatka it shouldn't be considered Empire in pejorative sense. We can name it Russia, Poland or Serbia but we are still within borders of Slavic civilization.
See, that is one of reasons why was Slavic history always falsified by many above mentioned dismantled Empires. Keep people without information and then spread propaganda. Slavic Empire from Europe to Eurasia would be always natural thing to environment, and not something superimposed on others for colonial reasons. Slavic Empire is just merging of Slavs and dealing with hostiles. Evolution. Other Empires in Europe, above mentioned, were primarily formed to conquer Slavs, as I said.
Slavic Rus state no matter how huge wasn`t formed to conquer Frankish Empire. But Frankish Empire was formed to conquer Slavs.
