I would have to guess that the correct description of revolution is where the people are not getting what the need or deserve so the people revolt toward the government, possibly overthrowing it, and create the government with its wants and needs. The outcome is the creation of the new government or monarchy with what the people want.
The correct answer is - he is the current president of Chechnya.
Ramzan Kadyrov is the the current president of Chechnya. Unlike the former presidents of Chechya that were in constant conflict with Russia, he is actually in very nice relations with the Russian authorities and they have a nice collaboration and mutual support in the recent years.
