Final answer:
Vladimir Putin has weakened regional authority and centralized power in Russia through changes to the governorship and his economic policies.
Step-by-step explanation:
During Vladimir Putin's presidency, he has weakened regional authority and centralized power in Russia. One way he has done this is by changing the structure of the governorship in the oblasts and krais. Previously, the governor was an elected position, but Putin changed it to strengthen the power of the central state. Now, the governor is appointed by the central government, reducing the authority of the regions.
Another way Putin has centralized power is through his economic policies. He has focused on strengthening the Russian economy, which has attracted foreign investors and made Russia a major player in the global economy. However, this growth has not been evenly distributed, and many people in Russia still suffer from poverty and social problems.
Overall, Putin has taken steps to weaken regional authority and consolidate power in the central state, giving him more control over the country.
