Final answer:
Political parties in Russia have been unstable due to historical factors and socio-political problems. The lack of industrialization and desire for change, along with events such as the 1905 Revolution and aftermath of World War I, led to infighting and limited decision-making power for political parties in Russia.
Step-by-step explanation:
In Russia, political parties have been unstable due to a combination of historical factors and socio-political problems. At the beginning of the 20th century, Russia was still an agricultural country and had not undergone large-scale industrialization like Great Britain and Western Europe. This led to a desire for change and a new political system.
Furthermore, the 1905 Revolution and the aftermath of World War I also played a role in destabilizing political parties. The Bolsheviks, who followed socialist and Marxist ideologies, emerged as a political faction and pushed for violent revolution. After the revolution, newly-constituted political parties in the Duma struggled to counterbalance the Tsarist power, leading to infighting and little actual decision-making power.
Therefore, political parties in Russia were undermined by the lack of industrialization, historical events, and the concentration of power in the hands of the ruling elite.
