Russia is one of the clearest examples in the world of the gap between formal institutions and actual rule. On paper it has elections, a constitution, federalism, courts, parties, and a legislature. In practice those institutions no longer operate as independent centers of authority. They are arranged around the presidency and expected to ratify, administer, or justify decisions made closer to the Kremlin core.
That was not inevitable from the start. The Russian Federation began the 1990s with real political conflict, noisy media, competitive elections, and powerful regional actors. But the constitution born out of the 1993 crisis already concentrated huge power in the presidency. Vladimir Putin did not have to invent an overpowered executive from scratch. He inherited one, then used state resources, coercion, patronage, and fear to make the rest of the system answer to it.
