A diverse variety of informal political groups emerged during the presidency of Vladimir Putin. They include remnants of the Yeltsin family, Saint Petersburg lawyers and economists, and security-intelligence elements called the siloviki.
When Putin came to power, he had few protégés or long-term associates, and had to balance various competitive elements as he crafted his team. In contrast to the Yeltsin years, Putin's regime was marked by personnel stability, a gradual elevation of trusted associates and coalition-building across competing interests both within the presidential administration and with other political actors.
As President Vladimir Putin, former employee of the Leningrad and Leningrad Oblast KGB Directorate and former Chief of the Committee for External Relations of Saint Petersburg Mayor's Office, had come to the presidency in 2000, many political observers noticed quick career promotion of bureaucracy and businesspeople from Saint Petersburg to the federal power bodies (especially the Presidential Executive Office, a very influential institution that has always been totally controlled by the presidential authority) and large state-controlled companies (such as Gazprom and Rosneft) and their struggle against old Moscow elites loyal to Boris Yeltsin's family, known as Family group, as well as against influential media tycoon Boris Berezovsky and his allies, who helped Putin on his way to power in 1999–2000.
According to Associate Professor of Political Science John P. Willerton, it is difficult to make general judgements about the various informal groups, their backgrounds and political preferences.
