The main event that ended the Russian monarchy was the February Revolution. It was a spontaneous demonstration against the Tsar's government which turned riotous and spread to many other cities. The Tsar tried to order police and military forces to put down the riots, but they refused to obey him. In fact, many soldiers even joined in the riots.
Tsar Nicholas realized that the only way to end the violence was to abdicate his throne. He signed the abdication papers in March 1917 ending 300 years of the Romanov monarchy. The Provisional Government was instituted to govern the country until a Constituent Assembly could be seated, but the Provisional Government was overthrown in the October Revolution also known as the Bolshevik Revolution. The Bolshevik Revolution is not the revolution which ended the Russian monarchy, because the monarchy had already ended 8 months earlier.

The major similarity between the two documents is that both of them are limits on the power of the government. A secondary similarity is that they are both written contracts of sorts that spell out what governments can and cannot do. The idea that a government can be limited was a novel one in the 1200s.
