Answer:
The space suit
Though the first man stepped on the moon in 1969, in the 1930s astronomers and physicists were already planning for the voyage to outer space. Emilio Herrera Linares, a Spanish military colonel, is credited with being the first to design a pressurised suit which was used in a high-altitude balloon flight in 1936.
The modern mop
While the mop isn’t the most glamorous of inventions, it certainly is one of the most useful. People had been using rags to wash floors since the 15th century but it was in the 1960s that the engineer Manuel Jalón Corominas had the idea to create a purpose-built mop with a bucket to ring the water out in.

that's just a few ^_^!!!
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.
<span>In addition, the Tsar and his family were not killed during the Russian Revolution. They were kiled by the Bolsheviks during the Russian Civil War in July 1918, nine months after the October Revolution had ended.</span>
