Louis' cousin, the Duke of Orleans was the one responsible for spreading rumors about Louis' wife which caused people to get very angry.
Louis was officially arrested on 13 August and sent to the Temple, an ancient Paris fortress used as a prison.
On September 21, the National Assembly declared France to be a republic and abolished the monarchy.

Louis was made to go on trial as an ordinary citizen, and he was quickly proclaimed guilty.
 Louis Capet had no allies in the Convention, but the Girondins at least wanted to spare his life.
The Montagnards wouldn't hear of it; Louis must die.
Robespierre convinced the people that the monarch must die for the republic to live.
For the last time, he was reunited to his family and promised to come back the next morning but he did not.
On his way to the guillotine, Louis Capet ominously prophesied, "I trust that my death will be for the happiness of my people, but I grieve for France, and I fear that she may suffer the anger of the Lord" but his speech was drowned out by a roll of drums.
On January 21, 1793, the man they had once called “King” was no more.
Marie Antoinette, the Queen, was executed months later.
