What events and why marked the end of the sovereignty of King Louis XVI of France?

Louis XVI was the last emperor before the French Revolution. It began with the fall of the Bastille prison, which in fact did not represent a serious force, and there were also few prisoners in it. However, it was more a symbol. Also, the rebels got hold of a large number of weapons. Which was then used to seize power.

A little later, the king was captured and executed. However, the loss of power began just with the capture of the prison. Except for the inept economic policy that brought the country to crisis.
