How and why do you think the terror came to an end

answer:

how:

ironically, the  end  of the  terror  was brought about by those who  were  sick of the bloodshed and by those who sought for more. by the  end  of the  terror, 16,594 official death sentences  were  declared and carried out in france, of which 2,639  were  in paris.

why:

on 17 july 1794, sixteen nuns attracted much attention by singing a religious song as they  were  being executed for treason. the  terror  ended ten days later, when several important leaders of the  reign of terror were  executed, including saint-just and robespierre
