Final answer:
The radicals and sans-coulottes' rise to power significantly influenced the French Revolution, leading to the end of the monarchy and the declaration of war on Austria. Radical redefinitions of government and social norms occurred, ultimately leading to Napoleon's rise and a turn towards conservative policies.
Step-by-step explanation:
The effects of the radicals and sans-coulottes gaining power during the French Revolution were significant in shaping the political landscape of France. As the radicals, including the Girondins and the more extreme Jacobins, gained influence, they propelled transformative policies and actions. Their support from the sans-coulottes, the lower working classes who were excluded from the aristocratic privileges, was pivotal in challenging the monarchy and pushing for revolutionary change.
During this period, the revolution took a more radical turn. The Jacobins, supported by sans-coulottes interests, championed the abolishment of the monarchy, leading to a rapid escalation of political turmoil. The violent overthrow and eventual execution of King Louis XVI marked a turning point, as France declared war on Austria, urged by the Girondins.
As these radical groups rose to power, their efforts were met with a mixture of success and resistance, influencing both internal and external conflicts. This rise ultimately contributed to the advent of an era marked by a radical redefinition of governmental structures and social norms. The initial revolutionary idealism gave way to a more conservative stance following the failure of the Terror and culminated in the rise of a popular authoritarian leader, Napoleon Bonaparte.
