Answer:
The Third Estate (Peasants)
Step-by-step explanation:
the lowest social class in the Old Regime, made up 97% of the population, had three major groups - bourgeoisie, the workers of France's cities (tradespeople, apprentices, laborers, domestic servants), and peasants (80% of France's 26 million people)
this is important because thee people lacked privileges and were forced to pay very high taxes, which caused them to revolt (French Revolution)
