clergy

nobility

3rd estate were the
big businessmen,merchants,court officials,lawyers etc.
peasants and artisans
small peasants,landless labour,servants.

in the 3rd estate some were poor and some were rich . and only the people of 3rd estate had to pay taxes while the 1st and 2nd estates enjoyed certain privileges by birth .

the most important of these was exemption of paying taxes to the state. the nobles further enjoyed feudal privileges . these included feudal dues,which they extracted from the peasants . peasants were obliged to render services to the lord - to work in his house and fields - to serve in the army or to participate in building roads.
3 estates

2nd estate= men of noble birth.also no taxes.
3rd estate= poor people peasents etc , they paid all taxes.
