What was “Tithes”?  


Christians and Muslims paid tithes, which was a religious tax.
Tithes have been paid for the support of the parish church and its priest since ancient times.
These payments were originally provided in kind (crops, wool, milk, young stock, etc.) and usually equaled a tenth (tithe) of the annual cultivation or stock rearing production.
In the second half of the 17th century, the practice was abandoned as the Church’s influence in political matters faded.

Final Answer:
Hence, the Tithes were a religious type of tax levied on one-tenth of the overall output by the church on the French peasants.
