What led to a rapid increase in the demand for food grains in 1789?

The various reasons that led to the increase in the demand for food grains in 1789 were:

• The Sudden increase in the population of France from 23 million to 28 million led to the increase in the demand for food grains.

• Also due to the drought or hail, the production of the food grains decreased and this led to the situation of subsistence crisis where citizens don’t have enough food grains to consume.
