Dear Student,
The major changes that occurred in the political and constitutional scenario due to the French Revolution were
1. Feudalism was abolished. All individuals were declared equal.
2. At first, France became a constitutional monarchy. Later, the monarchy was abolished and France became a republic.
3. The Church was stripped of all powers to tax people. It's role was confined to the religious and spiritual guidance of people. There was now strict separatation of the church and the state.
Regards.
