Question

why did the french national convention abolish slavery in 1794? *
to weaken the power of the catholic church
to gain support from the revolutionaries in saint - domingue
to increase profits from colonial trade
to align with british policies

Explanation:

The slave - owning system in Saint - Domingue (modern - day Haiti) was in turmoil due to slave revolts. The French National Convention abolished slavery in 1794 in part to gain the support of the revolutionaries in Saint - Domingue, who were fighting against the slave - owning regime there. It had little to do with weakening the Catholic Church, increasing colonial trade profits, or aligning with British policies.

Answer:

To gain support from the revolutionaries in Saint - Domingue
