A constitutional referendum was held in the Batavian Republic in 1798.
After a previous referendum in 1797 resulted in a coup d'état, a new constitution was written.
On 23 April 1798, a referendum was held about the new constitution.
After the referendum, a new coup d'état was done by the Unitarians, and the constitution became effective in July 1798.
The French, who had a big influence in the Batavian Republic, were not satisfied with the 1798 constitution, so a new constitution was written, for which a referendum in 1801 was organized.
