The country that was called the Helvetic Republic after France tried to impose central authority over the Helvetian people is Switzerland.
After the French Revolution, France wanted to spread its revolutionary ideals and extend its influence beyond its borders.
As part of this effort, France invaded Switzerland in 1798 and established the Helvetic Republic in place of the previous Swiss Confederation. The Helvetic Republic was a centralized state that aimed to modernize Switzerland and introduce French revolutionary reforms.
