Answer:
Liberals wanted the rights to vote so they overthrew Charles X and established a constitutional monarchy.
Explanation:
"Liberals throughout Europe were encouraged to hope for a general social revolution, but most were disappointed... Their revolt was ruthlessly suppressed, and Poland was incorporated into the Russian Empire. Revolts in Italy and the German kingdoms were equally unsuccessful. Belgium declared its independence from the Netherlands, and it was recognized in 1831 as a separate nation." (Britannica)
