Liberal and nationalist uprisings in the early 1800s challenged the conservative order in Europe. There were clashes between conservatives who wanted to maintain traditional monarchies, liberals who wanted limited democracy, and radicals who believed in liberty and equality for all. Nationalist movements developed seeking independence for nations with common cultures and histories. Throughout the 1830s and 1840s, nationalists and liberals launched revolts across Europe, but the conservative powers largely crushed these uprisings and maintained control until reforms began in the late 1840s.
