After 1848, the autocratic monarchies of Central and Eastern Europe introduced various changes, including abolishing serfdom and bonded labour in the Habsburg dominions and Russia. The Habsburg rulers also accorded more autonomy to the Hungarians in 1867. Political rights were extended to men in most of these states, but women still had to face discrimination. It was only in the twentieth century that voting rights were extended to women in most parts of Europe. Until then, various Women Suffrage movements and demonstrations were held for equal political rights for women.
