text_A: Early Marxist movements were at odds with the traditional monarchies that ruled over much of the European continent at the time. Many European monarchies outlawed the public expression of communist views and the "Communist Manifesto", which began "[a] spectre [that] is haunting Europe", and stated that monarchs feared for their thrones. Advocacy of communism was illegal in the Russian Empire, the German Empire, and Austria-Hungary, the three most powerful monarchies in continental Europe prior to World War I. Many monarchists (except constitutional monarchists) viewed differences in wealth and political power as resulting from a divine natural order. The struggle between monarchists and communists was often described as a struggle between the Right and the Left.
text_B: Would a non-constitutional monarch likely oppose a progressive income tax?
YES.
