Ferdinand I of Austria vs William IV

Ferdinand I became Emperor of Austria upon the death of his father Francis II. His reign was marked by his epilepsy and mental incapacity, leading to governance by a regency council dominated by Metternich.

A series of uprisings across the Austrian Empire demanded liberal reforms and national autonomy. Ferdinand I was forced to dismiss Metternich and promise a constitution, but the revolts were eventually suppressed.

Under pressure from the court and military, Ferdinand I abdicated the throne in favor of his nephew Franz Joseph. This ended his ineffective reign and allowed a new, more capable ruler to take control.

William IV served in the Royal Navy from age 13, rising to the rank of admiral. He saw action in the American Revolutionary War and later served as Lord High Admiral. His naval experience earned him the nickname 'Sailor King'.

William IV gave royal assent to the Reform Act, which reformed the British electoral system. It abolished rotten boroughs, redistributed seats to industrial cities, and expanded the electorate. This act was a major step toward democratic representation.

William IV gave royal assent to the Slavery Abolition Act, which abolished slavery throughout the British Empire. The act provided for the emancipation of slaves and compensation to slave owners. This was a landmark in human rights.

William IV died of heart failure at Windsor Castle at age 71. He was buried in St George's Chapel. His death ended the personal union with Hanover, as Salic law prevented Queen Victoria from inheriting Hanover. His reign saw significant reform.
