George IV ruled between 1820-1830. George IV was the eldest son of George III.
At the age of 21 he fell in love with a Roman Catholic, Maria Anne Fitzherbert. He
married Maria in an unofficial and legally void marriage, because the King's assent
was never requested and no doubt it wouldn't have been granted. Law at the time
dictated that those who married Roman Catholics were ineligible to succeed to the
Throne. George IV was known to be a prolific gambler, womanizer and a heavy
drinker.
In an attempt to please and to receive money from the parliament (to pay off his
large debts) he agreed to marry his cousin, Caroline of Brunswick in 1795. After
the birth of their daughter Princess Charlotte in 1796 they separated. His daughter
Charlotte died in 1817 during pregnancy delivering a still-born son. George IV
therefore was succeeded by his brother William IV.
