William IV: The Life and Reign of the Sailor King

William IV served as the King of the United Kingdom of Great Britain and Ireland and the King of Hanover from June 26, 1830, until his death in 1837. As the third son of King George III and Queen Charlotte, William was not originally expected to inherit the throne. However, he eventually became the last king and penultimate monarch of the House of Hanover, a royal dynasty that ruled both Britain and Hanover.

Known affectionately as the "Sailor King" due to his early career in the Royal Navy, William's life was marked by a blend of naval discipline, complex personal relationships, and a reign that bridged the gap between traditional monarchy and modern constitutional reform.

Early Life and Naval Ambitions

Born on August 21, 1765, at Buckingham House, William was baptized at St James's Palace. Unlike his elder brothers, his path was steered toward the sea. He became a lieutenant in 1785 and captain of the HMS Pegasus in 1786, serving in Newfoundland and Nova Scotia.

During his time in the West Indies, William served under the legendary Horatio Nelson. Nelson held William in high regard, noting that he was superior to two-thirds of the naval list in his professional capabilities and exemplary in his respect for superiors. The two developed a close friendship, with William even giving the bride away at Nelson's wedding.

The Transition to Nominal Rank

William ceased active service in 1790, having commanded the HMS Andromeda and the HMS Valiant. Despite his eagerness to serve during the French Revolutionary and Napoleonic Wars, he was never given another active command. This was attributed to several factors, including a broken arm sustained during a fall while intoxicated and a speech he delivered in the House of Lords opposing the war.

Although he was named an admiral in 1798 and Admiral of the Fleet in 1811, these titles were purely nominal. His closest encounter with combat occurred in 1813 during a visit to British troops in the Low Countries, where a bullet pierced his coat while he watched the bombardment of Antwerp.

Personal Life and Relationships

William's personal life was unconventional for a royal. From 1791 to 1811, he cohabited with the Irish actress Dorothea Jordan. The couple shared a domestic and happy life, primarily residing at Bushy House. Together, they had ten illegitimate children, who were given the surname "FitzClarence."

The relationship ended in 1811, largely due to financial pressures. Following the split, Mrs. Jordan was provided a financial settlement but eventually died in poverty in France in 1816. In the years following, William attempted to marry wealthy heiresses to clear his debts, but these efforts failed.

Marriage to Princess Adelaide

The death of his niece, Princess Charlotte of Wales, in 1817 created an urgent need for a legitimate heir within the family. As the healthiest of George III's surviving sons, William became the primary candidate to secure the succession. On July 11, 1818, he married Princess Adelaide of Saxe-Meiningen, who graciously accepted William's existing children.

The Lord High Admiral and Accession

In 1827, William was appointed Lord High Admiral, the first person to hold the office individually since 1709. However, his tenure was fraught with conflict with his Council of Admiralty officers. After he took a squadron to sea for ten days without notifying his superiors, King George IV requested his resignation, which William granted.

Upon the death of George IV on June 26, 1830, William ascended the throne at age 64. At the time, he was the oldest person to ever assume the British throne, a record that stood until 2022.

Reign and Political Legacy

William IV's reign was characterized by a desire for frugality and a struggle to balance opposing political factions. His coronation on September 8, 1831, reflected this; he drastically reduced the budget from the £240,000 spent by his brother to less than £30,000, leading critics to mock it as a "Half Crown-nation."

Social and Legislative Reform

The era of William IV was one of significant societal change. His government enacted several landmark pieces of legislation:

Factory Act 1833: Aimed at preventing child labour.
Slavery Abolition Act 1833: Emancipated slaves throughout the British colonies.
Poor Law Amendment Act 1834: Standardized the provision of aid for the destitute.

While reformers felt he did not go far enough and reactionaries felt he conceded too much, modern historians view William IV as a capable constitutional monarch who successfully navigated the tensions between two bitterly opposed political factions.

Death and Final Years

William IV died at 2:12 am on June 20, 1837, at Windsor Castle, aged 71. He was buried on July 8 in the Royal Vault at St George's Chapel. He was attended in his final days by Queen Adelaide, who remained by his side devotedly.
