William Cavendish-Bentinck, also known as the 3rd Duke of Portland, served as Prime Minister of Great Britain twice, first in 1783 and then again from 1807 to 1809. His political career spanned several decades during a tumultuous period in British history, marked by the American War of Independence, the French Revolution, and the Napoleonic Wars. Despite holding the highest office in British politics twice, Portland is often considered more of a figurehead than a dominant leader, particularly during his second tenure, when his government was largely controlled by powerful political figures like George Canning and Lord Castlereagh.

Early Life and Political Background
Born: April 14, 1738, into the Cavendish-Bentinck family, William inherited the title of Duke of Portland in 1762 after the death of his father. The family was part of the British aristocracy, and as the Duke of Portland, he possessed immense wealth and landholdings, particularly in Nottinghamshire and Derbyshire.

Education: He was educated at Westminster School and later at Christ Church, Oxford, which was typical of the British aristocracy.

Political Career Begins
Portland entered politics as a member of the Whig Party, which was traditionally associated with promoting constitutional monarchism, the supremacy of Parliament, and opposition to absolute monarchy. He became Lord Chamberlain in 1765 under the ministry of Charles Watson-Wentworth, the Marquess of Rockingham, and established himself as a moderate and pragmatic politician.

First Term as Prime Minister (1783)
Portland’s first brief term as Prime Minister came in 1783 during a period of political instability following Britain’s defeat in the American War of Independence. At the time, the Fox-North Coalition, a partnership between Charles James Fox and former Prime Minister Lord North, dominated British politics.

Nominal Head of the Coalition: Portland became the figurehead of the Fox-North Coalition due to his Whig credentials, but he had little actual power or influence over policy. The real power lay with Fox, who managed foreign affairs, and North, who handled domestic policy.

Fall of the Coalition: Portland’s first term as Prime Minister ended after just a few months when the coalition government collapsed due to the failure of Fox’s East India Bill, which sought to reform the British East India Company’s governance in India. King George III opposed the bill and used his influence to ensure its defeat in the House of Lords. In December 1783, the coalition was dismissed, and Portland was replaced by William Pitt the Younger, a rising political star who would dominate British politics for the next two decades.

Political Life After 1783
After losing the premiership in 1783, Portland remained an important figure in the Whig Party and became a leading critic of William Pitt the Younger’s government, particularly on issues related to the French Revolution and the Napoleonic Wars. However, by the late 1790s, Portland’s political views began to shift, especially on matters of national security and the threat posed by revolutionary France.

Support for Pitt and the Tories: Portland eventually broke with Charles James Fox and his faction of the Whigs, particularly over Fox’s pro-French Revolutionary stance. Portland became more aligned with the Tory Party, especially on issues of defending Britain against the spread of revolutionary ideals.

Second Term as Prime Minister (1807–1809)
Portland’s second term as Prime Minister occurred in 1807 during a critical period of the Napoleonic Wars. By this time, Portland was an aging and ailing figure, and his health was rapidly deteriorating. His appointment as Prime Minister came after the collapse of the Ministry of All the Talents, a coalition government led by Lord Grenville that had attempted to implement a series of reforms, including the abolition of the slave trade.

Appointment as Prime Minister: Portland was chosen to head a government that was largely controlled by George Canning, the Foreign Secretary, and Viscount Castlereagh, the Secretary of State for War. His role was largely ceremonial, and his government was dominated by these two powerful and ambitious ministers, who often clashed over military and foreign policy.

Key Issues During His Second Term:
The Napoleonic Wars: The ongoing wars with Napoleon Bonaparte’s France were the central focus of British policy during Portland’s second term. His government oversaw British involvement in several key battles and campaigns, including the Peninsular War in Spain and Portugal, where the British supported resistance against French occupation.

Catholic Emancipation: One of the most contentious issues during Portland’s second term was the debate over Catholic emancipation, which sought to grant greater civil rights to Roman Catholics in Britain and Ireland. Portland’s government, like many Tory administrations of the time, opposed these reforms, contributing to divisions within the government.

Political Infighting: Portland’s second ministry was marked by intense political infighting, particularly between George Canning and Lord Castlereagh. The two men disagreed over the conduct of the war, particularly over the strategy for military campaigns in Europe. This culminated in a dramatic duel between Canning and Castlereagh in 1809, which embarrassed the government and undermined its authority.

Resignation and Death
By 1809, Portland’s health had deteriorated significantly, and he was no longer able to effectively manage the government. He resigned from office in September 1809, and just a few weeks later, on October 30, 1809, he died at the age of 71. His resignation marked the end of a largely ineffective second term, overshadowed by internal disputes and his inability to provide strong leadership.

Legacy
Despite serving two terms as Prime Minister, William Cavendish-Bentinck, the Duke of Portland, is often regarded as a weak and ineffective leader who served more as a figurehead than a driving force in British politics. His second term, in particular, is remembered more for the political conflicts between his ministers than for any significant accomplishments of his own.

However, Portland’s career highlights the complex and shifting nature of 18th-century British politics, where aristocratic influence, factionalism, and the growing power of professional politicians shaped the governance of the country. His willingness to break with his earlier Whig allies and align with the Tories also reflects the way in which foreign policy and national security concerns, particularly regarding revolutionary France, shaped political loyalties during this period.

Portland Place in central London and the Duke of Portland Stakes, a prestigious horse race, are named in his honor, though his political legacy remains one of limited accomplishment.
