Britain's £1.65 Billion War Against Napoleon: A Historical Analysis

The Napoleonic Wars, spanning from 1803 to 1815, incurred a cost of £1.65 billion for Britain, equivalent to approximately £190 billion today. This was financed through government loans and a new income tax introduced in 1799. Following the execution of King Louis XVI on 21 January 1793 and French advances in late 1792, tensions escalated. France declared war on Britain and the Netherlands on 1 February 1793. The Treaty of Amiens, which lasted from 1802 to 1803, collapsed when Britain declined to withdraw from Malta, leading to a renewed declaration of war on 18 May 1803. Napoleon's Continental System, initiated with the Berlin Decree on 21 November 1806, could not withstand British naval dominance. The Peninsular War commenced in November 1807. After abdicating in April 1814 and returning in March 1815, Napoleon faced defeat at Waterloo on 18 June 1815.
