Britain's prosperity was closely tied to its military fortunes, particularly in the 18th and 19th centuries. The country's naval power was crucial in maintaining its global empire and protecting its trade routes, which were essential for its economic growth. Britain's military victories also brought in wealth in the form of plunder and reparations. For example, the Seven Years' War (1756-1763) resulted in Britain acquiring Canada and Florida from France, as well as control over India. The Napoleonic Wars (1803-1815) also brought in significant wealth, including the seizure of the Danish fleet in 1807 and the capture of the French colonies of Martinique and Guadeloupe in 1809.
France
France's prosperity was also intertwined with its military fortunes, although to a lesser extent than Britain. The country's military victories in the 17th and 18th centuries helped to secure its borders and expand its territory. For example, the Peace of Westphalia in 1648 gave France control over Alsace and Lorraine, while the Treaty of Utrecht in 1713 gave France control over parts of Canada and the Caribbean. However, France's military defeats in the 19th century, such as the Franco-Prussian War of 1870-1871, led to economic decline and a loss of prestige.
Russia
Russia's prosperity was not as closely tied to its military fortunes as Britain's and France's. The country's vast natural resources and large population gave it a strong economy, even during times of military defeat. However, Russia's military victories did bring in some wealth, such as the conquest of Siberia in the 16th and 17th centuries, which gave Russia access to valuable fur resources.
