based on abstract ideas, and preferred 'organic' reform. He is remembered as a father of modern Anglo-conservatism. In response to such critiques, the American revolutionary Thomas Paine published his book The Rights of Man in 1791 as a defence of the ideals of the French Revolution. The spirit of the age also produced early works of feminist philosophy – notably Mary Wollstonecraft's 1792 book: A Vindication of the Rights of Woman.

Meanwhile, the Spanish Empire began to unravel as French occupation of Spain weakened Spain's hold over its colonies, providing an opening for nationalist revolutions in Spanish America. As a direct result of the Napoleonic Wars, the British Empire became the foremost world power for the next century, thus beginning Pax Britannica. France had to fight on multiple battlefronts against the other European powers. A nationwide conscription was voted to reinforce the old royal army made of noble officers and professional soldiers. With this new kind of army, Napoleon was able to beat the European allies and dominate Europe.

When Napoleon eventually lost and the monarchy reinstated in France these ideals survived and led to the revolutionary waves of the 19th century that brought democracy to many European countries. With the success of the American Revolution, the Spanish Empire also began to crumble as their American colonies sought independence as well. In 1808, when Joseph Bonaparte was installed as the Spanish King by the Napoleonic French, the Spanish resistance resorted to governing Juntas. When the Supreme Central Junta
