Cardinal Richelieu - Thirty Years' War

Thirty Years' War

Before Richelieu's ascent to power, most of Europe had become involved in the Thirty Years' War (1618–1648). France was not openly at war with the Habsburgs, who ruled Spain and the Holy Roman Empire, so subsidies and aid were given secretly to their adversaries. He subsidized the Dutch to fight against the Spanish via the Treaty of Compiègne in 1624. That same year, a military expedition, secretly financed by France and commanded by Marquis de Coeuvres, liberated the Valtelline of Spanish occupation. In 1625 Richelieu also sent money to Ernst von Mansfeld, a famous mercenary general operating in Germany in English service. However, in 1626, he made peace with Spain via the Treaty of Monçon. This peace quickly broke after tensions due to the War of Mantuan Succession.

In 1629, the Emperor Ferdinand II subjugated many of his Protestant opponents in Germany. Richelieu, alarmed by Ferdinand's influence, incited Sweden to intervene, providing money. In the meantime, France and Spain remained hostile over Spain's ambitions in northern Italy. At that time northern Italy was a major strategic item in Europe's balance of powers, serving as a link between the Habsburgs in the Empire and in Spain. Had the imperial armies dominated this region, France's very existence would have been endangered, as it would have been encircled by Habsburg territories. Spain was seeking papal approval for a universal monarchy. When, in 1630, French ambassadors in Regensburg agreed to make peace with Spain, Richelieu refused to uphold them. The agreement would have prohibited French interference in Germany. Thus, Richelieu advised Louis XIII to refuse to ratify the treaty. In 1631, he allied France to Sweden, who had just invaded the empire, in the Treaty of Bärwalde.

Military expenses put a considerable strain on the King's revenues. In response, Richelieu raised the gabelle (salt tax) and the taille (land tax). The taille was enforced to provide funds to raise armies and wage war. The clergy, nobility, and high bourgeoisie were either exempt or could easily avoid payment, so the burden fell on the poorest segment of the nation. To collect taxes more efficiently, and to keep corruption to a minimum, Richelieu bypassed local tax officials, replacing them with intendants (officials in the direct service of the Crown). Richelieu's financial scheme, however, caused unrest among the peasants; there were several uprisings in 1636 to 1639. Richelieu crushed the revolts violently, and dealt with the rebels harshly.

Because he openly aligned France with Protestant powers, Richelieu was denounced by many as a traitor to the Roman Catholic Church. Military hostilities, at first, were disastrous for the French, with many victories going to Spain and the Empire. Neither side, however, could obtain a decisive advantage, and the conflict lingered on until after Richelieu's death. Richelieu was instrumental in redirecting the 30 Years' War from the conflict of Protestantism versus Catholicism to that of nationalism versus Habsburg hegemony. In this conflict France effectively drained the already overstretched resources of the Habsburg empire and drove it inexorably towards bankruptcy. The defeat of Habsburg forces at the Battle of Lens, and their failure to prevent French invasion of Catalonia effectively spelled the end for Habsburg domination of the continent, and Olivares' personal career. Indeed, in the subsequent years it would be France, under the leadership of Louis XIV, who would attempt to fill the vacuum left by the Habsburgs in the Spanish Netherlands, and supplant Spain as the dominant European power.
