men strong, led by Urbain de Maillé-Brézé, who had fought in many battles and participated in the Siege of La Rochelle (1627–1628), and Jacques-Nompar de Caumont, duc de La Force. They broke the siege and drove off the Imperial forces. In 1648, at the end of the war, Frederick V's son Charles I Louis, Elector Palatine, was able to recover his titles and lands. To strengthen his dynasty, Charles I Louis arranged the marriage of his daughter Liselotte to Philip I, Duke of Orléans, brother of Louis XIV, King of France. In 1685, after the death of Charles Louis' son, Elector Charles II, King Louis XIV laid claim to his sister-in-law's inheritance. The Germans rejected the claim, in part because of religious differences between local Protestants and the French Catholics, as the Protestant Reformation had divided the peoples of Europe. The War of the Grand Alliance ensued. In 1689, French troops took the town and castle, bringing nearly total destruction to the area in 1693. As a result of the destruction due to repeated French invasions related to the War of the Palatinate Succession coupled with severe winters, thousands of German Calvinist Palatines emigrated in the early 18th century. They fled to other European cities and especially to London (where the refugees were called "the poor Palatines"). In sympathy for the Protestants, in 1709–1710, Queen Anne's government arranged transport for nearly 6,000 Palatines to New York. Others were transported to Pennsylvania, and to South Carolina. They worked their passage and later settled in the English colonies there. In 1720, after assigning a major church for exclusively Catholic use, religious conflicts with the mostly Protestant inhabitants of Heidelberg caused the Roman Catholic Prince-Elector Charles III Philip to transfer his court to nearby Mannheim. The court remained there until the Elector Charles Theodore became Elector of Bavaria in 1777 and established his court in Munich. In 1742, Elector Charles Theodore began rebuilding the Palace. In 1764, a lightning bolt destroyed other palace buildings during reconstruction, causing the work to be discontinued. 1803 to 1933 Heidelberg fell to the Grand Duchy of Baden in 1803. Charles Frederick, Grand Duke of Baden, re-founded the university, named "Ruperto-Carola" after its two founders. Notable scholars soon earned it a reputation as a "royal residence of the intellect". In the 18th century, the town was rebuilt in the Baroque style on the old medieval layout. In 1810
