Landgraves Philip I, William V, and Maurice married descendants of King George of Bohemia; from William VI onwards, mothers of the heads of Hesse-Kassel were always descended from William the Silent, the leader of the Dutch to independence on the basis of Calvinism. The Landgraviate of Hesse-Kassel expanded in 1604 when Maurice, Landgrave of Hesse-Kassel inherited the Landgraviate of Hesse-Marburg from his childless uncle, Louis IV, Landgrave of Hesse-Marburg (1537–1604). During the Thirty Years' War, Calvinist Hesse-Kassel proved to be Sweden's most loyal German ally. Landgrave William V and, after his death

In 1567, the Landgraviate of Hesse, until then centered in Marburg, was divided among four sons, with Hesse-Kassel (or Hesse-Cassel) becoming one of its successor states. Kassel was its capital and became a centre of Calvinist Protestantism in Germany. Strong fortifications were built to protect the Protestant stronghold against Catholic enemies. Secret societies, such as Rosicrucianism flourished, with Christian Rosenkreutz's work Fama Fraternitis first published in 1617. In 1685, Kassel became a refuge for 1,700 Huguenots who found shelter in the newly established borough of Oberneustadt. Landgrave Charles, who was responsible for this humanitarian 
Title: Landgraviate of Hesse-Kassel
Content:  The Landgraviate of Hesse-Kassel (Landgrafschaft Hessen-Kassel), spelled Hesse-Cassel during its entire existence, was a state in the Holy Roman Empire that was directly subject to the Emperor. The state was created in 1567 when the Landgraviate of Hesse was divided upon the death of Philip I, Landgrave of Hesse. His eldest son William IV inherited the northern half of the Landgraviate and the capital of Kassel. The other sons received the Landgraviate of Hesse-Marburg, the Landgraviate of Hesse-Rheinfels and the Landgraviate of Hesse-Darmstadt. During the Napoleonic reorganisation of the Empire in 1803, the Landgrave of Hesse-Kassel was elevated to an Electorate and Landgrave William IX

Content:  In 1568 with the death of Landgrave Philip I, the Landgraviate of Hesse (Landgrafschaft Hessen), a German Principality of the Holy Roman Empire, was divided among his sons. With the extinction of the Hesse-Marburg and Hesse-Rheinfels lines by 1604, Hesse-Darmstadt, along with Hesse-Kassel, became one of the two Hessian states. While Hesse-Kassel converted to Calvinism and became one of the most zealous exponents of the Protestant cause in the Thirty Years' War, Landgrave George II remained a strict Lutheran and maintained a close alliance with Saxony, which led to a pro-Habsburg policy after 1642. Hesse-Darmstadt gained a great deal of territory from the secularization and modifications authorized by the Reichsdeputationshauptschluss of 1803. The acquisition of the Duchy of Westphalia, formerly owned by the Archbishop of Cologne, was significant, as were 
Title: Landgraviate of Hesse-Rotenburg
Content:  The line of Hesse-Kassel (or Hesse-Cassel) was founded by William IV, surnamed the Wise, eldest son of Philip the Magnanimous. On his father's death in 1567, he received one half of Hesse, with Cassel as his capital; this formed the Landgraviate of Hesse-Kassel. Additions were made to it by inheritance from his brother's possessions. His son, Maurice the Learned (1572–1632) was Landgrave of Hesse-Kassel from 1592 until 1627. Maurice turned Calvinist in 1605, became involved later in the Thirty Years' War, and, after being forced to cede some of his territories to the Darmstadt line, abdicated in 1627 in favour of 
Title: Electorate of Hesse
Content:  The Landgraviate of Hesse-Kassel originated in 1567 with the division of the Landgraviate of Hesse between the heirs of Philip I of Hesse ("the Magnanimous") after his death. Philip's eldest son, William IV, received Hesse-Kassel, which comprised about half the area of the Landgraviate of Hesse, including the capital, Kassel. William's brothers received Hesse-Marburg and Hesse-Rheinfels, but their lines died out within a generation and the territories then reverted to Hesse-Kassel and to the Landgraviate of Hesse-Darmstadt. The reign of the Landgrave William IX was an important epoch in the history of Hesse-Kassel. Ascending the throne in 1785, he took part in 
Title: Hesse
Content:  In the 12th century, Hessengau was passed to Thuringia. In the War of the Thuringian Succession (1247–1264), Hesse gained independence and became a Landgraviate within the Holy Roman Empire. It shortly rose to primary importance under Landgrave Philip the Magnanimous, who was one of the leaders of German Protestantism. After Philip's death in 1567, the territory was divided among his four sons from his first marriage (Philip was a bigamist) into four lines: Hesse-Kassel (or Hesse-Cassel), Hesse-Darmstadt, Hesse-Rheinfels, and the also previously existing Hesse-Marburg. As the latter two lines died out quite soon (1583 and 1605, respectively), Hesse-Kassel and Hesse-Darmstadt were the two core states within the Hessian lands. Several collateral lines split off during the centuries, such as in 1622, when Hesse-Homburg split off from Hesse-Darmstadt. In the late 16th century, Kassel adopted Calvinism, while Darmstadt remained Lutheran and subsequently the two lines often found themselves on
