In 1641, Christian Louis inherited the Principality of Calenberg from his father, Duke George of Brunswick-Lüneburg, who had suddenly died. Like his father he resided at the Leineschloss in Hanover.

When in 1648 he also inherited the Principality of Lüneburg from his uncle, Frederick IV, Duke of Brunswick-Lüneburg, both subdivisions were ruled in personal union. However, Christian Louis gave Calenberg to his younger brother George William, and instead ruled the larger territory of Lüneburg at Celle Castle.

In 1642 Christian Louis became a member of the Fruitbearing Society. He married Sophia Dorothea, daughter of Duke Philipp of Schleswig-Holstein-Sonderburg-Glücksburg on October 9, 1653.

He died childless in 1665 and was succeeded by his brother George William, who on this occasion gave the Calenberg territory to his younger brother John Frederick. Both territories finally merged after George William's death in 1705 to the Electorate of Hanover under John Frederick's nephew George I Louis, Prince of Calenberg. Christian Louis's widow remarried and became Electress of Brandenburg as the second wife of the Great Elector.
