He was the eleventh child of John VI, Count of Nassau-Dillenburg and Countess Elisabeth of Leuchtenberg.
After the death of his father, the county of Nassau was divided among his five living sons, Ernst Casimir followed him as Count of Nassau-Dietz.
Ernst Casimir was primarily known as an outstanding military leader during the Eighty Years War. He served under Maurice of Nassau, Prince of Orange in the siege of the cities of Steenwijk and Oldenzaal, and Frederick Henry, Prince of Orange during the Siege of Groenlo (1627) and the Siege of 's-Hertogenbosch. As Stadholder of Groningen he founded the Nieuweschans fortress in 1628. Although he owned little in Friesland, he was popular there, and people granted his heir the right to rule after his death.
