Ada, Countess of Holland

Ada (c. 1188 – 1234/37) was Countess regnant of Holland between 1203 and 1207, ruling jointly with her husband, Louis II of Loon.

[1] Ada was the only surviving daughter of Count Dirk VII of Holland and his wife Adelaide of Cleves.

Ada married Count Louis II of Loon to strengthen her position.

Their reign was short-lived, since Emperor Otto IV regarded William to have more right to the title Count of Holland in 1208.

Louis died in 1218, leaving Ada to live out the rest of her life in obscurity.
