Lucius Verus
In 161, when she was between 11 and 13 years old, Lucilla's father arranged a marriage for her with his co-ruler Lucius Verus. Verus, 18 years her senior, became her husband three years later in Ephesus in 164. At this marriage, she received her title of "Augusta" and became a Roman Empress. At the same time, Marcus Aurelius and Lucius Verus were fighting a Parthian war in Syria.
