After Ethiopia survived near destruction at the hands of Gragn, a different battle began. Instead of a military battle, it was a battle of ideas for Ethiopia's identity. Catholic missionaries began to arrive in Ethiopia in the late 1500s. And while some, like a man Petro Paez, legitimately hoped to find unity between Roman Catholics and Ethiopian Orthodox, others simply wanted Ethiopia become European. Walatta Petros was a brave and sometimes impetuous Ethiopian nun who resisted these attempts and helped preserve Ethiopia's heritage.
