Государственный секретарь Святого Престола
The curial office of Cardinal Secretary of State in many ways evolved from the roles formerly filled by cardinal-nephews. From 1644 to 1692, the power of the Cardinal Secretary of State was essentially inversely proportional to that of the Cardinal Nephew, to whom the Secretariat was subordinate. During some pontificates, for example that of Pope Pius V (1566–1572) and his nephew Michele Bonelli, the cardinal-nephew and secretary of state were one and the same.
