How long have personal prelatures existed in the Church?

Although similar personal hierarchical structures already existed (such as military vicariates), the juridical figure of the personal prelature is the result of an apostolic desire of the Second Vatican Council that later took form in the present Code of Canon Law. The first to be erected was the prelature of Opus Dei, in the Apostolic Constitution Ut sit of John Paul II, on November 28, 1982.
