"History

The roots of Rational Process go back to the original spiral model of Barry Boehm. The Rational Approach was developed at Rational Software in the 1980s and 1990s.

In 1995 Rational Software acquired the Swedish Company Objectory AB. The Rational Unified Process was the result of the merger of the Rational Approach and the Objectory process developed by Objectory founder Ivar Jacobson. The first results of that merger was the Rational Objectory Process, designed to an Objectory-like process, but suitable to wean Objectory users to the Rational Rose tool. When that goal was accomplished, the name was changed. The first version of the Rational Unified Process, version 5.0, was released in 1998. The chief architect was Philippe Kruchten."
