In the late 4th century, Ancyra became something of an imperial holiday resort. After Constantinople became the East Roman capital, emperors in the 4th and 5th centuries would retire from the humid summer weather on the Bosporus to the drier mountain atmosphere of Ancyra. Theodosius II (408–450) kept his court in Ancyra in the summers. Laws issued in Ancyra testify to the time they spent there.
