Bahram V dies after an eighteen-year reign, and is succeeded by his son Yazdegerd II as the fifteenth Sassanid king of the Persian Empire.

Aelia Eudocia, wife of Theodosius II, goes on a pilgrimage in 438 to Jerusalem, bringing back with her holy relics to prove her faith.

She arranges to remove the ban on Jews' praying at the Temple site, and the heads of the Jewish Community in Galilee issue a call “to the great and mighty people of the Jews” which begins, “Know that the end of the exile of our people has come!”

In the Suebic Kingdom of Galicia, King Hermeric, after suffering from a seven-year illness, abdicates and hands over power to his son, Rechila. Rechila is married to a daughter of Wallia, the Visigothic king from 415 to 419.

Rechila has a sister, Ricina, and a brother, Ricimer, who will later become the de facto ruler of the Western Roman Empire.

Determined to expand the Suevic kingdom, Rechila seeks to fill the power vacuum left by the departing Vandals and Alans. In 438 CE, he achieves a major victory, defeating Andevotus, the comes Hispaniarum, at the Genil River (Singillio), further consolidating Suevic dominance in Hispania.

Theodosius II forbids the divulging of secrets of naval carpentry, among other things, probably to avoid its spread to the rising Vandal power in North Africa.

A gentle, scholarly, easily dominated man who allows his government to be run by a succession of relatives and ministers, Theodosius supervises compilation of the Theodosian Code, published in February 438, which codifies the laws issued after 312.

The code outlines social restrictions against the Jews, placing limitations on where they can live and what they can wear.

Subject to extraordinary taxation, Jews may neither hold public office, build synagogues, or hold slaves, which last measure effectively bars them from agriculture.

Greek becomes an official language in the Eastern Roman Empire in 439.

Theodoret, bishop of Cyrrhus (Syria) from 423, has converted more than one thousand Marcionites in his diocese.

Yazdegerd II moves his court to Khorasan in the beginning of his reign to face the threat from the White Huns.

This results in Yazdegerd gaining control of Bactria, which secures the eastern flank of the Sassanid Empire.

The Great Lavra of St. Sabbas the Sanctified, known in Arabic as Mar Saba, is a Greek Orthodox monastery overlooking the Kidron Valley n the West Bank east of Bethlehem.

The year 483 is the traditional date for the founding of the monastery by Saint Sabas of Mutalaska, Cappadocia.

Today housing around twenty monks, it is considered to be one of the oldest inhabited monasteries in the world, and still maintains many of its ancient traditions.

One in particular is the restriction on women entering the main compound.

The Women's Tower, near the main entrance, is the only building that women can enter.

Hun and Roman envoys meet at Margum (modern Bosnia and Herzegovina), an important market town on the Sava River.
