The Hepthalites, also known as the White Huns, were first mentioned by the Chinese, who described them as living in Dzungaria around CE 125.

Chinese chronicles state that they were originally a tribe of the Yuezhi, living to the north of the Great Wall, and subject to the Rouran (Jwen-Jwen), as were some Turkic peoples at the time.

Their original name was Hoa or Hoa-tun; subsequently they named themselves Ye-tha-i-li-to (or, more briefly, Ye-tha), after their royal family, which descended from one of the five Yuezhi families which also included the Kushan.

They had displaced the Scythians and conquered Sogdiana and Khorasan before 425.

After that, they cross the Syr Darya (Jaxartes) River and invade Persian lands.

The buildings and pagan temples of the sanctuary at Olympia, disused since the banning of the Olympic Games by the emperor Theodosius I in 393, are demolished in 426 on the orders of Theodosius II.

The fate of the statue of Zeus, made in around 430-422 BCE by the famed Greek sculptor, painter, and architect Phidias, is a source of debate: the eleventh-century Eastern Roman historian Georgios Kedrenos recorded the tradition that it was carried off to Constantinople, where in 475 it was destroyed in the great fire of the Lauseion.

Others argue that it perished in 425 with the temple when it burned.

Bonifacius supports Valentinian, and resumes grain shipments from Africa.

However, Galla Placidia, under the influence of Aëtius, convicts Bonifacius of treason against the emperor.

Augustine completes “The City of God” in 426, dismissing the anti-Christian pagan position and instead interpreting history in terms of Christian revelation.

A centerpiece of the author’s argument is that of the "two cities:" the Christian city, devoted to God; and the earthly pagan city (Babylon) devoted to the devil; Babylon, open to moral confusion and strife, is scheduled ultimately for destruction.

Augustine begins developing a theology of church and sacrament to refute the doctrines of the Donatists.

Jangsu, the twentieth monarch of Goguryeo, the northernmost of the Three Kingdoms of Korea, has reigned from the age of nineteen reigned over the peak of Goguryeo's power, building on the territorial expansion of his father, King Gwanggaeto the Great.

Now entering his thirties, he has dedicated much of his efforts towards stabilizing a kingdom that had experienced great and sudden growth, a direct result of his father's conquests.

Jangsu has built a magnificent tomb for his father, and along with it an imposing four-meter tall tombstone carved from a single mass of granite and engraved with his father's accomplishments (now known as the Gwanggaeto Stele).

Of such imposing dimensions is the tomb and its grounds that it requires three hundred and thirty people to tend it at all times, called from different regions and tribal backgrounds to guard and clean the tomb in perpetuity: a demonstration of the effective consolidation of the Goguryeo kingdom and monarch's power at the time of Jangsu's succession.

In 427, he transfers the Goguryeo capital to from Guknaesong (modern Ji'an on the Sino-Korean border) to …

…P'yonggang (Pyongyang).

Many modern Chinese historians argue that since the early Goguryeo capital had been located in what is now China, the history of that kingdom prior to 427 should be regarded as Chinese history).

There are various reasons for this shift: to prepare for the offensive against Baekje and Silla in the south and to create a greater and more magnificent capital befitting a kingdom that has experienced large-scale expansion.

After moving the capital southward, King Jangsu decides to continue the conquests of his father.
