Imperial heir Marcus Aurelius is betrothed in 139 to Antoninus’ daughter Annia Galeria Faustina.

Antoninus makes few initial changes on becoming emperor, leaving intact as far as possible the arrangements instituted by Hadrian.

In Britain, however, Antoninus decides to follow a new, more aggressive path, with the appointment of a new governor in 139, Quintus Lollius Urbicus.

Antoninus Pius recognizes the king of the Quadi, who becomes an ally of Rome, in 140.

The Quadi and Marcomanni, perhaps originating north of the River Main had migrated into what is now Moravia, western Slovakia and Lower Austria where they had displaced Celtic cultures and were first noticed by Romans in 8–6 BCE, briefly documented by Tacitus.

In his Germania, Tacitus only mentions the Quadi in the same breath as the Marcomanni, alike in warlike spirit, alike governed by "kings" of their own noble stock, "descended from the noble line of Maroboduus and Tudrus," the "Tudric" line apparently kings among the Quadi.

The royal powers of both tribes are also alike, according to Tacitus, in being supported by Roman silver.

Their neighbors are the Marcomanni to the west, proto-Slavic tribes to the north, Sarmatian Iazgyians and Asding Vandals arriving to the east somewhat later, and the Roman Empire to the south.

Mithridates IV of Parthia and his son Sanatruces II had taken up the diadem during the invasion of Mesopotamia by the Roman emperor Trajan (98–117) in 116, but were defeated.

After the death of Osroes I in 129, Mithridates IV had assumed the throne and continued the struggle with the rival king Vologases III of Parthia (105–147).

He dies in an attack on Commagene in 140.

Valentinus, an Egyptian by birth and a leading exponent of gnosticism in Alexandria, had moved to Rome in about 136, where he aspires to become pope.

In this year, according to Eusebius, Hyginus had succeeded Telesphorus as pope, instituted godparents at baptism to assist the newly born during their Christian life, and decreed that all churches be consecrated.

Pius, in turn, succeeds Hyginus as pope, possibly in 140.

The Qiang forces annihilate a Han force led by Ma Xian in 141 and set fire to the tomb-gardens of a number of Western Han emperors in the Chang'an region.

Agrarian rebellions eventually start again in Jing (modern Hunan, Hubei, and southern Henan) and Yang (modern Jiangxi, Zhejiang, and central and southern Jiangsu, Anhui) provinces and will not be pacified for the rest of Emperor Shun's reign.

Also in 141, Liang Shang dies.

Inexplicably, Emperor Shun gives his post to his son Liang Ji and gives Liang Ji's post to his younger brother Liang Buyi.

Liang Ji proceeds to seize power at every opportunity, and even though Liang Buyi tries to encourage his brother to be moderate in behavior, his pleas fall on deaf ears.

Claudius Ptolemy, apparently completing his astronomical observations in 141, produces the Geography, an effort to map the known world.

Drawing on the work of Hipparchus, Strabo, and Marinus of Tyre, Ptolemy lists latitudes and longitudes of important locations, with accompanying maps and a description of techniques of mapmaking.

Antoninus, a more traditional builder than Hadrian or Trajan, begins construction of the Temple of Faustina, a monument to his deified late spouse in about 141.

Now adapted to the church of San Lorenzo in Miranda, it stands in the Forum Romanum, on the Via Sacra, opposite the Regia.

Herodes Atticus, a fabulously wealthy financier and landowner from Athens, who rises to be consul of Rome in CE 143 (and whose bequests still adorn his home city), is one example of the new Romanized Greek citizens.

Antyllus, a Greek surgeon living in Rome, describes the types of aneurysms and creates a taxonomy related to the lesions' potential for rupture.

He develops specific instructions for a number of operations, also listing the indications and contraindications and describing the complications that could arise from the operations.

His operation for aneurysm will remain the standard procedure until the nineteenth century.
