1 CE: start of the Common Era
Year 1 CE: for people then, just another year from Rome's founding and the year of Emperor Ping; Augustus holds the Mediterranean, Han holds the Middle Kingdom; between them, silk and Parthia.
Year 1 of the Common Era. Nobody then counts a "Common Era." A monk, Dionysius Exiguus, will invent the number five hundred years later, and it will spread later still. For people of that day it is just another year from the founding of Rome, the 754th, if you trust Roman counters. In China: a year of Emperor Ping's reign. The East has its own calendar; Judea has its own.
Christmas, which later gets tied to this point, most likely happened a few years earlier. In the "first year" itself the infant Jesus is no longer in the manger. There is Rome, which seems eternal. There is China, which seems central. Between them: Parthia, the steppe, and roads that carry caravans, not calendar ideas.
Rome and the Mediterranean
Rome is ruled by Octavian Augustus. The Republic still lives on paper: the Senate sits, consuls are elected. In practice one man holds the army, the provinces, and the right to say "no." The civil wars are over. They call it the peace of Augustus: Pax Romana. For a resident of Italy the peace really is quieter than under Caesar and Antony. For a resident of conquered Gaul or Judea, peace looks like taxes, a garrison, and someone else's law.
The empire rings the sea: Spain, Gaul, Italy, Greece, Asia Minor, Syria, Egypt, Africa. The Rhine and the Danube are almost the edge. Britain has not been taken seriously yet (that is Claudius, forty years on). Beyond the Rhine: Germans. Recently, in 9 BCE and around then, Romans pushed into Germany. Eight years after the "first year," in the Teutoburg Forest, three legions will fall. In year 1 that has not happened yet. It seems the eagles go wherever they want.
In Rome they write. Livy pulls his enormous history of the City. Ovid writes light and dangerous verse. Soon Augustus will exile him to the Black Sea. Virgil is already dead, but the Aeneid has become the empire's schoolbook: Rome as if appointed by the gods.
Judea is a client kingdom under Rome. Herod the Great died around 4 BCE. His sons divide the land. In Jerusalem, the Temple, high priests, different schools: Pharisees, Sadducees, radicals in the desert. There is tension. No big explosion yet. Jesus, if you follow the usual historians' chronology, is a child or adolescent somewhere in Galilee. Official Rome has not heard of him.
Egypt is Augustus's personal granary: grain for Rome. Alexandria is still a smart city: the library is no longer what it was under the Ptolemies, but Greek language and science are alive.
Parthia and east of the Euphrates
Rome's main equal enemy is Parthia. Cavalry, heavy horsemen, capital sometimes Ctesiphon, sometimes other courts. The border runs along the Euphrates. Sometimes they make peace, sometimes they fight. Nobody wins for good. Between them a buffer: Armenia, small kingdoms, quarrels over princes.
For a merchant, war matters less: silk from the east already reaches Rome. Not Chinese caravans in person, but a chain: China, Central Asia, Parthia, Syria. Romans pay in gold and glass. Chinese get horses and curiosities. Each side thinks the center of the world is theirs.
China
The dynasty is Western Han. Emperor Ping is a teenager. Behind him Wang Mang gathers strength, a relative on the female line, a man of order and reforms. In eight years he will overthrow Han and proclaim a new Xin dynasty. It will go badly. For now the court in Chang'an pretends the Middle Kingdom is eternal.
Han is enormous. Population in the tens of millions. Paper is already invented (Cai Lun is still ahead as the "official" hero, but people already try writing on thin material). Silk, iron, census, canals, Confucian officials. To the north, the Xiongnu, a steppe people: now peace, now war, now a silk bribe.
China knows that far to the west there is some Daqin: Rome. Knows it vaguely. Rome knows Serica, the silk country, vaguely too. No direct embassy in year 1.
India and beyond
Northern India has long been fragmented after the fall of the Mauryas. In the northwest the trail of Greco-Bactrians and Sakas is still felt. The Kushan Empire as a great bridge between China and Rome will form a little later. In the south, their own kingdoms; sea trade with Egypt is already running: they know the monsoon, pepper sails into the Red Sea.
In Southeast Asia: early states, Indian influence, not empires on the Han scale.
Japan is in the Yayoi world: rice, bronze, not yet a "mikado country" in our sense.
The north and the "barbarians"
Beyond the Rhine and Danube: tribes Romans lump together as Germans. They have their own chiefs, their own gods, no wish to become a province. Scythians and Sarmatians on the steppe. On the future Russian lands: forest, hillforts, a wholly different rhythm. No Kiev, no Novgorod. Almost nine centuries until the Varangians.
In Africa south of Egypt: Kush/Meroë. The Sahara is not empty: gold and caravans already draw the road that later great kingdoms will follow.
In the Americas, their own worlds: in Mesoamerica the late Olmecs are already past; cultures like the beginnings of Teotihuacan are rising. The Mediterranean knows nothing of this.
What it feels like
The first year of the Common Era is a year without the name "first."
A Roman thinks: the world is ordered, Augustus fixed it, the gods are for the City. A Chinese thinks: the emperor is the thread between Heaven and people; barbarians should bring tribute. A Parthian thinks: Romans are heavy to get moving; the steppe and the horse are ours. A Judean thinks of the Law, the Temple, and when foreign rule will end.
Nobody marks the "start of an era." An ordinary year is born: tax, wedding, sea wind, a rumor of a legion on the border.
What follows:
- year 9: Teutoburg; Rome forever backs off from deep Germany;
- around year 14: death of Augustus, Emperor Tiberius;
- years 9-23: Wang Mang and the collapse of his reforms;
- the 30s: the execution of Jesus in Judea, which Rome will learn of much later as a "sect";
- year 70: destruction of the Temple;
- year 220: end of Han.
Year 1: silence at the peak of two empires. Rome and Han do not yet suspect how alike they are: both count themselves civilization, and the rest as the edge. Between them, silk. Over the silk they will later write a new era. In this year itself the ink still counts from the founding of the City and from Emperor Ping's accession.
