Su Song publishes his Xin Yi Xiang Fa Yao, a treatise outlining the construction and operation of his complex astronomical clocktower built in Kaifeng, China.

Published in 1092, it also includes a celestial atlas of five star maps.

Cumans invade and plunder the eastern territories of the Hungarian kingdom in 1091 or 1092.

Bernold of St. Blasien narrates that Duke Welf of Bavaria prevented "a conference that" Emperor Henry IV "had arranged with the king of the Hungarians" in December 1092.

A letter of the emperor clearly refers to "the alliance into which" he "once entered with" Ladislaus.

Pope Urban II also mentioned in one of his letters that the Hungarians "left the shepherds of their salvation", implying that Ladislaus joined the antipope's camp, possibly because the Pope opposed his expedition to Croatia in 1089-91.

The smallness of Hungary’s Jewish community does not prevent Ladislaus from enacting measures to separate Jews as much as possible from Christians.

Jews are prohibited from working on Sunday, owning slaves or marrying Christians.

Despite this, no overt anti-Jewish measures are imposed.

Vratislaus dies of a hunting wound on January 14, 1092, after a reign of thirty years.

His brother succeeds him as Duke Conrad I of Bohemia.

He does not succeed as king, because his brother had only been lifted to the royal dignity ad personam by the Emperor Henry IV and that title is therefore not hereditary.

Before he became duke of Bohemia, he had long ruled over Moravia, as junior sons typically do, as duke of Brno and Znojmo (since 1054).

By his marriage to Wirpirk of Tengling, he has two children: Oldřich (or Ulrich), prince of Brno from 1092, and Luitpold, prince of Znojmo from 1092.

Dying on September 6, 1092, Conrad is succeeded as duke by his nephew Bretislaus, the eldest son of the late Vratislaus II and Adelaide, daughter of Andrew I of Hungary.

Iconium, located near the imperial frontier in central Anatolia, had been taken from the Empire by the emerging Seljuq Turks in 1072 or 1082.

Renamed Konya, it becomes the capital of the Seljuq sultanate of Rum (Rome) in 1092.

Roger's rule in Sicily has become more absolute than that of Robert Guiscard in Italy.

In addition, due to immigration by Lombards and Normans, Latin Christianity gradually replaces that of the Greek Orthodox tradition.

At the enfeoffments of 1072 and 1092, no great undivided fiefs are created.

The mixed Norman, French and Italian vassals all owe their benefices to the count.

No feudal revolt of importance will arise against Roger.

Jordan, who had been present at the siege of Noto in February 1091, has been made lord of Noto and count of Syracuse and here he dies, of fever, probably in 1092.

Despite having inherited all the Hauteville attributes which had made their rule in the Mezzogiorno all but inevitable, Jordan had not been in line for the succession on account of his illegitimacy until his brother Geoffrey became a leper, then he had been designated heir apparent.

A stone recording his death can still be seen in the church of Santa Maria in Mili San Pietro, near Messina.

The occupying forces of the Almoravids are made up largely of horsemen, totaling no less than twenty thousand.

Into the major cities of al-Andalus, Seville (seven thousand), …

…Cordoba (one thousand), five thousand bordering Castile and four thousand in western Andalusia, succeeding waves of horsemen, in conjunction with the garrisons that had been left there after the Battle of Sagrajas, make it difficult for the Taifa emirs to respond.

The Almoravid infantry uses bows and arrows, sabers, pikes, and javelins, each protected by a cuirass of Moroccan leather and iron-spiked shields.

During the siege of the fortress town of Aledo, in Murcia, previously captured by the Spaniard Garcia Giménez, Almoravid and Andalusian hosts are said to have used catapults, in addition to their customary drum beat.
