## Events
### By place
#### Byzantine Empire

* Emperor Romanos III Argyros decides to retaliate upon the incursions of the Muslims on the eastern frontier. He leads a Byzantine expeditionary force (20,000 men) to secure Antioch. The Mirdasid emir Shibl al-Dawla Nasr of Aleppo sues for peace, but Romanos refuses to negotiate and leads his army against Aleppo, against the advice of his generals. The Byzantine army encamped near Azaz, where they were encircled by the Mirdasids' Bedouin troops, who cut off the Byzantines from food and water.
* August 10 – Romanos orders a retreat to Antioch. As the army is exhausted from the heat and the lack of supplies, the retreat soon turns into a flight in panic. Romanos returns to Constantinople in humiliation, but his generals on the eastern frontier manage to salvage the situation: a Fatimid attack on Maraclea is repulsed, and Azaz itself is captured in December after a brief siege. In April/May 1031, Emir Nasr of Aleppo agreed to vassal and tributary status with Byzantium.

#### Europe

* June – Emperor Conrad II (the Elder) leads an invasion into Hungary. He plunders the lands west of the River Rába but suffers from the consequences of the scorched earth tactics used by the Hungarians. Conrad, threatened by starvation, is forced to retreat to Germany. King Stephen I pursued his forces, which were defeated and captured by the Hungarians at Vienna.
* July 29 – Battle of Stiklestad: King Olaf II Haraldsson (St. Olaf) attempts to reconquer Norway with help from King Anund Jakob of Sweden. He is defeated by a superior Norwegian peasant and Danish army (14,000 men). Olaf is killed in the battle. He is later canonized and becomes the patron saint of Norway and Rex perpetuum Norvegiae ('the eternal king of Norway').
* The first mention is made of Tartu, Estonia, as Grand Prince Yaroslav I (the Wise) of Novgorod and Kyiv defeats the Estonians and finds a fort named Yuryev (modern-day Tartu). The Rus' will hold the fortress for 30 or 31 years.
