Timeline

Every April 9 on record

  1. 193 The distinguished soldier Septimius Severus is proclaimed emperor by the army in Illyricum.

    Roman emperor from 193 to 211

    Lucius Septimius Severus was Roman emperor from 193 to 211. He was born in Leptis Magna, Libya in the Roman province of Africa. As a young man he advanced through the customary succession of offices under the reigns of Marcus Aurelius and Commodus.

  2. 475 Byzantine Emperor Basiliscus issues a circular letter (Enkyklikon) to the bishops of his empire, supporting the Monophysite christological position.

    The foundation of Constantinople in 330 AD marks the conventional start of the Byzantine Empire, which fell to the Ottoman Empire in 1453 AD. Only the emperors who were recognized as legitimate rulers and exercised sovereign authority are included, to the exclusion of junior co-emperors who never attained the status of sole or senior ruler, as well as of the various usurpers or rebels who claimed the imperial title.

  3. 537 Siege of Rome: The Byzantine general Belisarius receives his promised reinforcements, 1,600 cavalry, mostly of Hunnic or Slavic origin and expert bowmen. Despite shortages, he starts raids against the Gothic camps and Vitiges but is forced into a stalemate.

    First siege of Rome during the Justinian's Gothic War

    The siege of Rome of 537–538 AD was the city's first siege during the Gothic War (535–554) between the defending Byzantine Empire's forces under the leadership of Belisarius against a numerically superior Ostrogothic (Goths) force under Vitigis. The siege was the first major encounter between the forces of the two opponents, and played a decisive role in the subsequent development of the war.

  4. 1241 Battle of Liegnitz: Mongol forces defeat the Polish and German armies.

    13th-century battle during the Mongol invasion of Poland

    The Battle of Legnica, also known as the Battle of Liegnitz or Battle of Wahlstatt, was fought between the Mongol Empire and combined European forces at the village of Legnickie Pole (Wahlstatt), approximately 10 kilometres (6 mi) southeast of the city of Legnica in the Duchy of Silesia on 9 April 1241.

  5. 1288 Mongol invasions of Vietnam: Yuan forces are defeated by Trần forces in the Battle of Bach Dang in present-day northern Vietnam.

The campaigns are treated by a number of scholars as a success due to the establishment of tributary relations with Đại Việt despite the Mongols suffering major military defeats. In contrast, modern Vietnamese historiography regards the war as a major victory against the foreign invaders.
