  1. -490 Battle of Marathon: The conventionally accepted date for the Battle of Marathon. The Athenians and their Plataean allies defeat the first Persian invasion force of Greece.

    490 BC battle in the Greco-Persian Wars

    The Battle of Marathon took place in 490 BC during the first Persian invasion of Greece.

    The Sixteen Kingdoms, less commonly the Sixteen States, was a period in Chinese history from AD 304 to 439 when the political order of the Jin dynasty (266–420) in northern China fragmented into a series of short-lived dynastic states. Most of these states were founded by the "Five Barbarians" – Xiongnu, Xianbei, Di, Jie, Qiang – non-Han peoples from northern and western China who launched the rebellions that toppled the Jin court in Luoyang in 311 and Chang'an in 316, ending the Western Jin dynasty (266–316). Some of these peoples, notably the Xiongnu of Shanxi and the Di of Guanzhong had lived in China for generations and were highly sinicized.

    The Battle of Portopí was an open field military conflict between the Almohad troops that occupied the island of Majorca and the Christian army led by King James I the Conqueror with the aim of annexing it to the Crown of Aragon in order to expand their domain and return it back to Christiandom. It was carried out at various points in the current Sierra de Na Burguesa, approximately halfway between the current resort town of Santa Ponsa and the City of Majorca. It was the second major battle in the campaign for the conquest of the island of Majorca initiated by the Aragonese king.
