Former Grand Pensionary Johan de Witt and his brother Cornelis are lynched by a mob in The Hague.

The grand pensionary was the most important government official during the time of the Dutch Republic. In theory, a grand pensionary was merely a civil servant of the Estates of the dominant province, the County of Holland, among the Seven United Provinces. In practice, the grand pensionary of Holland was the political leader of the entire Dutch Republic when there was no stadtholder at the centre of power.

Battle of Acheloos: Tsar Simeon I of Bulgaria decisively defeats a Byzantine army.

The Battle of Achelous or Acheloos, also known as the Battle of Anchialus, took place on 20 August 917, on the Achelous river near the Bulgarian Black Sea coast, close to the fortress Tuthom between Bulgarian and Byzantine forces. The Bulgarians obtained a decisive victory which not only secured the previous successes of Simeon I, but made him de facto ruler of the whole Balkan Peninsula, excluding the well-protected Byzantine capital Constantinople and the Peloponnese. The battle, which was one of the biggest and bloodiest battles of the European Middle Ages, was one of the worst disasters ever to befall a Byzantine army, and conversely one of the greatest military successes of Bulgaria. Among the most significant consequences was the official recognition of the imperial title of the Bulgarian monarchs, and the consequent affirmation of Bulgarian equality vis-à-vis Byzantium.

Marking the first great wave of Muslim conquests and the rapid advance of Islam outside Arabia, Arab forces led by Khalid ibn al-Walid defeat the Byzantine Empire and take control of the Levant.

Muslims are people who adhere to Islam, a monotheistic religion belonging to the Abrahamic tradition. They consider the Quran, the foundational religious text of Islam, to be the verbatim word of the God of Abraham as it was revealed to Muhammad, the last Islamic prophet. Alongside the Quran, Muslims also believe in previous revelations, such as the Tawrat (Torah), the Zabur (Psalms), and the Injil (Gospel). These earlier revelations are associated with Judaism and Christianity, which are regarded by Muslims as earlier versions of Islam. The majority of Muslims also follow the teachings and practices attributed to Muhammad (sunnah) as recorded in traditional accounts (hadith).
