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 Dutch 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.

Johan de Witt was a Dutch statesman and mathematician who was a major political figure during the First Stadtholderless Period, when flourishing global trade in a period of rapid European colonial expansion made the Dutch a leading trading and seafaring power in Europe, commonly referred to as the Dutch Golden Age. De Witt was elected Grand Pensionary of Holland, and together with his uncle Cornelis de Graeff, he controlled the Dutch political system from around 1650 until the Rampjaar of 1672. This progressive cooperation between the two statesmen, and the consequent support of Amsterdam under the rule of De Graeff, was an important political axis that organized the political system within the republic.

Cornelis de Witt was a Dutch States Navy officer and statesman. During the First Stadtholderless Period, De Witt was an influential member of the Dutch States Party, and was in opposition to the House of Orange. In the Rampjaar of 1672 he was lynched together with his brother Johan de Witt by a crowd incited by Orangist partisans.

The Hague is the capital city of the South Holland province of the Netherlands. With a population of over half a million, it is the third-largest city in the Netherlands. Situated on the west coast facing the North Sea, The Hague is the country's administrative centre and its seat of government, and has been described as the country's de facto capital since the time of the Dutch Republic, while Amsterdam is the official capital of the Netherlands.
