founder of liberal philosophy:

Spinoza’s last move, in 1670, was to The Hague, where he was to live out his remaining years. Besides having to deal with fallout from his Theological-Political Treatise, he witnessed a political revolution that culminated in the murder of the Grand Pensionary of Holland, Jan De Witt, along with his brother, Cornelius, by an angry mob of Orangist-Calvinists. Spinoza admired De Witt for his liberal policies and was horrified at the murder. With the ascent of the Orangist-Calvinist faction, he felt his own situation to be tenuous. https://iep.utm.edu/spinoza/
