The ultimately unsuccessful Colloquy of Poissy opens in an effort to reconcile French Catholics and Protestants.

The Colloquy at Poissy was a religious conference which took place in Poissy, France, in 1561. Its object was to effect a reconciliation between the Catholics and Protestants (Huguenots) of France.The conference was opened on 9 September in the refectory of the convent of Poissy, the French king (aged 11) himself being present. It broke up inconclusively a month later, on 9 October, by which point the divide between the doctrines appeared irreconcilable.
