TREATY OF CALAIS
October 24, 1360

The Treaty of Calais gave France and England a short break during their Hundred Years' War.

What had happened?

In 1356, the English managed to capture French King John II at the Battle of Poitiers and were willing to release him for an enormous amount of money, fixed in the Treaty of Bretigny.

Now, let's have the events in 1360 once more:

The Treaty of Bretigny was concluded on May 8, 1360.

On October 9, 1360, John was released to help raise the money.

On October 24, 1360, the Treaty of Calais was concluded, confirming peace between England and France under the conditions of the Treaty of Bretigny.

Why didn't the Treaty of Calais end the war?

Because it didn't settle the main issues England and France were bitching about. English king Edward III still thought he was the right man for the French throne and the French still wanted the English off the mainland. Therefore, the treaty didn't end the war.
