From the Blades wiki page...

On the 30th of Frostfall, 4E 171, the Aldmeri Dominion sent an ambassador to the Imperial City with a gift in a covered cart and an ultimatum to Emperor Titus Mede II. One of the several demands included disbandment of the Blades. Emperor Titus Mede II rejected the ultimatum. The Thalmor ambassador upended the cart, spilling over a hundred heads on the floor: every Blades agent in Summerset and Valenwood. And so began the Great War.
