Boleslaw mounts a counteroffensive against Shvarn and his uncle Vasilko Romanovich and defeats the former on June 19, 1266 at Wrota.

This weakens Shvarn's position in his own domain.

The Mongols of the Ilkhanate have been at war with the Mongols of the Golden Horde since Hulagu's reign.

This continues into Abaqa's reign, and the Golden Horde invades the Il-khanate in the spring after his accession.

Part of this is due to an alliance between the Golden Horde and the Egyptian Mamluks, in that the Golden Horde is attempting to distract Abaqa on one front, to keep him from invading Mamluk-held Syria on another.

Mamluk Sultan Baibars, having seized power in 1260 and united Egypt and Syria, now embarks on a systematic conquest of Crusader strongholds, expanding his domain by capturing the city of Byblos (in present-day Lebanon) and …

…the important castle of Toron.

The conflict between the Armenians and the Mamluks had begun when the Mamluk Sultan Baibars summoned the Armenian ruler Hethum I to abandon his allegiance to the Mongols, accept himself as a suzerain, and remit to the Mamluks the territories and fortresses Hethum has acquired through his alliance with the Mongols.

Following these threats, Hetoum I had gone to the Mongol court of the Il-Khan in Persia to obtain military support.
