Here are some significant events from the year 1311:

	1.	Battle of Halmyros (March 15, 1311): The Catalan Company, a mercenary group originally hired by the Byzantine Empire, defeated the forces of the Duchy of Athens in Greece. After their victory, the Catalans took control of the Duchy of Athens, establishing a lasting rule there.
	2.	Council of Vienne (1311-1312): Pope Clement V convened this council in Vienne, France, to address various issues in the Catholic Church, including the suppression of the Knights Templar. This council ultimately led to the disbanding of the Templars in 1312.
	3.	Beginning of the Yuan Dynasty Census: In 1311, Emperor Renzong of the Yuan Dynasty in China initiated a major census. This census aimed to record the population under Mongol rule, which helped in administrative management.
	4.	Political Changes in Europe: Henry VII of Luxembourg continued his efforts to strengthen his position as Holy Roman Emperor. His actions influenced power dynamics across Italy, which was divided between Guelphs and Ghibellines (pro-papal and pro-imperial factions).
	5.	Economic and Trade Developments: The European economy saw increasing importance of trade networks, particularly with the development of new routes linking European ports with Asia and the Middle East.

Each of these events contributed to shifts in power and influence across Europe and Asia, shaping the medieval world.
