Great Wallachia also Thessaly Wallachia, was a medieval state (twelfth and thirteenth century) of the Aromanians (Vlachs), which included the mountains of Thessaly in Greece, the southern and central ranges of Pindus and extending over part of Macedonia.
Anna Komnene in the second half of the eleventh century was the first author to write about the Vlach settlements of the mountains of Thessaly. Benjamin of Tudela, the next century, wrote the earliest account of the independent state of “ Great Wallachia ” in the mountains. He wrote that “ No man can go up and battle against them and no king can rule over them “.
After the Latin conquest of Constantinople in 1204, Great Wallachia was included in the enlarged Despotate of Epirus, but it soon reappeared as an independent principality under its old name.
