U really dont know the answer for the question you asking
<span>The Byzantine Empire was a vast and powerful civilization with origins that can be traced to 330 A.D., when the Roman emperor Constantine I dedicated a “New Rome” on the site of the ancient Greek colony of Byzantium. Though the western half of the Roman Empire crumbled and fell in 476 A.D., the eastern half survived for 1,000 more years, spawning a rich tradition of art, literature and learning and serving as a military buffer between Europe and Asia. The Byzantine Empire finally fell in 1453, after an Ottoman army stormed Constantinople during the reign of Constantine XI.</span>
The correct answer is the Hanseatic League.
The Hanseatic League was formed in the 1100s and existed as a confederation of merchant towns in modern-day Germany until the late 15th-century.
The Hanseatic League can be seen as a modern precursor to the European Union, that is, a confederation of economic interests that work to provide mutual benefit.
