Kingdom of Poland (Premysloides Dynasty)

History
Until Lithuanian integration to Roman Empire, contact between Kingdom of Poland and Roman Empire was only very sporadic. Historical informations (from Polish side) claiming some contacts between Roman emissars in Kraków in 1291, but no embassy was established and no official imperial documents confirming this rumors.

In 1319, first direct contact was made by Emperor Andronikos the Navigator, who initiated negotiation in timber trade deals. These negotiations were prolonged, contrary to Hungarian swift negotiations. Deal was made in 1331 and next year broken, when anti-Imperial Forces destroyed Roman Empire presence in Pomeranian and western Lithuania and western Baltic.

All contacts were severed when Emperor Andronikos was informed about supplying of anti-Imperial Forces from Poland (mostly food and armament) and about Polish own trade negotiations with anti-Imperial Forces.

In 1333, Emperor Andronikos published decree forbidding all Polish civilians to live in Roman Empire, but it was rather propagandistic and symbolic, than real act, as presence of Poles in Roman Empire was minimal.
