Levon I of Armenia vs Rudolf I of Germany

Levon I conquered the fertile Cilician plain from the Byzantine Empire and local Armenian lords. This territorial expansion provided the economic and agricultural base for his kingdom and secured access to the Mediterranean coast.

Levon I formed alliances with the Crusader states, particularly the Principality of Antioch. He married Sibylla of Lusignan and established close ties with the Knights Templar and Hospitaller, integrating Cilician Armenia into the Crusader political system.

Levon I issued a legal code that combined Armenian customary law with elements of Byzantine and Frankish law. This code regulated feudal relations, trade, and criminal justice, and became the foundation of Cilician Armenian jurisprudence.

Levon I was crowned King of Armenian Cilicia by the Archbishop of Mainz, acting on behalf of the Holy Roman Emperor, and also received recognition from the Byzantine Empire. This coronation established the Kingdom of Cilician Armenia as a sovereign state.

Rudolf I was elected King of Germany by the prince-electors, ending the Great Interregnum. He was the first Habsburg to hold the German throne. His election restored stability to the Holy Roman Empire after a period of civil war and weak central authority.

Rudolf I formally renounced all imperial claims to the Papal States and recognized the temporal authority of the Pope. He also agreed to lead a crusade (which never materialized). This improved relations with the papacy and secured papal support for his rule.

Rudolf I defeated King Ottokar II of Bohemia at the Battle on the Marchfeld in Austria. Ottokar was killed in the battle. Rudolf then secured the duchies of Austria, Styria, and Carniola for the Habsburg dynasty, laying the foundation for their future power.

Rudolf I formally enfeoffed his sons Albert and Rudolf with the duchies of Austria and Styria at the Diet of Augsburg. This established the Habsburgs as a major territorial power in Central Europe. The grant was later confirmed by the imperial princes.
