Matthias of Austria, a member of the House of Habsburg (February 24, 1557 - March 20, 1619) was Holy Roman Emperor and Archduke of Austria (1612 – 1619), king of Hungary (as Mátyás II) and Croatia (as Matija II) since 1608 and king of Bohemia (also as Matyáš II) since 1611. His personal motto was Concordia lumine maior ("Unity is stronger than light").
In spite of these problems, the Ottoman state remained strong, and its army did not collapse or suffer crushing defeats. The only exceptions were campaigns against the Safavid dynasty of Persia, where many of the Ottoman eastern provinces were lost, some permanently. This 1603–1618 war eventually resulted in the Treaty of Nasuh Pasha, which ceded the entire Caucasus, except westernmost Georgia, back into Iranian Safavid possession.
