Ottokar II acquired Austria in 1251 by marrying the widowed Duchess Margaret of Babenberg, then pressed his dynastic ambitions so aggressively that he eventually controlled a contiguous bloc stretching from Bohemia to the Adriatic — the largest territorial accumulation under any Přemyslid ruler. These Vienna pfennigs were the working currency of that expansion, struck through the full quarter-century of his Austrian tenure until Rudolf of Habsburg defeated and killed him at Marchfeld in 1278.
The Marchfeld battle effectively ended Přemyslid power in Austria permanently.
