Bela IV

Bela IV (bā´lə, bē´lə), 1206–70, king of Hungary (1235–70), son and successor of Andrew II. He tried to curtail the power of the magnates and set out to recover the crownlands his father had given to supporters. Confronted by the menace of the Mongol invasion, he sent unheeded appeals to Pope Gregory IX and Holy Roman Emperor Frederick II, but he was crushingly defeated at Mohi on the Sajo River in 1241. Returning after the withdrawal of the invaders, he repopulated the country by inviting foreign colonization. In a battle (1246) with the last Babenberg duke of Austria, the duke was killed but the Austrians were victorious. Bela's long struggle with Ottocar II, king of Bohemia, for Austria and Styria ended (1260) in defeat. His last years were disturbed by the rebellion of his son, later King Stephen V.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
