Hembyze, Jan van

▪ Flemish Calvinist

Hembyze also spelled  Imbize  

born July 9, 1513, Ghent, Flanders

died Aug. 4, 1584, Ghent

      Calvinist leader who overthrew Ghent's Roman Catholic-dominated government (1577) during the Netherlands' struggle for freedom from Spanish control.

      Supported by Francis van de Kuthulle, lord of Ryhove, and the leading Calvinist preacher, Petrus Dathenus, Hembyze led some 2,000 troops and Calvinist townspeople in battle against their Catholic neighbours on Oct. 28, 1577. He arrested Philip de Croy, duke of Aerschot, the stadholder of Flanders, as well as Ghent's several Catholic magistrates, and replaced them with 18 Calvinists, with himself as mayor. Encouraged by Hembyze, the Calvinist townspeople pillaged churches, destroyed religious statues, and burned six monks to death. William I, prince of Orange, the most important political leader in the Netherlands, supported these actions.

      In 1578, however, when Hembyze attempted to suppress Catholicism completely, the Prince, who was a moderate Calvinist and had guaranteed religious toleration to Catholics and Calvinists alike, opposed him. In December 1578 the Prince, with the support of Lord Ryhove, forced Hembyze to lift restrictions against Catholic worship. In March 1579, however, Hembyze, supported by the radical Calvinist elector John Casimir of the Palatinate (now in Germany), again instituted a policy of harsh discrimination. As a result, the Prince invaded Ghent (August 1579), and Hembyze fled to the Palatinate, where he remained in exile until August 1583. At that time, while the Roman Catholic duke of Parma was defeating the Calvinist army and regaining control of Flanders for Spain, Hembyze returned to Ghent and was elected mayor of the town. Then, upon the interception of letters between him and Parma, a conspiracy to turn Ghent and the surrounding countryside over to Spanish (Catholic) control was discovered. Hembyze was arrested, tried, and executed for treasonous conduct. His sudden actions in favour of Spain, in view of the imminent capture of the town by Spanish forces, which occurred later in 1584, appear to have been motivated by his desire to remain mayor.
