John of Cologne, O.P. (Joannes van Hoornaar), was a friar and priest of the Dominican Order, born in the Electorate of Cologne, part of modern Germany. He later became a parish priest of Hoornaar, in the Spanish Netherlands. He was executed for his faith in 1572 and has been declared a martyr and saint by the Catholic Church.

In the period 1550-1560 the Dutch Provinces were trying to gain their independence from the Spanish empire of King Philip II. The "sea beggars" were adventurers, pirates and patriots fighting against the Spanish rule in the Dutch provinces.

For several years their bases of operation included the ports of Emden (on the coast of the Dutch Province Friesland), La Rochelle (on the coast of France) and Dover (on the coast of England). The Sea beggars attacked vessels of almost any nation as well as fishing villages and towns on the coast of the Dutch Provinces.

All that is known of John's early life is that he attended the University of Cologne, then recognized as one of the best educational institutions in Europe. He entered the Dominican Order at Cologne and received his formation there. After completing his education, John was assigned to a parish in the Netherlands village of Hoornaar, where he served for the next twenty years.

By 1572, Lutheranism and Calvinism had spread through a great part of Europe. In the Netherlands this was followed by a struggle between the two denominations in which Calvinism was victorious. On 1 April of that year Calvinists and a group called the Watergeuzen (Sea Beggars) conquered Brielle (Den Briel) and later Flushing. In June of that year, Dordrecht and Gorkum also fell into their hands. There they arrested all the Catholic clergy and held them in confinement, in an attempt to get them to deny the Catholic beliefs on the Eucharist and papal primacy.
