The County of Hanau-Lichtenberg was a territory in the Holy Roman Empire. It emerged between 1456 and 1480 from a part of the County of Hanau and one half of the Barony of Lichtenberg. Following the extinction of the counts of Hanau-Lichtenberg in 1736 it went to Hesse-Darmstadt, minor parts of it to the Hesse-Cassel. Its centre was in the lower Alsace, the capital first Babenhausen, later Buchsweiler.

The County of Hanau-Münzenberg was a territory within the Holy Roman Empire. It emerged when the County of Hanau was divided in 1458, the other part being the county of Hanau-Lichtenberg. Due to common heirs, both counties were merged from 1642 to 1685 and from 1712 to 1736. In 1736 the last member of the House of Hanau died and the Landgrave of Hessen-Kassel inherited the county.

The Dreikönigsgymnasium ("Tricoronatum", meaning "Three Kings School", sometimes referred to in English as the College of the Three Crowns) is a regular public Gymnasium located in Cologne, Germany. Founded in 1450 by the city of Cologne, it is the oldest school in Cologne and one of the oldest in Germany. In 1556 it was transferred to Jesuit control through the son of the mayor, who had become a Jesuit. The Jesuits continued to run the school until 1778, when control was restored to the city after the papal suppression of the Jesuits of 1773.
