Problem: At the end of the 15th century the Ottoman Empire advanced all over Southeastern Europe, eventually conquering the Byzantine Empire and extending control over the Balkan states. Hungary was the last bastion of the Latin Christian world in the East, and fought to keep its rule over a period of two centuries. After the tragic death of the young king Vladislaus I of Hungary during the Battle of Varna in 1444 against the Ottomans, the Kingdom was placed in the hands of count John Hunyadi, who became Hungary's regent-governor (1446–1453). Hunyadi was considered one of the most relevant military figures of the 15th century: Pope Pius II awarded him the title of Athleta Christi or Champion of Christ for being the only hope of resisting the Ottomans from advancing to Central and Western Europe.

Problem: The Duchy of Lancaster is one of two royal duchies in England. It has landholdings throughout the region and elsewhere, operating as a property company, but also exercising the right of the Crown in the County Palatine of Lancaster. While the administrative boundaries changed in the 1970s, the county palatine boundaries remain the same as the historic boundaries. As a result, the High Sheriffs for Lancashire, Greater Manchester and Merseyside are appointed "within the Duchy and County Palatine of Lancaster".
