Input: John, King of England
When the Archbishop of Canterbury, Hubert Walter, died on 13 July 1205, John became involved in a dispute with Pope Innocent III that would lead to the king's excommunication. The Norman and Angevin kings had traditionally exercised a great deal of power over the church within their territories. From the 1040s onwards, however, successive popes had put forward a reforming message that emphasised the importance of the church being "governed more coherently and more hierarchically from the centre" and established "its own sphere of authority and jurisdiction, separate from and independent of that of the lay ruler", in the words of historian Richard Huscroft. After the 1140s, these principles had been largely accepted within the English church, albeit with an element of concern about centralising authority in Rome. These changes brought the customary rights of lay rulers such as John over ecclesiastical appointments into question. Pope Innocent was, according to historian Ralph Turner, an "ambitious and aggressive" religious leader, insistent on his rights and responsibilities within the church.

What lead to the king's excommunication?
Output: a dispute with Pope Innocent III

Input: Gamal Abdel Nasser
While Nasser was in Syria, King Saud planned to have him assassinated on his return flight to Cairo. On 4 March, Nasser addressed the masses in Damascus and waved before them the Saudi check given to Syrian security chief and Nasser supporter Abdel Hamid Sarraj to shoot down Nasser's plane. As a consequence of Saud's scheme, he was forced by senior members of the Saudi royal family to informally cede most of his powers to his brother, King Faisal, a major opponent of Nasser and advocate for pan-Islamic unity over pan-Arabism.

How was the assassination supposed to have been carried out?
Output: shoot down Nasser's plane

What year was the Hammond-Harwood House built?
Output: 1774
