[Q]: Question: Were the Vuippens and Holy Romans allied? Passage:Gümmenen Castle, of which nothing remains, was built by either the Counts of Burgundy or the Dukes of Zähringen as part of the defenses along the Saane, along with Laupen Castle and Grasburg Castle. The castle was built to defend a bridge over the river. By 1391, a village (villa inferiori Dicti castri) had developed around the bridge. In 1259, Peter of Savoy made Gümmenen into an imperial fief and imperial castellans took over the castle and village. In 1282–83 King Rudolph I of Germany forced the Savoy castellan out and granted it to a Habsburg knight, Ulrich II of Maggenberg as a fief. Ulrich's heirs sold the castle, ferry and ford to Fribourg in 1319. Fribourg then granted the lands to the knights of Vuippens, who lost it back to either the Holy Roman Empire or Fribourg in 1325. The castle and village were besieged and destroyed in 1333 during Bern and Fribourg's first war over the Sense and Saane valleys, the Gümmenenkrieg. The peace treaty brokered in 1333 by Queen Agnes returned Gümmenen to Fribourg.

[Q]: Question: Who was the headmaster of Gordonstoun at that time? Passage:John H. Mercer was the third child of Harriet and John W. Mercer. He was educated at private schools in Cheltenham and, later, at Gordonstoun in Scotland. During World War II he served in the British Merchant Marines (1940–46) as a radio man.

After finishing his B.A. in 1949 Mercer went to Canada, where he received his PhD in geography from McGill University in 1954. He was a Research Scholar from 1954 to 1956 at the Australian National University in Canberra, where he studied land use and population in western Samoa.
