Input: Consider Input: 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.

Input: Consider Input: Question: Which of the sons was born first? Passage:In addition to Shahrbanu, the historian Al-Masudi provides the names of four other children of Yazdegerd III; two sons, namely Peroz and Bahram, and two daughters, Adrag and Mardawand. While it was historically recorded that her brothers had escaped to the Tang emperor of China, Islamic traditions state that Shahrbanu's sisters were captured alongside her. One allegedly married Abdullah, son of the Caliph Umar, and became the mother of his son Salim, while another married Muhammad, son of the Caliph Abu Bakr, and became the mother of his son Qasim. Further alleged siblings have also been attributed to Shahrbanu, including Ghayanbanu, who was her full sister, Izdundad, who married the Jewish exilarch Bostanai, and Mihrbanu, who married Chandragupta, the Indian king of Ujjain.
