Question: Another group of residences, known as the Village, is located in the northwest corner of Danforth Campus. Only open to upperclassmen and January Scholars, the North Side consists of Millbrook Apartments, The Village, Village East on-campus apartments, and all fraternity houses except the Zeta Beta Tau house, which is off campus and located just northwest of the South 40.

Question: In the late 14th century, the Songhai gradually gained independence from the Mali Empire and expanded, ultimately subsuming the entire eastern portion of the Mali Empire. The Songhai Empire's eventual collapse was largely the result of a Moroccan invasion in 1591, under the command of Judar Pasha. The fall of the Songhai Empire marked the end of the region's role as a trading crossroads. Following the establishment of sea routes by the European powers, the trans-Saharan trade routes lost significance.

Answer:
Moroccan invasion in 1591
