Input: Read this: The rapid expansion of the Rus' to the south led to conflict and volatile relationships with the Khazars and other neighbors on the Pontic steppe. The Khazars dominated the Black Sea steppe during the 8th century, trading and frequently allying with the Byzantine Empire against Persians and Arabs. In the late 8th century, the collapse of the Göktürk Khaganate led the Magyars and the Pechenegs, Ugric and Turkic peoples from Central Asia, to migrate west into the steppe region, leading to military conflict, disruption of trade, and instability within the Khazar Khaganate. The Rus' and Slavs had earlier allied with the Khazars against Arab raids on the Caucasus, but they increasingly worked against them to secure control of the trade routes.
Question: What led to constant problems with the Khazars?

Output: rapid expansion of the Rus' to the south


QUES: In 1744, Burke started at Trinity College Dublin, a Protestant establishment, which up until 1793, did not permit Catholics to take degrees. In 1747, he set up a debating society, "Edmund Burke's Club", which, in 1770, merged with TCD's Historical Club to form the College Historical Society; it is the oldest undergraduate society in the world. The minutes of the meetings of Burke's Club remain in the collection of the Historical Society. Burke graduated from Trinity in 1748. Burke's father wanted him to read Law, and with this in mind he went to London in 1750, where he entered the Middle Temple, before soon giving up legal study to travel in Continental Europe. After eschewing the Law, he pursued a livelihood through writing.
