As capital city and seat of the government, Pristina creamed off a large share of Yugoslav development funds channeled into Kosovo. As a result, the city's population and its economy changed rapidly. In 1966, Pristina had few paved roads, the old town houses had running water and cholera was still a problem. Prizren continued to be the largest town in Kosovo. Massive investments in state institutions like the newly founded University of Pristina, the construction of new high-rise socialist apartment blocks and a new industrial zone on the outskirts of Pristina attracted large number of internal migrants. This ended a long period when the institution had been run as an outpost of Belgrade University and gave a major boost to Albanian-language education and culture in Kosovo. The Albanians were also allowed to use the Albanian flag.
