Croatia was later subject to Hungarian hegemony under ban Levin Rauch when the Empire was transformed into a dual monarchy of Austria-Hungary in 1867. Nevertheless, Ban Jelačić had succeeded in the abolition of serfdom in Croatia, which eventually brought about massive changes in society: the power of the major landowners was reduced and arable land became increasingly subdivided, to the extent of risking famine. Many Croatians began emigrating to the New World countries in this period, a trend that would continue over the next century, creating a large Croatian diaspora.
