Andrew III of Hungary
Ladislaus Kán took control of the whole of Transylvania after the death of Andrew III of Hungary in 1301. During the ensuing interregnum, Kán also usurped the administration of Székely Land. Royal authority was restored only after his death in about 1315. In that year, Charles I of Hungary made the brothers Thomas and Stephen Losonci counts. Their successor, Simon Kacsics, was dismissed in 1327 or 1328, because he had committed "serious crimes", according to a contemporaneous royal charter. Thereafter, the office was almost continuously held by the Lackfis for about 50 years.
