Bogdan I, or Bogdan the Founder (Romanian: Bogdan Întemeietorul), was the first independent ruler, or voivode, of Moldavia in the 1360s. He had initially been the voivode, or head, of the Vlachs in Maramureș in the Kingdom of Hungary. However, when the first certain record was made of him in 1343, he was mentioned as a former voivode who had become disloyal to Louis I of Hungary. He invaded the domains of a Vlach landowner who remained loyal to the king in 1349. Four years later, he was again mentioned as voivode in a charter, which was the last record of his presence in Maramureș.
