The language of the ancient kingdom of Baekje (18 BCE – 660 CE), one of the Three Kingdoms of Korea, is sparsely attested; indeed, it is not clear that what material exists is from the same language.Since Baekje was established by immigrants from Goguryeo (the Buyeo-Baekje / Puyo-Paekche), it is presumed that they spoke the Goguryeo language, and several attested words support this idea; however, even if that is true, it is not known which language the indigenous Samhan people (Han-Baekje) spoke, or if the attested material may be a mix of Goguryeo and Samhan.
