The West Slavs included the ancestors of the peoples known later as Poles, Pomeranians, Czechs, Slovaks, Sorbs and Polabians. The northern so-called Lechitic group includes, along with Polish, endangered Pomeranian and Polabian, a dead language; Silesian, which is variously considered a Polish dialect or a language in its own right, is also part of this group. The Sorbian languages of the southern part of the Polabian area, preserved as relics today in Upper and Lower Lusatia, occupy a place between the Lechitic and Czech-Slovak groups.
