Kingdom is an EP by the Polish death metal band Vader. It was released on 21 August 1998 in Japan by Avalon Marquee, and in United States, Europe, and Poland on 10 November 1998 via Pavement Music, Metal Mind, and System Shock/Impact Records.
Kingdom was recorded, and mixed in July, August, and December 1997, and February 1998 at Selani Studio in Olsztyn, and 2.47 Studio in Warsaw. Enhanced track contains PC CD-ROM Data track with video for "Incarnation" in Video For Windows format, encoded using four different quality settings. Piotr "Peter" Wiwczarek talked about remixes on the album, saying:
To be honest, we had to do it because nobody wanted to release the album with like fifteen minutes total time. So, we had a couple of remixes made with different friends and there was even an idea to make a full album just with remixes, but we found out it's not a good idea, we don't need it. We're Vader and... it's not good. It's not bad to put two songs as bonus tracks, to kind of experience something, but nothing more, I guess.[2]
