Hnefatafl (meaning King’s Table, aka “Viking Chess”) is a board game that originated in Northern Europe; the oldest board found to date was located in Denmark, dated to ~ 400 BC. Because no written history of that period for northern Europe exists, apart from runic inscriptions on stone, wood, and bone, the rules of this game had to be recreated, so there are no hard and fast rules agreed upon by those who play it. It is far older than chess, which originated in northern India in the 6th century AD and spread to the rest of the world through Persia.
In Hnefatafl, the game is played on a square board (as pictured). There are five spaces on the board that are considered special: The space in the centre of the board is the ‘Throne’ space, and the four corner spaces are the escape points for the King.
Unlike most modern board games, Hnefatafl does not start with even-strength sides (as in chess). The two sides are divided into attackers and defenders; in the illustration, the pieces along the edges of the board are the attackers, and those in the centre are the defenders. The objective of the attacker is to capture the king (centre). The objective of the defenders is to protect the king long enough for him to escape.
The board shown above is a modern version; but online, I’ve seen a wide variety of boards, from draw-bags of leather with stone pieces to wooden blocks on a large outdoor board. I’m certain that the travelling Norse, who loved board games, word games and competitions of any sort, would have made do with whatever was at hand and would have also had travel versions of their favourite games, just like we do today.
