Question

In king arthur's knights, why does king mark decide to take a wife?

Answer 1

The book displays a very realistic and jaded view of the world of chivalry. It is rife with adultery, characterized most visibly in Sir Tristan and the Belle Isolde. However, it should be noted that Sir Tristan had met and fallen in love with Isolde earlier, and that his uncle, King Mark, jealous of Tristan and seeking to undermine him, appears to seek marriage to Isolde for just such a hateful purpose, going so far as to ask Tristan to go and seek her hand on his behalf (which Tristan, understanding that to be his knightly duty, does).

Answer 2

He decides to marry the daughter of another king so that he can have more power and leverage.

Step-by-step explanation:

This is the main reason why King Mark decides to take a wife. The reason why King Mark and Iseult are married is because of a political purpose. However, the princess has fallen hopelessly in love with Tristam, the king's nephew, who was sent to fetch her from Ireland. This will cause both the couple and the king many complications.
