Show co-creator D.B. Weiss states that in the GoT world: “Marriage was definitely politics by other means, it was one of the prime sources of glue that held people together in larger societies,” while book series author George R.R. Martin adds: “Marriage was a way to bind two families together; it was a form of political alliance.”
They go on to examine several different marriages from the show. Of the upcoming royal wedding between Joffrey and Margaery, the producers believe that the only purpose of the union is to stabilize the realm by joining the two wealthiest families in Westeros: the Lannisters and the Tyrells.
Next, they talk the importance of Sansa Stark. Since everyone believes Bran and Rickon Stark to be dead, Sansa Stark will be the heir of Winterfell once Robb Stark is out of the way. This is why the Tyrells plotted to wed Loras Tyrell to Sansa, and also why Tywin Lannister beats them to the punch by wedding Tyrion to Sansa. Tywin also arranges for Cersei Lannister to marry Loras Tyrell, that way the Lannisters will be in control of the North, South and the Iron Throne. As George R.R. Martin puts it, “It’s all for the glory of House Lannister.”
Finally, they discuss the wedding of Robb Stark to Talisa. By marrying Talisa, Robb broke his vow to marry Walder Frey’s daughter, costing him a major ally in the war. “The decision to marry Talisa definitely divided Robb’s bannermen,” reveals Weiss. Richard Madden, who plays Robb, adds: “It’s the one dishonorable thing Robb has done.” Now that Robb’s uncle, Edmure Tully, is set to marry one of Frey’s daughters, it doesn’t truly make up for Robb breaking his oath. “It’s still kind of a door prize in the political marriage race,” quips Weiss.
The producers insist marriage will continue to play an important part in the political maneuverings of Westeros, so send in your RSVPs, because the GoT wedding events are just beginning!
