Battle of the Red Wedding: In the original storyline Robb Stark his mother Catelyn and many of his bannermen were betrayed and killed at the infamous Red Wedding. If Robb had survived the Freys and Boltons would have failed in their plot. Robb would have likely continued his campaign against House Lannister posing a significant threat to their rule in the Seven Kingdoms.
Northern Rebellion: Robb’s survival would have rallied the Northern houses even more strengthening their resistance against the Iron Throne With his leadership Robb might have been able to reclaim lost territories and unite the North under his banner.
The War of the Five Kings: Robb survival would have also affected the dynamics of the ongoing War of the Five Kings His continued presence would have posed a major challenge to the other particularly Joffrey Baratheon and Stannis Baratheon Robb’s military prowess and the loyalty of his bannermen would have increased his chances of success.
Daenerys Targaryen’s Arrival: If Robb Stark had survived Daenerys arrival in Westeros would have faced a different landscape With a strong Northern army backing him Robb might have negotiated an alliance with Daenerys especially considering her ties to the North through Jon Snow This alliance could have reshaped the power dynamics and potentially influenced the outcome of the Targaryen restoration.
It’s important to note that these are speculative outcomes as the story of “Game of Thrones” is known for its unpredictability.Robb Stark’s survival would undoubtedly have had a significant impact on the political landscape and the ongoing conflicts in the series.
