The Westerlands

Kingdom
The Westerlands is one of the original four southern kingdoms, and is best known for being the source of multiple failed schemes and plots. By the end of the first summer, The Westerlands had been responsible for multiple cases of failures in leadership, deception, backstabbing and failed plots, which eventually resulted in the kingdoms complete dissolution into a puppet-vassal of The Tyrells of Highgarden. Following this, the kingdom was eventually resurrected into a lordship under the control of the Tyrells, lead in their name by a set of Lannisters, who returned from foreign lands to fix their families mistakes.

After a elongated state of peace and general prosperity, The Kingdom was granted it's independence by The Tyrells of Highgarden. With their former ruler's assistance, they were able to become a relevant and influential kingdom once more, and began to involve themselves in the grand politics of Westeros.

During the mid year of the second summer, The Westerlands faced pressure from their allies, The Tyrells, to bend the knee and press the Tyrell claim to become the Lords of the Seven Kingdoms. In the ensuing chaos, The Westerlands became a key figure in the formation of a Coalition, and eventual defensive pact against The Reach. Achieving this through a chain of multiple deceptions, The Lannisters had once more entrenched themselves in a nearly inescapable web of a lies. The grand result of this was the combined forces of The North and Reach arriving on their doorstep, and following the meeting a deceleration of war. Having to now contend with almost 6000 men, The Westerlands eventually once more underwent a complete change in regime, and their government completely fell apart.

By the end of the second summer, The Westerlands effectively were the split property of The North and The Reach.
