Tywin Lannister's Heir and the Dynamics of Westerosi Inheritance

In the world of A Song of Ice and Fire by George R.R. Martin, inheritance and succession play crucial roles in the political landscape of Westeros. This article explores the complex dynamics surrounding Tywin Lannister's decision to designate his heirs in the aftermath of young Jaime's decision to join the Kingsguard. We will also examine the legal and personal implications of this decision and the potential heirs.

Tyrion Lannister as an Official Heir

After Jaime Lannister joined the Kingsguard, he effectively disqualified himself from inheriting his father's titles and lands. Consequently, Tywin Lannister's official heir became his youngest son, Tyrion Lannister. However, their relationship was strained, with Tywin often viewing Tyrion as a disappointment. This decision was rooted in more than just family dynamics; it was also influenced by Tywin's complex plans for his legacy and the internal dynamics within the Lannister family.

The Absence of a Rival Heir

Tywin Lannister had two sons, Tyrion and Kevan. While Kevan was not as intelligent as his brother, he was intelligent enough to manage the Westerlands should Tywin pass away. Had Tywin disowned Tyrion or passed him over as his heir, Kevan Lannister would have been the natural choice to rule House Lannister.

It is argued that Kevan would have been the better choice to rule the Westerlands. This is not due to his inherent superiority but rather because Tyrion would have faced significant challenges in asserting his authority over the lords. Under Kevan's rule, matters would have proceeded as usual, with less resistance from the nobility. Despite the potential for succession, Tyrion's uphill battle would have made his reign more contentious and difficult.

The Laws of Primogeniture and Legal Heirship

According to Westerosi inheritance laws of primogeniture, sons inherit before daughters. Therefore, Tywin's two sons would inherit the Lannister titles and lands. After Jaime's joining of the Kingsguard, the second son, Tyrion, became the official heir to Casterly Rock. This legal aspect might seem straightforward; however, it is not without complications.

Despite the clear legal heirship, Tywin's intentions and actions reveal a different picture. He never fully accepted Tyrion as his proper successor, continuing to refer to Jaime as his "son and heir." Tywin clearly had ambiguous power to name his heir or force his will upon the Lannister family. His intentions to re-inherit Jaime and keep Tyrion out of the loop highlight this complex hierarchy.

Flawed Plans and Secret Opportunities

Tywin's plans for reclaiming Jaime and sidelining Tyrion were always contingent upon the right opportunity. This chance came when King Joffrey Baratheon was killed. Tywin intended to use the situation to discharge Jaime from the Kingsguard and force Tyrion to take the black as a bloodrider. However, his plans were thwarted by a secret passage and a crossbow, a twist that underscores the unpredictable nature of Westerosi politics.

The clear disconnect between the law and Tywin's preparations highlights the tension between legal obligations and personal desires. While Tyrion was legally the heir to the Westerlands, Tywin never planned to let that happen, ultimately ensuring that he maintained control over his family's destiny.
